PLANNING COMMITTEE 6th August 2020 [email protected]

References: P/2020/0984 00571/A/P5

Address: Churchdale Court, Chiswick, W4 4EE

Proposal: Conversion of the existing roofspace in two blocks to provide four residential units.

This application is being taken to Planning Committee due to significant public interest.

1.0 SUMMARY

1.1 The proposal is for the conversion of the existing roof space at Block A and Block B into four flats, the installation of roof lights and the erection of dormers. The proposal provides a good standard of accommodation which would preserve the character and appearance of the Wellesley Road Conservation Area and the locally listed buildings, and would not harm neighbours’ living conditions.

1.2 The proposal would secure a site-wide 50.43% carbon dioxide emissions reduction against a Building Regulations Part L (2013) baseline.

1.3 The application is recommended for approval subject to conditions.

2.0 SITE DESCRIPTION

2.1 The site is located on the south eastern corner of the junction between Grosvenor Road and Harvard Road. The site is located within the Wellesley Road Conservation Area and the buildings are locally listed.

2.2 The site contains two, three storey rectangular shaped blocks. The two blocks are brick built and are characterised by the single and double canted red clay tile hung bays. The bays have over sailing hipped tiled roofs. Block A fronts onto Grosvenor Road and block B fronts onto Harvard Road. The two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street parking, a designated waste and recycling area and a block of six garages.

2.3 The surrounding area is predominantly residential with two storey, terraced and semi-detached properties. To the north west of the site is the Russian Orthodox Church to the north west of the site.

2.4 To the south of Harvard Road is the A4. The site has a Public Transport Accessibility Level (PTAL) of 3 (moderate) and is within close proximity to Gunnersbury station. The surrounding streets including Harvard Road,

Page 2: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

Grosvenor Road and Wellesley Road are covered by a Controlled Parking Zone (CPZ) which operates Monday to Friday 9am – 6pm.

3.0 HISTORY

0571/A/P3 Conversion of existing roofspaces and extension to roofs of two blocks to provide six flats - (4 Two Bedroom and 2 One Bedroom).

Withdrawn: 06/08/2013 00571/A/P4 Conversion and extensions to the existing roofspaces on

two blocks of flats to provide six additional flats - (4 Two Bedroom and 2 One Bedroom).

Refused: 04/06/2014 Reason: 1. The proposed conversion and extensions to the existing

roof space to provide six residential units would not provide a good standard of accommodation for all occupants owing to inadequate floor to ceiling heights, floor area and amenity space provision. This would be contrary to adopted Unitary Development Plan policies ENV-B.1.1 (New Development) and H.4.1 (Housing Standards and Guidelines); London Plan policy 3.5 and London Plan Housing Supplementary Planning Guide and the intent of the National Planning Policy Framework.

2. The proposed conversion and extensions to the existing roof space to provide six residential units would, owing to the excessive number of additions to the roof, fail to preserve or enhance the character and appearance of the Wellesley Road Conservation Area. It is therefore considered to be contrary to adopted Unitary Development Plan policies ENV-B.1.1 (New Development) and ENV-B.2.2 (Conservation Areas), and the intent of the National Planning Policy Framework.

Appeal dismissed: 22/04/2015

• Erection of six dormers and installation of two roof lights to the rear elevation of Block B;

4.3 The proposal would secure a site-wide 50.43% carbon dioxide emissions reduction against a Building Regulations Part L (2013) baseline.

4.4 The proposal would be car-free and the existing ten car parking spaces and six garages would be retained.

4.5 The proposal would provide eight cycle parking spaces and additional refuse and recycling storage.

5.0 CONSULTATIONS

5.1 53 neighbouring properties and the West Chiswick and Gunnersbury Society were notified on 26/03/2020. A site notice was posted on 01/04/2020 and a press notice on 08/04/2020. 42 responses were received and are summarised below.

Comment Response

The proposed flats are not a significant contribution to the housing target.

See paragraph 7.1 – 7.8.

The proposed roof lights and dormers would harm to the character and appearance of the existing buildings and Conservation Area.

See paragraph 7.19 – 7.29.

Proposed dormers do not align with the existing windows below.

The proposed dormers would be arranged in pairs and evenly distributed across the roof face. This is considered a more appropriate design response.

