The project

What the brief demanded.

A 280 m² energy-positive villa designed for a Franco-Swiss client with Swiss-standard expectations. The project targets positive energy performance within restrained, technologically advanced contemporary architecture.

The structure rests on a suspended concrete slab with facades in high-performance insulating blocks. The roof integrates a building-integrated photovoltaic system that maximises production while keeping a homogeneous architectural appearance.

The whole energy system combines geothermal heating, 40 kWp of solar panels, an earth-air heat exchanger and high-efficiency balanced ventilation to guarantee a positive annual energy balance.

Proof of mastery

What the site put in our way.

5 major constraints, and how each was resolved on site. This, not the photography, is how a general contractor is judged.

  1. 01

    Overlapping French and Swiss standards — dual validation to RE2020 and SIA 380/1.

  2. 02

    Building-integrated solar roof — waterproofing and electrical work coordinated in a single phase.

  3. 03

    Groundwater geothermal system at 6 m — drilling supervised by the environmental authority (DREAL) with piezometric monitoring.

  4. 04

    Strict contractual deadline — reverse scheduling from the handover date.

  5. 05

    Residential site access — logistics agreed with the local town hall.
