Our vision
Prefabrication isn't a tool. It's a method.
Building sustainably means first building intelligently.
Forget the classic building site: hazards, surprises, schedules that stretch.
We pilot the entire chain — studies, design, factory production, delivery, installation — controlled at every stage. The result: buildings delivered on time, a controlled budget, an asset that keeps its promises.
An off‑site specialist since 1960, SOLID is a company of the FEHR group. We combine the industrial expertise of prefabrication with the rigour of a developer-integrator.
Our principles
One method, three convictions
Secure early
Structural decisions are made early, where risk is controllable.
Standardise
Industrial repeatability in service of quality and cost.
Prefabricate
Build in the factory what the site can't guarantee.