Increased overlooking. See paragraph 7.43 – 7.47.

Noise and disruption from construction and occupation.

See Condition 4 and Condition 16

Overcrowding. The proposal would provide a good standard of accommodation for the

Page 5: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

proposed number of occupants.

Sub-standard of accommodation: insufficient internal and external space, lack of daylight receipt and poor noise and air quality.

See paragraph 7.30 – 7.42, Condition 14 and Condition 15.

Risk of overheating. Mechanical extract ventilation would be installed and windows would be openable for natural ventilation.

SAP calculations required for all flats.

The sample SAP calculations are considered acceptable for the purposes of the Sustainability and Energy Statement.

Bats roost in roof spaces. See paragraph 7.52 – 7.55. See Condition 13.

No disabled access to the proposed flats although there are two blue badge car parking spaces.

No car parking spaces for the proposed flats are provided. The site plan has been amended to remove the allocation for blue badge spaces. The existing car parking remains unchanged.

Access to existing garages and car parking compromised by proposed cycle and refuse stores.

It is considered there is sufficient space on site to accommodation cycle and refuse stores without compromising access to the existing garages. The details of these stores are required by Condition 7 and 9.

Blue badge car parking spaces not big enough.

The site plan has been amended to remove the allocation for blue badge spaces. The existing car parking remains unchanged.

Increased traffic and congestion. See paragraph 7.48 – 7.51.

Proposed cycle and refuse stores would be unsightly.

The details of these stores are required by Condition 7 and 9.

The proposed cycle stands conflict It is considered there is sufficient

Page 6: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

with the existing tree. space on site to accommodation cycle stores without compromising existing trees. The details of these stores are required by Condition 7.

Insufficient space for cycle stands. It is considered there is sufficient space on site to accommodation cycle stores. The details of these stores are required by Condition 7.

Cycle stands should be provided for existing residents.

This falls outside the considerations for this planning application.

Inappropriate positioning of bin stores.

The details of these stores are required by Condition 9.

Damage to the WWll air raid shelter on site.

The shelter is located within the central landscaped area between Block A and Block. It is considered that there would be no conflict between the construction and operational phase of the development and the shelter.

Concerns over fire safety and escape routes.

See Informative 5.

Concerns about breaching of existing obligations/covenants.

Not a planning consideration.

Decreased sale/rental values. Not a planning consideration.

Compensation required for noise and disruption.

Not a planning consideration.

Freeholder has provided poor maintenance in the past.

Not a planning consideration.

Concerns about impact on existing infrastructure: water pressure, wiring and sewage disposal.

The proposal would be CIL liable to mitigation these impacts.

Page 7: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

Concerns about the structural integrity of the existing buildings.

Not a planning consideration.

5.2 The application was placed on the Pending Decisions List dated 24th – 31th July 2020 (Week 30) as a minor planning application to be considered by committee.

External Statutory Consultation Responses

5.3 The following external bodies were notified of the application and their response are detailed where these have been received:

Transport for London

5.4 No objection.

Amenity groups and societies

5.5 West Chiswick and Gunnersbury Society

The WCGS objects to the proposals and requests that the application be refused.

1.We recognise that the current proposals are an improvement with respect to those (00571/A/P4) which were refused by the LPA in 2014 and for which the appeal was dismissed in 2015. However, we consider that they are neither acceptable nor compliant with planning policy. Our objections relate to quality of accommodation, impact on residents of existing flats and impact on the Locally Listed building and the Wellesley Road Conservation Area.

Quality of accommodation

2.Squeezing 2 two-bedroom flats into the roof space of each building would not provide a sufficiently high standard of accommodation for the future residents of these flats. We consider that the design and layout of the flats within the roof-space would provide poor quality accommodation. While the rooms may meet the minimum space standards they are not generous and the percentage of the room space with a ceiling height of at least 2.3m only just scrapes by the 75% requirement. The arrangement of furniture would be seriously constrained by the sloping ceilings and the rooms would not provide comfortable living spaces. The plans show essential furniture in positions in which it would not be usable, for example, seating from which occupants would be unable to stand upright. Relying on a single dormer plus rooflights for natural lighting of the living areas together with the low ceilings would result in poor quality accommodation. The quality would be especially poor for the flats in Block B where the main fenestration, the dormers, face north.

