An equator. A double bay, three beams between dividing walls. Two rooms facing south, towards the street. Two pairs of double windows, pattern of vertical strips under the windows. A dark floor, wide boards between flush battens. In the living room, traces of a wall, alcove from another time. Wood paneling interrupted by a door frame; towards the room, glass handle, extinct fashion, opening towards the fireplace and its trumeau, gallant scene and mirror dominating an entablature with two smooth honey-colored columns. A hidden door dissecting the wood paneling, a small hall. Staggered 10 x 10 ceramic tiles, green clay color on the floor, white on the walls, smooth paint, white ceramic tiles, three different textures. Back to the living room by another hidden door: vertically striped paneling, folded at the angle over the woodwork. Cutting of the partition wall, vanishing point towards the north window, a light surface, repetition of the striped pattern. Party wall and paneling stretching from the living room towards the entrance, crossing of the equator to the north, depth of the apartment 10.10 meters, perceivable from the entrance door. Welcome threshold. Second vanishing point, apartment width 7.07 meters. Pine boarding over existing floor. Six boards extended between party walls. A piece of linear furniture, densification towards the courtyard, entry, storage, and light source. Two linked spaces and one large window. Diagonal glance, splayed window. Smooth panels from closed shutters, continuity of a folded plane, stripes under the window. A sliding door as symmetrical axis. Occasionally restored division. Door at the end of the wardrobe opening onto 10x10 ceramic blue floor, white walls, smooth paint, white ceramic tiles, three textures. Back to the entrance. A red and black patterned carpet, colors from the vieux Bayonne, 20 x 20 ceramic tiles, setting of culinary preparations. A piece of furniture that sits, a little higher than the eyeline, support for indirect light. Birch niche inserted in white, a horizontal plane, bathed in light. Two vanishing points into the hall: recess framed under the beam, facing south; wood paneling in the background, continuity between the two sides of the equator.
