Île-de-France
What to know before you build
A new house requires planning permission (permis de construire). For a single-family house, the standard processing time is two months from the submission of a complete application; it is longer near a historic monument or in a protected area.
Above 150 m² of floor area (surface de plancher), the project must be drawn up by an architect. In every case, we prepare the permit application with you and build to your architect's plans or to your own brief.
Since 2022, new houses have had to meet the RE2020 environmental regulation: insulation, airtightness, low-carbon heating. An air-to-water heat pump combined with underfloor heating is one of the common solutions.
Many municipalities in Île-de-France are exposed to the shrinking and swelling of clay soils. In these areas, the law requires a geotechnical study, and it is this study that sets the type of foundations: strip footings or a raft.