Page 8: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

3. In addition, the main bedroom in flat 1 (Block A) is compromised by being positioned next to the kitchen/diner of flat 2.

4. The flats would have no private outdoor amenity space and no additional communal outdoor space would be provided. This would amount to a deficit of 124 m2 of outdoor amenity space.

Impact on amenity of residents of existing flats

5. Increasing the total number of flats within Churchdale Court to 34 would reduce the communal outdoor space per flat from 23 m2 to 20.3 m2. The Local Plan standard (SC5) requires 25 m2 per unit. Adequate outdoor space is especially important in an area of public open space deficit. While Harvard Hill recreation ground is relatively close, access to it from the application site is via an inhospitable A4 underpass. As a result of this severance, the small park is used mainly by residents of the Grove Park area of Chiswick to the south rather than by residents of West Chiswick and Gunnersbury to the north. It also suffers noise and pollution from its proximity to the A4 as it runs alongside the west-bound carriageway of the A4 east of the Chiswick Roundabout.

6. The importance of open space (private, communal and public) to people’s health and wellbeing has been highlighted by the current coronavirus pandemic. The likelihood that similar situations will arise in future means that great weight should be given to providing a sufficient amount of suitable space within each development.

Impact on heritage assets

7. Churchdale Court comprises two attractive, landscaped, three-storey, 1930’s apartment blocks which are included in the Council’s Local List (CH110). We note that this status is not acknowledged within the application. All elevations are visible from the street (either Grosvenor or Harvard Road) and the buildings make a very positive contribution to the character and appearance of the Wellesley Road Conservation Area.

8. The addition of six large dormers to the rear elevation of both buildings, together with several rooflights to front and rear would have a negative impact on the character and appearance of the buildings. This harm would not be consistent with Local Plan Policies CC1 and CC4.

Planning balance

9. On balance, the addition of 4 flats of poor quality does not outweigh the harm to the amenity of residents of the existing flats and to the character and appearance of these Locally Listed buildings within the Wellesley Road Conservation Area.

10. The WCGS requests that the application be refused.

6.0 POLICY

Determining applications for full or outline planning permission

6.1 The determination must be made in accordance with the development plan unless material considerations indicate otherwise. Local finance considerations must also be assessed.

The National Planning Policy Framework

6.2 The National Planning Policy Framework (NPPF) was revised on 19 February 2019. The April 2014 National Planning Practice Guidance (NPPG) is an online guidance resource that supports the NPPF. Where pertinent, the NPPF and NPPG are material considerations that will be taken into account in decision-making.

6.3 The Development Plan for the Borough comprises the Council's Local Plan (adopted by the Council on 15 September 2015), the West London Waste Plan and the London Plan Consolidated with Alterations since 2011.

6.4 The draft New London Plan has been through Examination in Public, but has not yet been adopted. The weight given to it remains a matter for the decision maker at this stage.

6.5 The Council are currently undertaking two Local Plan Reviews; the West of Borough Local Plan review and the Great West Corridor Local Plan review. Consultation on the ‘Preferred Options Consultation’ document for both these reviews, and amendments to the adopted Local Plan, was undertaken between 23 October 2017 and 10 December 2017. The policies of these draft Plans are capable of being a material consideration in planning decisions. Their policies will gain more weight as it moves through the examination process to adoption; however the weight given to them is a matter for the decision maker. At this stage the Local Plan Reviews are being prepared for the formal Regulation 19 Public Consultation due to take place in May 2019 therefore the policies contained within them will carry more weight.

Determining applications in a conservation area

6.6 In considering whether to grant planning permission with respect to any buildings or other land in a conservation area, special attention shall be paid to the desirability of preserving or enhancing the character or appearance of the conservation area.

7.0 PLANNING ISSUES

The acceptability in principle

7.1 The National Planning Policy Framework (NPPF) states that the development plan is the starting point for decision making. Proposed development that accords with an up-to-date Local Plan should be approved, and proposed development that conflicts should be refused unless other material consideration indicate otherwise.

7.2 The NPPF paragraph 59 identifies as one of the strategic policies as ‘Government’s objective of significantly boosting the supply of homes’ and paragraph 123 states ‘where there is an anticipated of existing shortage of land for meeting identified housing needs, it is especially important that planning policies and decisions avoid homes being built at low densities, and ensure that the developments make optimal use of the potential of each site’.

