Building Code

Statement

This code considers some of the options for reducing potable water use

in buildings through the careful selection of sanitary ware and ttings.

It also sets specic water conservation measures and targets that will

apply to the Newquay Growth Area.

Specifying sanitary ware which is low or no water use will signicantly

reduce water consumption. This is applicable for both commercial and

residential buildings. In both cases however, the sanitary ware must

meet the performance requirements set out below.

Dwellings

In dwellings water conservation should look to reduce consumption

from an average 175l/d per person to 100l/d with 70% of water for

ushing toilets to be supp lied from harvested rainwater.

Levels of performance to be achieved in dwellings are;

WC’s

• Dual ush toilets shall be installed throughout. 6/3 litre ushtoilets are the minimum standard. 4/2 litre ush toilets are

now available and may be considered subject to approval by

Water Authority and appropriate testing to demonstrate they are

effective at low ush.

• Composting toilets, which require no water. While there are

some on the market which are clean and effective, there is likely

to be signicant consumer aversion to this in the short term. This

may be a technology that is considered for the innovative or

experimental dwellings

Showers

• Low ow showers, with a low ow aeration head rated at below

9 litres per minute should be tted.

Basin and Baths

• Basins and baths should not be oversized.

Taps

• Taps in basins should have ow restrictors or be aerated to

reduce the water ow.

• Taps in kitchen sinks or utility rooms do not need to be aerated

or low ow restrictors as the water used here is generally for

cooking or drinking rather than washing, and so a set amount of

water is required.

4.0 Building Code

Commercial and other Non Residential Buildings

In commercial and ‘dry’ industrial buildings water conservation

should look to reduce consumption from an average of 50l to 90l/

d per person to 40l/d. For commercial uses with canteens and ‘wet’

industrial processes specic targets will be set for individual buildings.

Generally, however, 100% of water for ushing toilets to be supplied

from harvested rainwater.

Levels of performance to be achieved in commercial and other non

residential buildings are;

WC’s

• Dual ush toilets as for dwellings.

• Composting toilets may be considered as an innovative

or experimental measure for some commercial or public

buildings.

Urinals

• Urinals should either be tted with movement detectors, toensure ushing only when required, or should be waterless.

Showers

• Where tted showers shall meet the same performance criteria

as for dwellings.

Taps

• Taps in basins should have ow restrictors or be aerated to

reduce the water ow and should be tted with automatic close

facility.

• Taps in kitchen sinks or cleaning sinks do not need to be aerated

or low ow restrictors as set amount of water is required.

Water Meters

Water supplies to all buildings will be metered. Meter should be in

readily accessible location that will encourage owners to read them

on a regular basis to check their water use and identify early any leaks

developed on their private supply pipes.

Rainwater Harvesting

Rainwater harvesting or recycling will be used for replacement

for potable water in toilet ushing and for irrigation of gardens and

landscaped areas in all buildings and public open spaces to assist in

meeting the minimum requirements set out above.

Grey Water Recycling

Grey water recycling will not be a requirement of the early phases

but developers who are minded to explore this option are requested

to contact the Duchy of Cornwall at the time that their project

comes forward to establish their position with regard to this evolving

technology.

Building Code

Statement

This code considers some of the options for reducing energy and water

use in buildings through the careful section of appliances. It also sets

specic energy and water use measures and targets that will apply to

the Newquay Growth Area

Appliances

Where white goods are provided they shall comply with the Codes

minimum eco labeled energy rating. Developers are encouraged to

install appliance which improve on this minimum standard and meet

the requirements set out below;

Fridges/Freezers

• Energy rating A+ minimum for fridges, freezers and/or fridge

freezers.

Cookers

• Energy rating A minimum, electric/gas ovens and hobs• Provision of microwave ovens.

Dishwashers

• Energy rating A minimum. Rating AAA preferred (AAA gives A

for energy rating, A for wash cycle and A for drying.)

• Water use should be less than 14 litres per cycle for 12 setting

dishwasher

Washing machines

• Energy rating A minimum. Rating A+AA preferred (A+ for energy,

A for wash cycle and A for spin)

• Washing machines should be selected for low water use percycle. Ideally below 50 litre per cycle for a 6kg load.

