The Helsinki region is widening to the west and the new metro construction started in 2012. The City of Espoo launched in the autumn 2012 a competition for the building of a new sub-centre with 300 000 sqm floor area to be built 2015-2030, mainly Housing Quarters and the Commercial Metro Centre. The City invited seven significant Finnish construction companies with their teams to make proposals for detailed town planning. The competition area was divided in 9 subareas of which each invited teams could choose for themselves the most suitable ones. The promise was to carry out best proposals and make contracts with the winning teams about the building of one or more subareas of the Metro Centre.

The Hartela team under the leadership of R&D chief Tero Vanhanen consists of the main designer Cederqvist & Jäntti Architecs in co-operation with ArkOpen and four other consultants for traffic, commerce and various technical and environmental aspects. The team decided to make a proposal, that differed significantly from the preliminary city-layout, concentrating on the central area. The central ideas were to achieve good integration between buildings and landscape and to use Open Building principles to gain advantages for resident adaptation and good life cycle capacity.

The jury of the competition declared the Hartela-team project superior winner and the City of Espoo decided to start city planning of the whole central area with this team. The co-operation work is now in early master plan stage. Closer implementing negotiations will start and other building firms will involved. The design principles are fixed through the competition, but the Centre layout and technical solutions will have some changes during the further work. The design of the main housing types will also start.
