Raising housing, a solution that appeals to elected officials

Cours Emile-Zola in Villeurbanne (Rhône), seven floors and 24 social housing units will be built on one level above a commercial building. At 7 Rue Pasteur^e Two levels will be added to a 19th-century building in the Lyon district^e century. The metropolis of Lyon begins to rise: its vice-president for housing, Renaud Peyre (United Left), announced on Thursday, March 23, the creation of 250 to 300 social housing units in two years with this technique. “It allows us to be self-sufficient at a time when developers are canceling certain construction projects.”, he appreciates. If only social landlords are mobilized for the moment, with a small grant, the metropolis also intends to support private initiatives by experimenting with the area where the maximum heights will increase.

Beyond the example of Lyon, many French cities, land-scarce and subject to “zero net artificials” targets (including a 50% reduction in the rate of natural space consumption by 2030), are on the rise. Strasburg asked UpFactor, a company that specializes in identifying height potential, to To assess the possibilities in its territory: 16,500 buildings were identified thanks to the modeling software of existing buildings and authorized heights.

“The result will spread because the height deserves to be democratized: it allows the cooperatives to finance their energy renovation with the right to assign the operator; It creates housing without occupying land, Vice President for Habitat, ecologist Suzanne Brole claims. And it seems to have been well received: none of the high-rise building permits I signed in Strasbourg resulted in an appeal! »

The Metropolis of Nice also commissioned a study by UpFactor: “ 10% of shares will be increased, i.e. the potential to create 3850 residential units., cheers its vice-president, Anthony Borre (ex-Les Républicains). He turned to French building architects to be able to build a large area classified by UNESCO.

“Additional Tool”

within the metropolis, “The rise is a consensus, including for the opposition environmentalists and the national rally”, welcomes the chosen one. On the other hand, the municipal majority in Paris, which is developing its future local urban plan, is itself divided. In a 2014 study, the Atelier parisien d’urbanisme estimated that 10% of the buildings on the street could be subject to a height study. “In reality, the realization is much lower than these theoretical figures, but the height will certainly make it possible to produce 5,000 to 10,000 residential units, and that will be very good.”According to Jacques Baudrieu, deputy (PCF) responsible for the ecological transition of buildings, a fervent advocate of height. This is an additional tool. »
