Blvd Auriol, Paris 13

The rationale for prefabrication supported by the project mixes two complementary materials. Wood as support structure and the assembly of precast concrete architectural elements for wrapping. The structural frame is defined by the spacing of the shear walls which corresponds to both traditional spans with regard to the constructive principle adopted and the width of a living room type A or B. The wood material and its interfaces with a mineral material thus become project generators.

The plot located at 90 boulevard Vincent Auriol in Paris 13th will accommodate 135 homes and a school. The projected and submitted building here acts as a link and transition between the site of the existing adjoining building and the site of the projected new building. It is an extension and not an autonomous building. It is in addition to complete an already constructed complex. It is positioned back from the street and maintains a landscape line at its feet. In plan, a slight shift within the volume was made to take a step back from the school and create a street side extension. The future project is set up on a soil, within an ecosystem in order to offer new perspectives of life. It also appears as a hyphen to a new language.
The rationale for prefabrication supported by the project mixes two complementary materials. Wood as a supporting structure and the assembly of architectural elements in prefabricated concrete for wrapping. The structural frame is defined by the spacing of the shear walls, which corresponds to both traditional spans with regard to the constructive principle adopted as well as to the width of a type A or B living room. The principle of organisation of a current floor plan orients the plane along the common axis. It runs along the depth of the building while forming regular recesses that create a repetition of full/empty which gradually shift and intercalate. The intermediate floors are also made of wood forming horizontal diaphragms between the column lines. The underside of these slats remains visible so as to make apparent the materiality in the homes. The wood material and its interfaces with a mineral material thus become project generators. It is the interface between these two materials that particularly interests us. Each questioning its limits and its own and/or combined characteristics.
The typologies of developed housing make sense in their specificities as well as in the operation as a whole. The size of housing space is related to the size of the urban development. The proposed typologies are diversified. They meet the needs of large family housing with 48% of T3, 74% of T3 and more, and 26% of T4 and more.
In terms of living surface area, the plan offers comfortable accommodations whose spatial characteristics are:
. The compactness of the floor plan
. The positioning of angles generate housing with double or triple orientations.
. The structural framework within the housing arrangement and the parts that constitute it.
. Day and night spaces are differentiated hierarchically to create a dynamic plan.
. Service spaces are grouped together to form a backbone.
. Outdoor spaces as an extension of the living space.
The living rooms are largely glazed with mixed joinery wood/aluminum consisting of either three French doors opening above the breast wall or four windows consisting of two fixed and two opening the full height for large frames overlooking the loggias. The glazed parts fit between two walls creating an opening over the entire width of the living room. The blinds are selected and positioned according to their degree of opening, allowing the benefit ranging from a simple veil of intimacy to total concealment. A hollowed loggia regularly accentuates the desire to extend the interior space towards the outside. Loggias are structurally independent elements. A parapet made of pre-cast openwork concrete completes the continuity of the floor of the loggia. Where our living rooms do not have a loggia, they are treated with a fixed window which follows the moulding of the parapet to the full. An attic retreat on the garden side makes possible to provide generous terraces to the dwellings. This attic plan alternates accessible terrace and planted spaces.
The roof is green and inaccessible, except for maintenance. The roof houses generous planted areas which by a pattern of the topsoil thickness provides a variation of plant seedlings. The plant palette shows off the melliferous and flowering plants. This selection reduces maintenance with a minimum of green waste, low rooting and resistance to drought while providing a diversified and quality food resource for pollinating insects including wild bees.
