Primary Stingy Blocks of Flats

Primary Stingy Blocks of Flats, Helin & Co Architects

"Primary-Stingy Block of Flats" project is included in Helsinki City's programme aiming to develop multistorey housing. The objective in the design of the Primary Stingy Blocks was to provide with high quality but affordable housing and minimise total energy consumption.
These primary-stingy flats, consisting of both right-of-residence and owner-occupied homes, number 179 in all. The buildings are on two city blocks with a north-south pedestrian and bicycle passage between them. Energy is saved by heating the buildings with a low-heat hydronic floor heating system, by providing floor heating and ventilation installations with at home/away switches, and by connecting washing machines to hot water. The flats have pellet fireplaces and maintenance systems and the shared saunas have low-carbon pellet stoves. The heat from the stoves is utilised in the heating of shower water (there are no flat-specific saunas). All spaces use district heating and electric fixtures are energy saving.
The buildings form a large, sheltered city block with a unified appearance. The ground floor contains a private kindergarten and business or office spaces. The two city blocks have shared outdoor areas with playgrounds, and the courtyard of the kindergarten is also available for residents in the evening. The five-storey buildings at the northern side follow the street line; the three-storey buildings at the southern side are curved, solid and closed. The balconies of the flats as well as the outdoor lounging areas of the saunas and club spaces open towards the inner courtyard. At the western edge of the area is a low, green-roofed parking facility.
