Grenzstrasse Winterthur, development of rear courtyard

|Reference properties

The four-storey building has been erected on a limited plot in the Winterthur neighbourhood of Töss. Its slim construction creates a sense of height – a flexible residential tower for inexpensive apartments.


Upright large-scale sliding air-lux windows evenly stretch over the entire surface of the building, emphasising the vertical, while the open stair tower in in-situ concrete adds a sculptural rear column. The apartment buildings are simply and clearly organised: a core with the bathrooms and the kitchen splits the layout into zones of different areas that can be combined or separated via doors.

  • Building category: Apartment building
  • Service: Façade construction/fall protections made of Inox mesh/support beam construction/sheet cladding/exterior shading/railing construction/exterior doors
  • Façade construction: Façade system with air-tight air-lux sliding windows and steel support beams
