Here is some text from the architects:
Personeni Raffaele Schärer Architects
ECA/OAI office building Vevey, Switzerland, 2011
The new building completes a city block in the centre of Vevey.

The urban void behind the buildings was a residual space used as a parking lot and for utility purposes.

The intervention took advantage of the void and turned it into a main hall for all the buildings of the block.

The once neglected space became a common area with a big patio and a green roof, offering a garden view for all the buildings around it.

The new five floors office building frames the roof garden without enclosing it and maintains a wide visual panorama on the city and the mountains.