Page 11: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

7.3 In relation to new housing, the London Plan encourages high quality schemes for housing developments that make more efficient use of land. It states that good design should contribute positively to making places better for people.

7.4 London Plan Policy 3.3 (Increasing London’s Housing Supply) recognises the need for more homes in London so as to promote opportunity and provide a real choice for all Londoners in ways that meet their needs affordably. Policy 3.4 (Optimising Housing Potential) states that, taking into account local context and character, the design principles outlined in Chapter 7 of the Plan and public transport capacity, development should optimise housing output for different types of location.

7.5 Draft London Plan Policy H1 would increase the Borough’s Housing Target to provide for 21,820 homes over the plan period (2019/20-2028/29). Draft Policy H2 proposes a specific target for new homes delivered on small sites over the plan period. For Hounslow this would be 6,800.

7.6 Local Plan policy SC1 (Housing Growth) states that the Council will support proposals for new residential development and conversions on other sites, including small sites, in the context of presumption in favour of sustainable development.

7.7 Churchdale Court is a residential development and the surrounding area is predominately in residential use. The proposed residential use would therefore be compatible with the site and surrounding area and would deliver much needed housing. This would accord with the objectives of the NPPF, the London Plan and adopted Local Plan policies. The proposal would therefore be acceptable in principle, notwithstanding the other planning issues that will be discussed in turn.

7.8 The other main planning issues to be considered are:

• Energy and Sustainability

• Design and Appearance

• Standard of Accommodation

• Impact on Neighbouring Uses

• Transport, Highways and Access

Energy and Sustainability

Policy context

7.9 The broad aim of sustainable development is to ensure that the quality of social, economic and ecological environments are improved and maintained for future generations. The London Plan and adopted Local Plan encourage sustainable development through many policies including promoting the use of energy efficient building design and materials, re-use of previously developed land and existing buildings, and location of development in or close to town centres and areas with good public transport. Sustainability is also a clear thread running through the NPPF.

Page 12: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

7.10 Sustainability underpins many London Plan and local adopted policies. These require developments to be sustainable in transport terms, to minimise waste, include energy efficiency measures and promote use of renewable energy, and not significantly increase the requirement for water supply or surface water drainage.

7.11 As a new development, the proposal can make a substantial contribution to sustainable development in the Borough and it is important that it recognises and adopts sustainable development principles.

7.12 London Plan policy 5.2 (Minimising carbon dioxide emissions) requires developments to make the fullest practicable contribution to minimising CO2 emissions following this energy hierarchy:

• Be Lean: use less energy;

• Be Clean: supply energy efficiently; and

• Be Green: use renewable energy

7.13 It continues that development proposals should include a detailed energy assessment to demonstrate how the targets for carbon dioxide emissions it outlines are to be met within the framework of the energy hierarchy.

7.14 The Mayor aims to ensure that major developments reduce carbon dioxide emissions from buildings, by reaching higher than the Target Emission Rate (TER) outlined in the national Buildings Regulations, leading to zero carbon buildings from 2016.

7.15 Policy EQ1 of the Hounslow Local Plan seeks to minimise the demand for energy and promote renewable and low carbon technologies and Policy EQ2 aims to promote the highest standards of sustainable design and construction in development. It goes on to state that where appropriate developments should make a financial contribution to an agreed borough-wide programme for carbon reductions where required reductions cannot be achieved on-site.

Assessment

7.16 An Energy Statement has been submitted in support of this application which sets out how the proposed development will achieve the reductions in CO2 emissions required by the above policies and meet the other sustainability criteria set out in these policies. This has been reviewed by the Council’s Sustainability Consultant.

7.17 The applicant has incorporated the energy hierarchy into the design in order to show how the development would secure a site-wide 50.43% carbon dioxide emissions reduction against a Building Regulations Part L (2013) baseline. This approach is based primarily on the use of solar PV panels on the roof of the building and air source heat pumps. The Council’s Sustainability consultant has advised that the approach is acceptable and has recommended that these details be secured by condition, including measures to incorporate sustainable sourcing of materials in the construction phase and other sustainability credentials.