Washer dryers

• These are inherently less energy efcient and therefore washing

machines are preferred. Where specied at least a B rating for

energy use should be specied. Rating A preferred.

Dryers

• Dryers are energy intensive appliances. Energy rating B minimum.

Rating A preferred.

Where white goods are not provided information on purchasing energy

efcient white goods shall be included in the Home User Guide

Internal Lighting

All internal lighting shall be low energy lights, using tubular, uorescent,

compact uorescent and LED lamps.

The internal lighting design in commercial, mixed use, community andpublic buildings shall be designed by a specialist consultant to ensure

that high quality, efcient light ttings and luminaries with appropriate

diffusers are specied. Individual desktop lighting is preferred over

xed lighting wherever possible, with low background lighting. Motion

sensors shall be incorporated, where appropriate, to enable the lighting

to be switched off automatically when activity stops in a room.

Lighting in all occupied areas should be in zones to allow separate

controls.

External Lighting

All external lighting shall be low energy lights.

Space lighting shall be designed to accommodate only compact

uorescent lamps (CFL).

Security lighting shall be designed to meet the following criteria; all

intruder lighting to be 150 watts maximum and be tted with PIR and

daylight sensor; all other types of security lighting to accommodate

CFL’s or uorescent strips only and be tted with dawn to dusk s ensors

or timers.

Street Lighting shall comply with Code LAN15

The external lighting shall be reduced to minimum levels suitable for

safety and security without being wasteful of energy use.

High levels of ood lighting are restricted to areas of signicant

importance. These areas are identied on the Masterplan.

Statement

High performance standards are also required of nishing materials.

The choice of nishes should not purely be driven by aesthetics. Instead

it should be an integral part of the sustainable ethos. In addition to

the responsible sourcing of nishing materials, set out in Code BE03,

care should be given to their impact on air quality, as well as design

considerations such as their application, appearance and performance

and how it relates to its substructure and adjacent nishes. This holistic

approach to specication will assist in improving the health and well

being of occupants. It should be remembered that natural products, as

well as synthetic, can also contain substances that can cause allergies,

asthma and allergic reactions, as can animals.

The selection of materials should avoid the use of ozone depleting

substances (ODP) and indoor pollutants, such as volatile organic

compounds (VOC), where possible, and should reduce the use of PVC.

Useful websites for eco building products are the GreenPro products

database at www.newbuilder.co.uk ,the Greenpeace website at www.

greenpeace.org.uk and the Construction Resources website at www.

constructionresources.com Where possible materials should be as close to natural as possible;

linoleum not vinyl; timber not chipboard; screwed not glued, oiled or

waxed not varnished and so on.

Paints for both internal and external use shall be environmentally

friendly odourless and solvent free.

Where adhesives are used they shall be low odour and low VOC.

Floors must be designed and built so that any oor of any storey can be

covered with any nishing material, carpet, timber or stone.

For health and sustainable reasons timber ooring is generally

preferred to carpet nish. In wet areas consideration should be given

to ceramic tiles, natural stone or linoleum made from renewable raw

materials. Vinyl ooring should be avoided where possible. Wherecarpets are provided they should be made form natural products such

as wool, sisal or hemp. Foam backing should not be used as it contains

formaldehyde. Recycled carpets are now available.

A minimum of 75% of nishing timber shall be from sustainable sources

selected from suppliers certied by the Forest Stewardship Council

(FSC) or Programme for the Endorsement of Forest Certication (PEFC)

or equivalent and from UK sources where appropriate and available.

The remaining timber shall be of temperate origin.

If laminate or other manufactured boarding is used for ooring, kitchens

etc. it should be FSC or PEFC or equivalent certied. Medium Density

Fibreboard (MDF) shall not be used due to concerns regarding the use

of toxic resins risking formaldehyde off-gassing and lung irritating dust

produced when sawing.

Clay plasters provide a sustainable alternative to conventional plaster

or plasterboard and developers are encouraged to use this where

appropriate. Clay plasters are also excellent at assisting in regulating

temperature and humidity. Clay plasters can be supplied by Natural

Building Technologies website www.natural-building.co.uk or

Construction Resources website www.constructionresources.com

Statement

There is increasing need for alternative approaches to waste disposals

to reduce the reliance on landll and to encourage recycling and waste

minimisation.

