After almost three years of a real estate crisis caused by the outbreak of credit rates, “You have to be able to build housing marketed at affordable prices»»insists Jean-Philippe Dugoin-Clément, president of Grand Paris Aménagement. Gold “Housing is one of the sectors where productivity gains have been the lowest in recent decades. Particularly because we stack the standards (construction, environmental, etc.), in this country ”he regrets. It was to encourage promoters and other stakeholders in real estate construction that the developer launched, in January, a competition aimed at dividing the production costs by two. The final objective being to build housing, costing their buyers halfway or their tenants.

Among the 23 groups of promoters, architects and design offices that applied, Grand Paris Aménagement selected five, presented at the MIPIM real estate show, this Wednesday, March 12, concerning programs of 50 to 70 dwellings. For example, the “Métamorphose” project, carried out by the continental land promoter, the Architects Agency Moon and the Immobilière Social 3F, provides for the construction of small buildings, from one or two floors to the maximum, in relaxed areas, where the demand and the supply of housing is balanced. It is based on the Hors -site constructionproduced by the Sybois industrialist. Characterized by the manufacturing in factories of elements of a building which will then be assembled on the site, this construction mode allows faster production, at a lower cost and of good quality. The specifications of the command competition “Do not cut off on quality”specifies in this regard Jean-Philippe Dugoin-Clément.

Evolutionary habitat

The “Omotenashi” project works on the evolutionary nature of housing which it aims to build in the first and second Parisian crowns, very tense areas. Carried by the promoter Hibana, the architectural firm ECDM and the specialists in the rector and Pobi construction site, it is inspired by the “Ryokan”, traditional Japanese inns including the mobile partitions make it possible to regularly redefine their spaces and their uses.

Another project, that defended by In’li, a subsidiary of intermediate housing housing housing, and the architectural agency Martin Duplatier, concerns both new construction and rehabilitation of existing housing. It is a question of allowing the inhabitants to remain in the same building during the different stages of their life, for example when the arrival of a first, then of a second child. This, making the building “Legally and technically evolving”and using SCI (Civil real estate companies). These make it possible to finance major real estate projects, by pooling the purchase costs of goods between partners.

Building permits deposited by the end of the year

“Surprisingly, less than a quarter of the candidates envisages derogations from the standards in force, stressing that Many can be done on law and constant standards»»notes Jean-Philippe Dugoin-Clément. Applicants who will benefit from land provided by Grand Paris Aménagement, who will also help them obtain the derogations necessary for the implementation of their projects, so that building permits can be submitted by the end of the year.
