Start of construction at "Green City House" on Basel´s Sperrstrasse

Five modern new flats are being built in condominium ownership at Sperrstrasse 7 in the centre of Basel. The existing building from 1883 was demolished and is now being rebuilt in the resulting gap in a sustainable timber construction. The open-plan loft-like structure allows an individual layout of 2 ½ to 5 ½ rooms. The materials and surfaces used underline the demand for modernity and ecology. All flats have already been sold.

The "Green City House" project has developed a modern solution with the proverbial principle of a "tooth gap": Unused residential buildings in need of refurbishment are demolished; vacant, empty gaps are closed by replacing them with new houses offering more space and incomparable living quality. But not only that, the newly created buildings are also sustainable due to the combination of a timber system construction with exposed concrete, achieving a CO2 saving of over 35% compared to conventional buildings. The "Green City House" project thus contributes to sustainable urban densification.
