Neubau Wohnsiedlung BFG-Areal, Zürich, 2023—2030, Competition 1st Prize

Composite Presence

The heterogeneous development of the surrounding area requires a differentiated urban design: an ensemble of three different building types - a courtyard house, a row of flats and a 60 metre high residential tower - create different and attractive free spaces as well as good spatial transitions to the neighbouring buildings. A sheltered garden courtyard, forecourts facing Baslerstrasse and the Basilisk site and a large, inviting residential garden upgrade the entire neighbourhood.

Three simple, archetypal building types also create a differentiated and attractive range of flats for a diverse tenancy base for this large number of flats. The chosen typologies promote social interaction, revitalise the open spaces and create attractive places to spend time. The desired diversity is also supported by various authors. Giuliani Hönger is responsible for the tower and courtyard house, Tobler Gmür for the row and Studio Vulkan for the free spaces.

The various buildings will also have efficient, sustainable and economical load-bearing structures. A concrete column-slab structure is provided for the tower, a purely timber construction for the row and a hybrid construction with timber columns, concrete beams and reused ceiling slabs from the existing buildings for the courtyard house. Part of the existing car park will also continue to be used, reinforced and extended. In terms of their architectural appearance and colour design, the buildings differ in favour to a lively, modern look.
