In 2012, we transformed the old carpentry workshop located in the backyard into a residential cottage (No. 4b), and then gradually refreshed the main building (No. 4) dating from the late 19th century. In 2025, the commercial building that occupied the entire eastern part of the site was partially demolished to make way for a small 3-story residential building (No. 6) and a communal garden.

Adjacent to the ground floor shop, the entrance is extended by a common room opening onto the garden at the back. Two 5-room apartments are located on the upper floors. Their typologies, orientated on three sides, are inspired by the plans of 19th-century urban villas in Lausanne, with a large central distribution hall and rooms in a row all around.

The expression of the extension refers to these same urban villas. The mansard roof and its cornice wrap around completely, refusing any hierarchy between the sides; the windows are vertical, the base is marked, and the facades are covered with a coarse-grained plaster, similar to that of the main building and the small house.

The apartments at n°4 receive additional rooms, and the small house gets a new opening on the west facade, which provides access to the garden and the evening sun. The result of this 15-year project is a complex formed by the aggregation of three constructions of different sizes and eras, but responding formally, functionally, and symbolically around their common garden.