Page 13: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

7.18 As a result of the ‘zero carbon’ homes policy, a payment of £9,559 (subject to confirmation by as-built calculations) would be required into the Council’s Carbon Offset Fund. All payments are required to be secured through a Unilateral Undertaking.

Design and Appearance

Policy context

7.19 The NPPF states good quality design is an integral part of sustainable development and that decision takers should always seek high quality design. It states that achieving good design is about creating places, buildings or spaces that work well for everyone, look good, will last well, and adapt for the needs of future generations, with good design responding in a practical and creative way to both the function and identity of a place, putting land, water, drainage, energy, community, economic, infrastructure and other such resources to the best possible use. The NPPF also says permission should be refused for development of poor design that fails to take the opportunities available for improving the character and quality of an area and the way it functions. It is proper to seek to promote or reinforce local distinctiveness.

7.20 London Plan policy 7.4 (Local Character) sets out that buildings should provide a high quality design response to the urban grain, street pattern, natural features, human scale and the historic environment and is supported by Policy 7.6 (Architecture) which seeks to promote high architectural and design quality appropriate to its context.

7.21 Local Plan Policy CC1 recognises the context and varied character of the Borough’s places, and seeks to ensure that all new development conserves and takes opportunities to enhance their special qualities and heritage.

7.22 Policy CC4 (Heritage) states that development proposals should conserve and take opportunities to enhance any heritage asset and its setting in a manner appropriate to its significance.

Assessment

7.23 The site contains two, three storey rectangular shaped blocks. The two blocks are brick built and are characterised by the single and double canted red clay tile hung bays. The bays have over sailing hipped tiled roofs. Block A fronts onto Grosvenor Road and block B fronts onto Harvard Road. The two blocks comprise of 15 flats in each (a total of 30).

7.24 The proposed rear roof dormers would be grouped in pairs and evenly distributed across the rear roof slope. They would feature windows of a similar proportion and design to the existing building and would be set-up from the eaves by 2.63m, set-down from the ridge by 1.88m and be well set-in from the side elevations. Although glimpses of the rear dormers would be visible from Harvard Road and Grosvenor Road, they would not be easily visible from the surrounding area given they are positioned internally within the site and on the rear roof slopes of the blocks. The appropriate size, scale, position and design of the proposed rear roof dormers would ensure they

Page 14: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

appear as subservient additions to the original buildings and preserve the character and appearance of the site and the Wellesley Road Conservation Area.

Figure 2 - Proposed Dormers (Block A - Rear Elevation) 7.25 The proposed roof lights on the front and rear roof slopes and the proposed

solar panels on the rear roof slope of Block A would be positioned flush with the existing roof slope to minimise their impact on the appearance of the existing building and the surrounding area. The appropriate position and design ensures that they would preserve the character and appearance of the site and the Wellesley Road Conservation Area.

Page 15: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

Figure 3 - Proposed Roof Lights (Block B Front Elevation) 7.26 Churchdale Court is a locally listed building. The Local List states that

Churchdale Court is “A good example of 1930s residential blocks. The buildings occupy a prominent position on a spacious corner plot with attractive landscaping and makes a very positive contribution to the Conservation Area. The complex forms an unusual but harmonious addition the otherwise mainly significantly older estate.” For the reasons outlined above, it is considered that the proposed extensions and alterations at roof level have been designed to respect the character and appearance of the existing buildings and would not undermine the significance of the locally listed building.

7.27 The proposal includes the provision of a refuse and recycling store within the car park towards Grosvenor Road. Whilst the location of the store is acceptable in principle, further details are required as to the appearance of the store to ensure that it preserves the character and appearance of the site and the Wellesley Road Conservation Area. These details would be secure via condition.

Other matters

7.28 It is noted that planning application 00571/A/P4 for the creation of six flats in the existing roof space was refused and dismissed on appeal due to, but not limited to, the impact on the character and appearance of the Conservation Area. The refused proposal featured front and side roof dormers in a variety

Page 16: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

of sizes, enlarged gable elements on the front roof slope, and eight dormers across the rear roof slopes of which three contained roof terraces. These elements have been omitted from the current proposal.

7.29 The current proposal is considered a more refined version of the previous proposal and would make limited interventions into the fabric on the original buildings and only the minimum amount necessary to achieve a good standard of accommodation. It is therefore considered the proposal overcomes the previous reasons for refusal and would not harm the character and appearance of the Wellesley Road Conservation Area.