Restormel Borough Council operates a four weekly collection schemefor paper, glass, cans and textiles. This is being upgraded to a fortnightly

scheme and will also include collection of cardboard and plastic

bottles

Developers shall work will Restormel Borough Council to ensure that

the current and future provisions for bo th non-recyclable and recyclable

waste are met.

Recycling Bins

To encourage the use of this service, each dwelling must be provided

with space to store recyclable materials, both at source (ie in the

kitchen) and with the general refuge. This provision will assist in making

recycling an everyday part of life.

There are a number of proprietary storage bins which are appropriatefor storage of recyclable waste and can be built into the kitchen. These

range from individual stacking bins of approximately 50 litres, to pedal

bins with two or more compartments. It is suggested that the following

storage should be considered:

• Bin/box for paper, cardboard and textiles. This does not need to

be stored in the kitchen.

• Bin for recyclable waste such as glass, cans, plastic bottles,

either in the kitchen or utility room.

Space for a bin for compostable material, should be provided either in

the kitchen or utility room, together with composting bins in gardens

to all houses to promote the recycling of kitchen waste.

Commercial and Industrial users will be required to provide a waste

management strategy which shall be benchmarked and monitored to

encourage continual improvement.

Tarmacadam and sustainable alternatives

Sustainable principles should inform the selection of surface and

sub-base materials. Materials should obtain not less than a ‘B’ rating

and should aim for an ‘A’ rating under the BRE Green Guide forSpecication. The use of locally sourced materials and appropriately

sourced reclaimed materials are encouraged such as;

• Recycled aggregate. This is generally only appropriate if sourced

from within approximately 30 miles from site, or closer than

non recycled aggregate can be sourced.

• Recycled surfacing. The Highways Agency does allow some

recycled materials in adopted roads. For other surfacing there

may be greater exibility, including materials with a percentage

of recycled materials

Granite

Granite for hard landscaping shall be sourced from local quarries.

Roads will be edged with rough surface granite kerbs with drop kerb

details at junctions with access points to rear courts and individual

properties.

Granite setts will be used for rumble strips, trafc tables and detailing to

tree grilles, as well as surfacing in hard public spaces. Smooth granite

may be acceptable in some locations.

Slate

Slate for hard landscaping shall sourced from local quarries.

Slate ags may be used as a surfacing material in hard public spaces.

Slates should generally be of random rectangular size with all four

edges sawn and laid to a regular patternSlate chippings may be used as decorative mulch and for permeable

road surfaces, as indicated on the Masterplan.

Sandstone

Riven or split face sandstone for hard landscaping shall sourced from

local quarries.

Sandstone ags may be used as a surfacing material in hard public

spaces. Sandstone should generally be of random rectangular size with

all four edges sawn and laid to a regular pattern

Gravel

Gravel shall be to an approved sample. Where identied on the

Masterplan gravel may be used as a surfacing material on minor roads,car parking courts and pavements and footpaths. Gravel areas shall be

edged with either granite setts or timber gravel boards as appropriate.

Where possible gravel surfaces should form an integral part of the

SUDS system.

Block and Brick Pavers

Where permitted in the Masterplan block and brick pavers shall be

permeable, see Code LAN06

Tarmacadam and sustainable alternatives

Generally primary and secondary roads shall be tarmacadam. The

use of sustainable and environmentally friendly alternatives, as well

as recycled materials, will be encouraged. Permeable asphalts areavailable and should be considered where appropriate.

Building Code

Statement

The subsoil allows in almost all areas of the Growth Area for permeable

surface materials to be installed and to function successfully. Permeable

surface materials shall be used where possible for private and shared

access space, car parks and paths.

A permeable surface must be porous and must not clog. It must allow

water to percolate and air to get into the soil

Permeable surfaces should be constructed from recycled local materials

wherever possible. Recommended materials include porous bonded

gravel paving and reclaimed stone cobbles. The Charcon website,

www.charcon.com, and the Interpave website, www.paving.org.uk

provides useful guidance on permeable surfaces and SUDS.

Permeable surface would be required to absorb 180 litre/second/hectare.

