Transform a building. Preserve its coherence.
A complete renovation coordinated from A to Z, with a single point of contact for decisions, trades and finishes.
Far more than a succession of separate trades.
We think about the whole site: volumes, technical systems, envelope, finishes and exteriors.
This overview avoids inconsistencies between work packages, helps anticipate constraints earlier and keeps a clear direction throughout the project.
Everything that makes up a complete renovation.
Structural transformation
Demolition, masonry, openings, structural work and preparation of the new volumes.
Building technical systems
Electrics, plumbing, heating, ventilation, drainage and hot water production.
Interior fit-out
Partitions, plastering, flooring, kitchens, bathrooms, joinery, paint and finishes.
Envelope & exteriors
Roofing, waterproofing, insulation, façades, terraces, driveways, garden, lawn and pool area.
A renovation that takes months? Follow it online.
A complete renovation runs over several months. From your private area, you see where every work package stands, this week's photos, the schedule and quotes to approve — without having to chase for updates.
- Progress package by package
- Dated photos and reports
- Schedule of upcoming interventions
- Additional quotes approved in one click
The same level of rigour, down to every detail.
For an exceptional property, junctions, materials and continuity between interior and exterior matter as much as the major work packages. Our role is to maintain that coherence.
- Single point of contact
- Coordination of tradespeople and suppliers
- Protection of spaces and materials
- Careful quality control of finishes
