Impact report
Societal impact
La Casa delivers high-quality housing in high-demand areas
Creating housing by renovating existing buildings

+8 homes created on average, without land artificialization - a total of +526 homes created since 2017.
Improving energy performance
Our renovations significantly improve energy performance:
DPE E before works → DPE C after works (on average)
Facilitating mobility
All our Casas are located within 1 km of public transport:
→ easier access to jobs, education, and services
→ reduced reliance on cars
Complying with rent control
Housing aligned with the market and compliant with rent control:
→ €690 on average (excluding charges and services) for ~23 m² per housemate in the Paris region
Optimizing space usage
We densify intelligently without compromising comfort.
Each resident has a private room of around 12 sqm with an ensuite bathroom, complemented by 11 sqm of shared spaces (kitchen, living room, laundry, outdoor areas), for a total of 23 sqm per housemate on average.

Environmental impact
Our shared housing model reduces the carbon footprint of housing
Reducing emissions linked to housing production
Renovating an existing home instead of building new can reduce up to -50% of carbon emissions.
Sharing equipment between 12 housemates, rather than owning it individually, reduces furniture-related emissions by 47%.
→ In total: 1,997 tons of CO₂ avoided in 2025 thanks to our model.
Reducing emissions from property operations
Living in a Casa saves 20% of energy (electricity and gas) compared to an individual studio.
→ equivalent to -133 tons of CO₂ avoided in 2025 across the entire portfolio
