Housing:

Most housing production in Oslo is characterised by mass production and standardised low-cost solutions, but in this project, the client was willing to invest time and resources in the project to achieve a higher quality, both functionally and technically.

The project comprises 33 apartments above a ground floor of commercial units. The building is divided into two slender volumes to avoid deep plans, with galleries screening the apartments from the mainly commercial neighbourhood. 

The two volumes both have roof terraces and embrace a communal landscaped courtyard where a pond system provides local surface water handling.

The construction is a system of stacked timber modules on a concrete foundation. Each apartment consists of several modules, but the plan conceals the module junctions, and the extra wall thicknesses are used for built-in storage.

Landscaping:

Dense and varied planting gives a rich and fertile impression, and song thrushes and sparrows have already moved in. The landscape architects collected seeds from local wild climbers to cover an existing fence.
