Since 1975 the city of Zürich wanted to cover the Kalkbreite tram depot. Finally, in 2014 the Siedlung Kalkbreite was realised. Around the tram depot Müller Siegrist Architekten designed a shell with housing, stores and a green park on top. This green park is accessible via steep stairs which are a little bit hidden. Once you find and climb them you enter a big inner courtyard.

This courtyard is a nice noiseless bubble inside the city. On one side it is surrounded by houses, the other side is open and provides, specially by nice weather a beautiful on the Alps. In the middle there is a garden, a playground and a small community café. On the more open side there are stairs which contain nice terraces. Some used for gardening, some just to sit and relax. This park is a public outdoor space, but it doesn’t feel like. You have the feeling of being a guest in the park. It is a strong community living in the housing project, walking trough the park, surround by houses you have the feeling everybody is watching you.


53 Main gateways – the stairs which lead up to the park create clear gateway

62 High space – the park is already a higher space, the stairs and terraces provide a nice view over the park

69 Public outdoor room – Almost complete surrounded by houses, you feel like you’re in a new room, which is good as you see the park as an inner courtyard

88 Street café – there is a small café, only used by the people who live in the houses

106 Positive outdoor space – according to the book this must be a positive outdoor space, to my experience it isn’t. The space is only usable in a positive way if you live in the Siedlung Kalkbreite. If you are a ‘foreigner’ you feel watched.

125 Stair seats – a lot of seating options on the more open side of the design
