In this apartment, spaces have been optimized to break with the protocol. The living room streches in the entire long. It is created by a ﬂow, linking three spaces allowing an open ﬁeld and boosting the rooms, which was originally partitioned as the Haussmann model. Today, the lines block separating the room, structuring the volumes. The cornices have been preserved and the ﬁreplace was integrated in a spare ribbon linking the living room and the kitchen. The spaces are dotted by blue bottom conferring to the apartment a smooth homogeneity.
