Text description provided by the architects. The project is located north of the macro-lot B3, on the trapeze, the Zac Seguin Rives de Seine in Boulogne-Billancourt. The 73 units of the operation performed for Icade Promotion housing were sold 54 units as VEFA to Foncière logements and 19 units to Immovalor.
Depending on the method used in the ZAC, the agency Philippe Dubus Architects has been appointed by all stakeholders of the ZAC, the SAEM Val de Seine, developer of the old Renault site, the group sponsors DBS, the City of Boulogne-Billancourt and the team Lispsky and Rollet, architects coordinators of the macro-lot ; in order to work with six teams selected on the macro-lot B3 and design a project of 73 units on the lot B3B.
The design and development of the project are the result of numerous discussions among all stakeholders, Town, urban planner, owner, and workshops organized by the agency Lispsky and Rollet with the six teams of architects of the macro-lot. Templates, the volume and location of buildings are strongly constrained by the PLU, the dialing plan urban and SHON announced by Lispsky and Rollet after the consultation organized by SAEM Val de Seine.
The project is based on the requirements of the architectural and landscape architects coordinators and SAEM :
- Change of architectural writing projects macro-lot B3 from west to east, from the massive in the west to lightness in the east.
- Use of raw materials, concrete, aluminum, galvanized steel, wood, predominantly in shades of gray.
- Development of private outdoor spaces as an extension of each unit through balconies ropy.
- Treatment vegetated roofs and dressing shrines techniques.
The project is divided into three blocks: on the north, a building (7 levels) facing the street, with the alignment on the new road, a central pin (4 levels) in the heart of island, which is articulated with a « turret » posed in the gardens, punctuating the landscape inside of the island. Each building is set on a common principle : The main facades are lightweight, they are composed of large full height glass frame in natural anodized aluminum and polycarbonate cladding panels "Ice" for outer insulation.
These facades take place in a raw concrete skeleton self-compacting: plinth at the bottom, perpendicular gable to the facades and vegetated roof terrace at the top. A precast concrete walkway 80 cm wide spins along light fronts, it allows maintenance, provides protection to fire and sunlight, in addition to awnings that fit all chassis. In the heart of island, platforms protruding piggyback on these corridors, providing generous 15m ² to 30m ² of living space outside each unit, in cantilever over the gardens. The exterior soffit panels of polished aluminum fits up facades to capture the light and providing a sky to each terrace. Glass railings that meanders across corridors accentuate crystalline expression of the project.
