Langenhagweg Allschwil

Residential Development Basel-Land

Housing Langenhagweg Allschwil

On the outskirts of Basel, four new residential buildings scattered between Langenhagweg to the south and Steinbühlweg to the north will replace the existing 1960’s apartment blocks, and incorporate into the grain of the well-groomed, heterogeneous residential quarter of Allschwil.

The four identical buildings are slightly rotated or mirrored to respond to their location, and to maximise views and light conditions while creating a series of unique outdoor spaces on the site and avoid a monotonous repetition. The buildings are all raised on concrete plinths to obtain the necessary privacy for the apartments on the ground floor.

On each floor, four rentable apartments surround the central core. Varying in size from one to three bedrooms, the flats are always anchored to two facades, giving every apartment multiple views and a corner balcony with maximum exposure. The living spaces are connected to the loggias and are illuminated by room-high glazing and continuous parapet windows. The efficient interior arrangement allows for well-furnished living rooms and bedrooms.

The attic contains a large three bedroom penthouse apartment which is anchored to two sides of the lower building. The setbacks generate a spacious terrace which is partially sheltered by a cantilevered pergola. With generous room heights of 2.60m, a very high quality of space is achieved on a compact floor plan.

The maximum allowable built area is utilised in this development, while simultaneously maintaining a spacious green surrounding. Sustainable design means the housing will achieve Minergie-P certification. An earth source heat pump will supply the development with energy for heating and warm water.
