Location: Zurich, Switzerland.

Architect: Christian Kerez.

The open structure of this house is given shape and form by the solid, load-bearing wall that slices the space without being divided. Because of the open floor concept, the lighting and the perspectives around the house always change. No distinction or hierarchy exists between the various uses of the apartment. In terms of design and substance, they are all the same.

Slices of the concrete wall are suspended beneath one another, cantilevered, or stacked one on top of the other. The load-bearing structure is made up of them. All the other floors would be affected if a wall was moved on one floor. Their precise location and structurally crucial arrangement are concealed under what appears to be a free-form, unrestricted design.
