House Z22 and Warehouse F88 project is a reconstruction project of a multi-family house with workshop rooms underneath in the area Seefeld of the city of Zurich. The house has been in a core zone since the new regulations. Therefore the outlines of the existing volumes are protected and the project had to be developed in collaboration with the conservation of monuments.

The project is a contextual dialogue with history, the house is 170 years old. The historic, massive stone walls were the starting point for applying new contemporary forms of living – fresh typologies: 5 small apartments in the “house” and 4 residential ateliers in the former workshops.

House Z22

The dwelling house is a townhouse from 170 years ago. The natural stone walls were created so long ago, but even then the walls were plastered. Now we have removed the original plaster layers and this led to a raw state of the natural stone walls, which never existed. It is a reference to the material, the construction and to the ‘work’ itself, how was it made?

The architectonic-social aspect, the bourgeois house of the time, is playing a minor part but it is still the same house from the outside. In a confined space, we have developed a flowing, free-flowing space along the natural stone walls. A new typology of ‘promenade architecturale’ in a confined space, where, depending on the social structure and the course of the day, the programs unfold and communicate with the periphery, the natural stone wall.

The built in light weight structures are plastered with basic plaster – and have a rocky appearance. The materials of the built-in furniture are raw concrete, raw wood and raw plaster.

The wooden windows were mounted directly onto the natural stone slabs with 20cm thick solid wooden frames.

Stone Arches And Concrete Topography

In the workshops we answered to the large natural stone arches with a topography of concrete – a contemporary response to a strong historical element. A stone landscape takes up programs that are only marginal in appearance – tectonics and light are in the focus, filling the space with a poetic force.

Raw Is Finished

We have natural stone walls of one meter width, concrete furniture and wooden windows with a 20 cm solid frame. The dialogue on the historical context consists in the reference of the ‘work’, how and by whom was it made. At that time large stone blocks were stacked together – today, topographies were formed from reinforced concrete.
It’s about the craft.

All the elements were put into the raw original state or it was rebuilt raw – a tribute to the material – without hierarchization. There are no inferior materials. Social contamination and connotation disappear. As a result, the space becomes free and authentic – just as people can be.
