On the border between the new Creation district and the Parc des Chantiers, Boulevard Léon Bureau occupies a strategic position and develops a skyline made up of horizontality and emergence, symbols of the île de Nantes.
Backing onto a suburban house with discreet moldings and slightly deviating from the DY10 blockhaus, a converted vestige of the Second World War, our project will forge a horizontal link between these two iconic constructions and will affirm its difference through a vertical and light emergence. This is where our dual ambition lies, that of creating a strong architecture combined with soft insertion.

On the boulevard side, the ground floor is mainly occupied by a space of approximately 170m² which will be dedicated to a commercial or catering activity. This program will complete and continue the series of small shops and restaurants already present on the islet. Between the ground floor, set back from the Harmonie Mutuelle building and the opaque one of DY10 Blockhaus, the activities of our basement are an essential asset for the liveliness of the boulevard.

The facades of the volume resting on the concrete basement are made of a thick colonnade of hardwood painted in ocher color. This horizontal and vertical colonnade organizes all the modenature of the facades. The long facades consist of 5 bays. Thus in a bay, we go from 6 modules to 5 modules and 3 modules in last level. This decrease in the number of modules associated with the increase in the heights of the modules gives an impression of progression towards the sky, giving the building a slenderness and natural elegance.

These elements are not structural and are separate from the supporting structure of the building. The infill elements of these modules are either full-height glazing, or powder-coated aluminum panels in shadow gray, thus adopting the color perceived by the glazing during the day.

Mixed wood-concrete structure combining the advantages of concrete slabs and the prefabrication of wood-frame walls, our project is part of a chosen durability to which the client was convinced. All the dividing lines for the housing units are made of plaster acoustic partitions, the timber frame and framework of the semi-curtain mantle walls are in French spruce, the wooden thorns and cornices on the facade are in French Douglas fir painted in the factory on 6 sides with decennial warranty . In addition, the post-slab structure (without beam fallout) allows significant adaptability of the project. One can imagine the grouping of several apartments to increase their surfaces without structural work.

Concerning the blackout system, a system of external blinds with orientable slats in dark lacquered aluminum will be installed for the bedrooms and masked by a painted hardwood lintel identical to the colonnade of the facades. Beyond this function, this lintel, present in front of all the bays (including those entirely full) emphasizes the modenature of the facades and asserts a little more the horizontals while reducing their shadow. The hierarchy between masses and shadows is organized to offer a subtle facade, with soft and strong architecture.
