Although this may seem like a lot of doors, using the common entrance to the building for the commercial properties in fact reduces the number of thresholds in a typical Parisian residential building. However, it increases the awareness of who is coming and going and when, as it forces every person to pass by someone who lives or works in the building.
There are no individual residences on the ground floor. It holds half of the café, half of the day care space, the office for the cohousing community, and the cohousing's communal space which includes kitchen and dining facilities large enough to seat 28-30 people.The first floor hosts the second half of the café, the second half of the daycare and one of the largest individual family units boasting 3 bedrooms and living/dining room + kitchenette in 72m2 (775sq.ft.)

Also on the 1st floor, between the stairwells is a guest unit for the cohousing community, that is available for guests of residents.
