Description

The Impasse des Chevaliers project, located in Paris 20, is a social housing development for Habitat Social Français, designed by architect François Prinvault and executed by general contractor SNERCT. It consists of two buildings: a 2-storey structure covering 227 m² and a 4-storey building spanning 702 m², both situated on the Belleville hillside, with an 8-meter elevation difference across the site. The project aimed to achieve sustainable density in a densely populated area and posed significant challenges, especially since no lifting equipment could be used due to the location within an inhabited zone. To overcome this, 1,800 wooden components were manufactured, transported through a parking entrance, and assembled on-site within just 10 weeks.

Impact & Result

The project incorporated 103 m³ of wood and 80 m³ of biobased insulation, resulting in 96 tons of CO2 stored. Additionally, 7.6 kWp of photovoltaic panels were installed. The wooden skeleton of the buildings was constructed in just two weeks for the 2-storey building and two months for the 4-storey building. This efficient construction timeline allowed the contractor to better organize the job site and streamline logistics for all the materials. The LEAN method was utilized to optimize the project’s organization and workflow, ensuring a smooth and efficient process throughout.

Solution Spotlight

Ki Wood develops and manufactures a wooden construction system. A principle of Japanese origin that involves assembling glued-laminated timber posts and beams with invisible steel connectors to create the structure of buildings. The solution meets the challenges of creating low-carbon buildings, with an innovative solution that is manufactured off-site, is ultra-simple and quick to assemble, and requires no particular expertise on the part of the fitters.
