The project is located on a land with complex relief the Château Rouge sector in Paris 18, which comprises approximately 300 plots and more than 450 buildings. The operation consists in the major rehabilitation of the building at 5 rue Myrha and its extension by demolishing the buildings at 7 rue Myrha and 32 rue Affre and a new corner construction, which brings together 14 collective social housing and a shop on the ground floor. Bringing the plots together makes possible to have a larger facade developed on the street, often necessary for commercial ground floors, and to work on the treatment at the corner of rue Myrha and rue Affre.
Existing-new junction Significant work to enhance the existing facade has been carried out: restoration of the wooden structures, replacement of the identical coating, identical replacement of the exterior shutters and wooden joinery, renovation of the railings on the facade on the Myhra Street side. To emphasize the continuity between the existing building and its new extension, a steel profile marks the heights of the floors and extends the cornices of the building at 5 rue Myra. These horizontal lines structure the facade alternating rectangular mineral panels of storey height and vertical joinery surmounted by a mineral transom. This façade system interrupts it at the level of the old building at 32 rue Affre.
The trace of the existing plot In order to preserve the trace of the old plot, the architectural expression of this facade is modified. A metal cladding of the same nature as the basement is pierced with a large sliding window at each level. This modification of the facade allows a smoother transition with the facade of the neighboring building.
The angle treatment To mark the corner of the building and offer the living rooms a framed view of the Sacré Coeur, a large window is provided in the angle. A slight offset movement between the levels dramatizes the angle and underlines the superposition of the floors.
Housing In order to optimize the floor space of the apartments and the organization of the building, the existing staircase has been removed in favor of a vertical circulation core located in the new building and common to both buildings. Each floor landing is naturally lit on the courtyard and serves 3 apartments per level. The dwellings are either crossing or in a corner situation.
The facade The rehabilitated building consists of a street facade in stones covered with plaster from the ground floor to the 3rd floor, and in bricks also covered with plaster on the 4th floor. The very degraded facade coating is restored to the same using a whitewash plaster. All of the existing moldings (window frames, bands and cornices) are restored identically by molding. The rear facade is made of half-timbered with filling covered with a coating and paint. The coatings are taken up with a finish in mineral paint in a light tone.
