The arrival of a new child in the family pressed a young couple to think about a way to divide a room into two parts. The idea was to provide a personnal space to each child. The projet answers to this request of separation by adding a third space making the partition. The creation of a “multiple-use furniture” in the middle of the space allows to add some depth to the primary basic partition. It afford passages, secret storage, bed, office... in a funny way. The specific blend generates a concentrated typology of spaces and situations in perpetual renewal. The new partition is porous creating steps, cavities and niches wich suggests many possibilities for appropriation (climbing, hidding, drawing, etc...). Many uncharted and intermediate spaces led by the furniture allow for the invention of any kind of practices and uses. Let’s play !