Standard of Accommodation

Internal Space Standards

7.30 The proposed accommodation would include:

Block Unit No. Size Internal Floor Area (m2)

Internal Floor Area above 2.3m (m2)

Internal Floor Area above 2.3m (%)

Block A Flat 1 2-bed/3-person

61m2 46m2 75.4%

Block A Flat 2 2-bed/3-person

61m2 46m2 75.4%

Block B Flat 3 2-bed/3-person

61m2 46m2 75.4%

Block B Flat 4 2-bed/3-person

61m2 46m2 75.4%

7.31 Local Plan Policy SC5 requires development proposals to demonstrate compliance with the Nationally Described Space Standards (NDSS). The NDSS requires all new units to meet the minimum internal floor areas specific to the number of bedrooms/occupants and that 75% of that minimum internal floor area be at least 2.3m in height when measured from finished floor to finished ceiling height. The above tables shows that all units have been designed to meet these minimum space standards, both in terms of internal floor area and internal floor to ceiling height. The proposal would therefore comply with the requirements of the NDDS and would provide a good standard of accommodation for future occupiers.

Privacy, Outlook and Daylight

7.32 The London Plan Housing SPG recognises that older planning guidance for privacy sought to achieve visual separation between dwellings by setting minimum distances of between 18-21m between habitable rooms, with these distances being useful yardsticks for privacy. This requires each

dwelling to be provided with an adequate level of privacy in relation to neighbouring property, the street and other public spaces.

7.33 The scheme has been designed to achieve the requirements of the Housing SPG in respect of separation distances ensuring residents would be afforded appropriate levels of privacy. The minimum separation distance between the proposed flats would be 21m.

7.34 The scheme has also been designed to ensure residents benefit from appropriate outlook and daylight receipt, in particular through the siting and layout of the individual units and their interrelationship, with all units being dual aspect. A Daylight and Sunlight Study has been submitted in support of the application which confirms that the proposal complies with BRE requirements for ‘Site Layout Planning for Daylight and Sunlight’.

External Amenity

7.35 The proposal would not provide private amenity space for the proposed flats. This approach has been taken so as not to encroach on the character and appearance of the locally listed buildings through the additional of balconies and/or terraces.

7.36 The existing site has a central landscaped area between Block A and Block B. This provides 690m2 of communal amenity space for the existing 30 flats. The proposal would increase the number of flats on the site to 34 which would decrease the percentage share of communal amenity space per flat from 23.0m2 to 20.3m2.

7.37 There is an additional 574m2 of grassed area around the site fronting Harvard Road and Grosvenor Road. These areas have been omitted from the calculation as they are less private and more disjointed that the central amenity space. If these areas were taken into account it would result in 37.2m2 per flat.

7.38 Harvard Hill Recreation Ground is opposite the site on the other side of the A4/M4 and accessed via a subway. It is designated local open space, is approximately 190m walking distance from the site and also includes a play area. Turnham Green is somewhat further at 610m walking distance from the site.

7.39 It is considered that the proposal provides a good quality, usable amenity space. Although the proposal does not provide sufficient communal amenity space in accordance with Local Plan policy SC5, it is considered that the shortfall is mitigated by the close proximity to designated local open spaces within walking distance.

Other matters

7.40 It is noted that planning application 00571/A/P4 for the creation of six flats in the existing roof space was refused and dismissed on appeal due to, but not limited to, the poor standard of accommodation by virtue of cumulative shortfalls. The Inspector found the proposed flats sub-standard in terms of internal floor area, floor to ceiling heights and the amount of amenity space.

Page 18: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

7.41 The Inspector did however state that the lack of additional external amenity space would not, in itself, be a reason to dismiss the appeal.

7.42 The current proposal seeks permission for four flats (a reduction of two in comparison to the previous proposal) which provide accommodation in accordance with the relevant standards. The shortfall in external amenity space is considered a reason for reason consistent with the Inspector’s decision for the previous proposal.

Impact on Neighbouring Uses

Policy Context

7.43 London Plan policy 7.6 states that buildings and structures should not harm the amenity of surrounding land and buildings, particularly homes, in relation to privacy, overshadowing, wind and microclimate. Local Plan Policy CC2 reflects this aim and particularly emphasises the need to protect existing residents’ living conditions.

