PROJECT TITLE:HELSINKI SEASIDE OPEN HOUSING
PROJECT FIRM:SATO LtdPanuntie 4, 00600 Helsinki, Finland / www.sato.�SATO is one of Finland’s leading corporate investors in housing. SATO owns a total of some 23,000 rentable homes in Finland’s largest centers of urban growth and St. Petersburg. SATO’s value proposition is ”A home the way you want it”. The Helsinki Seaside Open Housing Project is managed by Jouko Kuusela and Hannu Korhonen. The architects of the buildings are: co-ordination ArkOpen / Esko Kahri, the Gallery Block ArkOpen / Petri Viita, the Town Houses Portaali / Juha Kämäräinen, the Neo-Urban Apartments Talli / Pia Ilonen,
PROJECT DETAILS: Address: Kalasatama (”Fish Harbour”), Helsinki (former harbour area in the heart of city)Completion year: 2012Structural engineers: Ylimäki – Tinkanen Ltd, HEPAC-engineering: Kartech Ltd, HelsinkiFloor Area: 4500 + 1650 + 4000 = 10.150 sq.mSite Area: 5630 sq.m
A BLOCK OF THREE SUSTAINABLE BUILDING TYPES Base BuildingsThree client groups and three ways of life span thinking: 1. the Gallery Block / small apartments: open structure, installation zones, combinable apartments. 2. the Town Houses: open space + sanitary facilities, optional facades. 3. the Neo-Urban Apartments: a spacious universally usable plan, where the rooms can be used in di�erent ways without spatial changes. Dynamic Uses Changing with TimeThe Gallery Block: apartment sizes according to demand, small apartments can be combined. The Town Houses: alternative layouts, movable walls. The Neo-Urban Apartments: spacious generally applicable rooms that accommodate changing life situations.Participatory ProcessA client service system has been developed for 10 years; a book on the subject has been published in June 2011. The Gallery Block o�ers a choice of interior designs in di�erent styles. The Neo-Urban Apartments o�ers alternatives in surface materials and �xtures + extra accessories. The Town Houses are individual from the layout to the facades, the structure being open for future alterations.User Friendly and Responsive TechnologyThe client service system, developed by the Tocoman / Moor Co, connects the user and the developer online. The service manages information about client choices of layouts, materials and �xtures including costs. Quantity information is passed on to the building site.
SUSTAINABLE BUILDINGThe SATO Team won an Open Building Technology competition in 2001. The proposed system has since then been re�ned and tens of projects have been realized using the concept. The need for �exibility varies for di�erent types of projects. The development block on the Helsinki seaside uses three di�erent types of user in�uence and life span solutions. The rented apartments use a communal building type with social emphasis, including possibilities for combining �ats in the future. The family apartments use a building type that is universally usable without structural alterations. For the demanding customer there are the Town Houses, which provide an urban location combined with individuality from layout to facades. All clients are serviced online. With these principles a socially versatile housing block is formed, that can live and develop in harmony with the changing needs of the inhabitants.
