Preserving the identity of the location
This project included ten residences of varying sizes, each with a private garden. The challenge of the project was to ‘adapt an old rural building to contemporary uses.’
The long house, a traditional building in the Ile-de-France region, was reincarnated for the modern-day world. The apartments are traversing and have floor-to-ceiling windows for extra light. The irregularly positioned openings in the façades allude to the modifications made over time to the initial design of the buildings – and keep a farm-like spirit too!
A reproducible system
The building system was rationalised and led to the design of a template for creating modules of 5 to 7 m in length and 2.7 m in height. This semi-prefabricated system had several advantages: the lightweight structures were easy to lift and transport, easy to store on site and quick to assemble.
GHG emission and energy efficiency
- Performance of the envelope: equivalent to a new BBC (low-energy house)
- GHG emission: 5 kg CO2e/m²/year
- Energy performance: 50 kWhPe/m²/year
- Design highlights
- Solar hot water
- Masonry stove
- Natural ventilation