7.44 The London Plan Housing SPG recognises that older planning guidance for privacy sought to achieve visual separation between dwellings by setting minimum distances of between 18-21m between habitable rooms, with these distances being useful yardsticks for privacy.

Assessment

7.45 The proposed roof lights would be flush with the roof slope. The proposed rear roof dormers would be set up from the eaves by 2.63m, set-down from the ridge by 1.88m and distributed evenly across the rear roof face in pairs. The proposed extensions and alterations would be of a size, scale, position and design that would not harm neighbours’ living conditions, in terms of loss of light or outlook. The position of the extensions and alterations to the roof would create a relationship between existing and proposed properties not dissimilar to the relationship that exists at present. It is therefore considered that the proposal would not harm neighbours’ living conditions, in terms of outlook and loss of privacy.

7.46 The design and external appearance of the proposed development has been assessed in detail in the preceding section on Design and Appearance and was considered to be acceptable and would not harm existing residents’ outlook.

7.47 Although the proposal would increase the number of units on the site, six new flats are not considered to result in any unacceptable increase in noise and disturbance to neighbouring residents.

Transport and Highways

Policy context

7.48 Local Plan Policy EC2 (Developing a Sustainable Local Transport Network) has regard to transportation and seeks to secure a more sustainable local travel network that maximises opportunities for walking, cycling and using

Page 19: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

public transport, reduces congestion, improves the public realm and improves health and well-being. It echoes the London Plan in terms of standards established for car parking, cycle parking, motorcycle parking, coach parking, and electric vehicle charging, along with any additional standards set in supplementary guidance.

Assessment

7.49 The site has a PTAL of 3 and is therefore considered to have moderate accessibility to public transport. Gunnersbury station is a 350m walk away, and it is less than 600m to Chiswick Town Centre as defined by the Local Plan. The site is in Chiswick West CPZ that operates Monday-Friday, 9am-6pm.

7.50 No car parking spaces would be provided for the proposed flats. This is considered acceptable given the accessible location. A restriction for future occupiers from obtaining parking permits for the surrounding CPZ would be secured via condition. The existing ten car parking spaces and six garages would be retained.

7.51 Eight cycle parking spaces would be provided. This is considered acceptable and complies with the London Plan. The proposed cycle spaces should be sheltered and enclosed. These details would be secure via condition.

Biodiversity

7.52 There have been a number of consultation responses from neighbouring residents which suggest that the existing roof spaces and surrounding trees are used by bats to roost.

7.53 The applicant has stated that there is no evidence of bat roosts present on site and no bat surveys have been undertaken.

7.54 Natural England’s species standing advice states that bats are likely to use buildings that have large roof areas, roofs warmed by the sun and early 20th century buildings due to their construction materials and methods of construction. It is therefore considered that, given the design, orientation and age of the existing buildings, the site has potential for bat roosts.

7.55 In light on this, a condition is recommended for a bat survey to be prepared by a qualified bat ecologist and submitted to and approved in writing by the Local Planning Authority in consultation with Natural England prior to the commencement of development.

Planning Obligations

7.56 The National Planning Policy Guidance provides advice on use of planning obligations, which may impose a restriction or requirement, or provide for payment to make acceptable development proposals that might otherwise not be acceptable in planning terms.

7.57 Local Plan Policy IMP3 seeks to ensure that development proposals fully mitigate the impacts of the development on the area through a Section 106

Page 20: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

agreement/Unilateral Undertaking, where necessary or appropriate, having regard to supplementary planning documents and to provide the CIL payments required by any charging scheduled, including the Mayor of London’s CIL. A payment or other benefit offered in a Section 106 agreement/Unilateral Undertaking is not material to a decision to grant planning permission and cannot be required unless it complies with the provisions of the Community Infrastructure Levy Regulations 2010 (Regulation 122), which provide that the planning obligation must be:

• necessary to make the development acceptable in planning terms

• directly related to the development; and

• fairly and reasonably related in scale and kind to the development.

7.58 The NPPG provides guidance on use of planning obligations, which may impose a restriction or requirement, or provide for payment to make acceptable development proposals that might otherwise not be acceptable in planning terms. The Council’s Supplementary Planning Document on Planning Obligations (adopted March 2008) contains guidance on imposition of planning obligations in compliance with such guidance. These obligations may offset shortfalls in the scheme or mitigate a development’s impacts.