Where sub-grades are unable to absorb at this rate, the remainder has

to be retained in the pavement, either to gradually percolate into the

sub-grade or to be taken through a sub-surface drainage system

The removal of permeable surfaces and replacement with impervious

surfaces on private driveways and shared surface will not be allowed.

SUDS proposals. Each phase shall comply with the requirements of

this site wide surface water strategy.

The storm water run-off system from the Growth Area through the SUDS

system will be designed to ensure that the new development does not

increase run-off from undeveloped land and for redevelopment to

reduce run off.

Permeable surfaces shall be used for car parks, residential driveways,

Statement

High quality, accessible play areas are to be provided for children of all

ages within the Growth Area. Play spaces are to be integrated within

the new development in locations indicated on the Masterplan.

Three types of formal spaces are proposed;

• Neighbourhood Equipped Area for Play (NEAP), which is the

largest and is intended for older children between the ages of

eight and fourteen.

• Local Equipped Area for Play (LEAP) for children between the

ages of four and eight.

• Local Area of Play (LAP) for children under the age of six.

In addition to formal play areas, the design uses soft landscaping to

encourage children’s play. The approach is for play to be more integrated

into the landscape and community.

Play areas will require safety surfacing beneath play equipment.

Toilet facilities must be provided on site.

A simple, communal building shall be provided as both a meeting

place, a central location to display messages and a centre for the sale

or distribution of seeds and equipment

Adequate security measures, such as good fences and hedges, will be

Traditional Cornish hedge

Rendered boundary wall Squared ruble stone walling

Rendered boundary wall A cohesive approach to the property boundary

Statement

General Boundary Parameters:

• Front gardens facing onto public spaces will have fences, railings,

wall and/or Cornish hedges. These will be between0.75m and

1.1.m high.

• The boundaries of building plots facing on to rear or garage

courts will have walls of between 1.6m and 2.0m high. These

walls will comprise a 0.9m solid masonry with the additional

height provided by an open timber palisade or trellis fence.

• In front gardens, the detailing of walls, railings or fences used

to dene the frontage of the plot will also be used to dene the

boundary between building plots.

• All properties with boundaries to semi-public space will have

access through those boundaries to that space. Access through

walls will be by a gate of an equal height to the adjacent wall

or fence

• Property boundaries within rear of garage courts will dene

parking spaces and garages associated with individual plots.These will be clearly distinguished by a combination of fences,

walls, and changes in surface materials.

Walls

• Most walls facing public or semi-public spaces will be

constructed in stone of a type to match the surrounding

buildings. Walls should be at least 215mm thick.

• Stone or rendered walls may have a coping detail of slate or

stone

• Rendered walls will have a plinth of 200mm constructed

in either stone, or in blockwork or brickwork painted with

bituminous emulsion

• Continuous walls and coursing over 10 metres in length will

run generally parallel with ground level. On slopes of more

than 20%, walls must be stepped

• Where garage or other walls of buildings are incorporated into

boundary walls the material and outside plane or the walls

should be continuous

• Prominent walls – for example at the entrance to or at key

locations within the development – will be in stone to a height

of 1.6m

Cornish Hedges

• Some boundaries, especially those close to cottage-likedwellings, should be traditional “Cornish hedges”

• Hedges or other boundaries already present in the Newquay

Growth Area are to be retained [subject to the Masterplan] and

integrated into the development. New adjoining boundaries

should successfully blend with the existing

• A standard, free standing stone hedge should usually stand

l.4m above ground level. Boundary stone hedges are often

l.8m or more. The base width should normally be equal to the

total wall height.

• A foundation course is required for all work not built on rock.

• When providing stone, it is important to ensure that all stone

is of sufcient size to provide stretcher and bonding stones.Bonding stones should stretch at least 450mm into the bank

and be placed at metre intervals. Smaller stones can be used

when facing an existing earth bank.

• The inll for stone hedges should be granular earth. It should

be compacted at least every 150mm. Many craftsmen

believe weepholes should only be constructed where special

conditions, such as a spring, make their provision necessary.

• The top, or cap, of the stone hedge may be nished with turf

(most common), cope stones, or a combination of the two. This

is dependant on the exposure of the area.
