The architecture is based on the design principles of ecological and social sustainability.
Location
The site of a former logistics depot lies 7 km north of Helsinki’s city centre.
The heart of a new housing district
The depot area will be transformed into a new urban district. The size and massing of residential block are defined in the master plan.
Architectural concept
We proposed to break down the massive scale of the block. A variation in floor plan types are combined horizontally and vertically and expressed in the architecture. The block is composed of two elements. The lower part in brickwork masonry ’village’ enlivens street level activity.
Energy solutions
The upper part, a large glazed balcony zone ’the cloud’ straddles the lower. It both shades the apartments and makes use of solar gain.
Public space
The public space is activated at street level via commercial premises and a community centre.
Courtyards
Residential courtyards are forest-like, inspired by the adjacent natural terrain with its mighty conifers and bare rocky outcrops.
Agile housing
The building types within block are designed to meet the needs of differing developers and clients. The “DNA chain” therein formed allows for their flexible development and location within the block.
The first part of the block has been completed with two buildings, in total 60 apartments, for Avara.
Common lobby
The future building for Setlementti, there will be special housing for the elderly among the ordinary dwellings. The entrance connects both stairwells.
The furnished common lobby creates a communal meeting place. The contrasts of the materials lead to safe movement.