7.59 The following draft Heads of Terms are likely to form the basis of any Section 106/Unilateral Undertaking or other legal agreement, all of which are considered to satisfy one or more of the three Regulation 122 tests referred to above:

• Carbon Offset Payment @ £9,559.

8.0 EQUALITIES DUTIES IMPLICATIONS

8.1 The public sector equality duty applies to all council decisions.

8.2 A public authority or any person who exercises public functions must, in the exercise of those functions, have due regard to the need to:

(a) eliminate discrimination, harassment, victimisation and any other conduct prohibited by or under the Act;

(b) advance equality of opportunity between persons who share a relevant protected characteristic and persons who do not share it;

(c) foster good relations between persons who share a relevant protected characteristic and persons who do not share it.

8.3 Having due regard to the need to advance equality of opportunity, this involves having due regard, in particular, to the need to:

(a) remove or minimise disadvantages suffered by persons who share a relevant protected characteristic that are connected to that characteristic;

Page 21: PLANNING COMMITTEE 6th... · two blocks comprise of 15 flats in each (a total of 30). The site contains communal amenity space positioned between the two blocks, informal off-street

(b) take steps to meet the needs of persons who share a relevant protected characteristic that are different from the needs of persons who do not share it;

(c) encourage persons who share a relevant protected characteristic to participate in public life or in any other activity in which participation by such persons is disproportionately low.

8.4 This shall include, in particular, but is not limited to steps to take account of disabled persons' disabilities.

8.5 The exercise of public functions must have due regard to the need to foster good relations between persons who share a relevant protected characteristic and those who do not, in particular, to the need to:

(a) tackle prejudice; and (b) promote understanding.

8.6 Compliance with these duties may involve treating some persons more favourably than others. This is not to be taken as permitting conduct that would otherwise be prohibited by or under the Act.

8.7 The relevant protected characteristics are: age; disability; gender reassignment; pregnancy and maternity; race; religion or belief; sex; marriage and civil partnership; and sexual orientation.

8.8 Due regard needs to be demonstrated in the decision making process and requires an analysis of the material with the specific statutory considerations in mind. It does not follow that the considerations raised will be decisive in a particular case. The weight given to them will be for the decision maker. The equalities duty is not a duty to achieve a particular result. Some equalities considerations are covered under other legislation such as Building Control matters. Officers have in considering this application and preparing this report had regard to the public sector equality duty and concluded that due regard has been given to the Council’s duty in respect of its equalities duties and that if approving or refusing this proposal the Council will be acting in compliance with its duties.

9.0 LOCAL FINANCE CONSIDERATIONS

9.1 Local finance considerations means the Community Infrastructure Levy, or a grant or other financial assistance that has been, or will or could be, provided to a relevant authority (such as the Council, the Mayor of London, the Homes and Communities Agency, etc.) by a Minister of the Crown.

10.0 COMMUNITY INFRASTRUCTURE LEVY

10.1 Some new developments granted planning permission will be liable to pay Community Infrastructure Levy (CIL) to the Mayor of London and Hounslow.

10.2 CIL is payable on m2 of new floor space or where a new dwelling is created

10.3 This proposal would be liable to pay the CIL which is index linked.

10.4 The estimated Hounslow CIL payable is £48,800 and Mayoral CIL payable is £14,640.

11.0 CONCLUSION

11.1 The proposal is for the conversion of the existing roof space at Block A and Block B into four flats, the installation of roof lights and the erection of dormers.

11.2 The proposal is considered to provide a good standard of accommodation with access to off-site amenity mitigating the shortfall in on-site communal amenity space. The appropriate design of the proposal would preserve the character and appearance of the Wellesley Road Conservation Area and the locally listed buildings, and would not harm neighbours’ living conditions.

11.3 The proposal would secure a site-wide 50.43% carbon dioxide emissions reduction against a Building Regulations Part L (2013) baseline.

11.4 As such, it is considered that the proposal would be an appropriate response to the site and would deliver much needed housing. Overall, the proposal would be in accordance with the objectives and policies of the NPPF, the London Plan and the Local Plan as set out throughout this report.
