Density and lightness are the characteristic qualities of Lot D, designed by architects Cédric Petitdidier and Vincent Prioux. With 109 apartments, making it the largest public housing development in the Boucicaut ZAC1, the building articulates around three independent staircases. In total, it offers 24 government-sponsored and 77 rent-controlled apartments (€17.70/sqm), and 8 residential units for people with disabilities. The project is headed by Nexity, appointed project manager by developer CARAC and public housing agency Élogie. Entirely clad in bricks, this project marks the completion of the surrounding ecodristrict, offering a reinterpretation of Paris courtyards that connects Rue des Cévennes with the park that lies in the centre of the district.
The two architects, Cédric Petitdidier and Vincent Prioux, imagined this walkway to favour gentle circulation on the lot, which was envisioned from the very beginning as a pedestrian oasis and a pioneer biodiversity programme. This initiative in the heart of the 15th arrondissement hosts a number of installations for the conservation of fauna and flora.
 

Description of the project by Cédric Petitdidier y Vincent Prioux

“Designing apartment buildings in such a dense city as Paris necessarily implies looking for space planning solutions, to minimise the imposition of close proximity to neighbours on the one hand, and to guarantee everyone feels comfortable sharing the public space on the other. These two dimensions are the key to striking a balance between the quality of the accommodation and the contribution of the project to the district’s pedestrianisation.”

Cédric Petitdidier and Vincent Prioux

 
Reasoned density.-

The design of the project offering 109 apartments within the Boucicaut ZAC relies on two solutions to lessen the impact of the project’s high density:

Stretching across the project is a courtyard, surrounded by four facades (windows open mainly onto kitchens, bedrooms and a few bathrooms), much like traditional Paris courtyards. This space is as much a public space for pedestrians by day as a garden serving each entrance on the lot. Its dimensions and proportions provide excellent ventilation and allow sunlight to flood the courtyard all day long.

The bulk of the programme is contained within the boundaries set by two strips running perpendicular to Rue des Cévennes and materialised by two solid brick buildings, consistent with the area’s architectural vocabulary. The two strips are linked together at both ends by two suspended buildings, one facing the street, the other facing the park, creating clusters of interlocking blocks: the clouds.

Loggias and terraces.-

The distribution of the apartments inside the strip and cloud buildings gives them distinct and specific qualities, particularly evidenced by their exteriors:

The strip buildings are designed strictly as orthogonal shapes, each delineating a frame enclosing the apartments and their adjoining loggias or running balconies overlooking Rue des Cévennes. The rectangular layout means all corners can be used, (including those on the courtyard’s side), providing a large number of apartments with adequate visibility and orientation.

The design of the central buildings is reminiscent of stepped buildings, where each floor is set back from the floor below, providing space for a terrace. Slightly set back from the strip buildings, the clouds have been carved to create recesses, opening onto wide vistas, without compromising privacy.

Cédric Petitdidier and Vincent Prioux, born in 1978, they first met in the banks of the school of architecture. Graduates in the year 2002. Then they collaborate in different studies like Atelier Seraji, in the case of Cédric Petitdidier and Lipsky + Rollet in the case of Vincent Prioux. They created the studio PetitdidierPrioux after joining in 2004, when they won the contest "Archi'nova - comment habiterez-vous demain?" Launched by Alliade group. Then they build 55 homes in one of the plots of the Duchère ZAC (Lyon), where they practice a new type of housing units stacked: "maisons-plateaux" The invitation, in 2007, from the Ministry of Education to participate in the competition for the remodeling and extension of the Mounira palace, the IFAO headquarters in Cairo, is an experience that defines its desire to design the public endowments and the passion of the work on the existing city and the memory of the places.
