Sustainable renovation · Belgium

From floor to roof,
with what
the earth gives.

Bio-based insulation, sprayed concrete, compressed earth bricks. Ancient techniques, living materials.

Family

Father and son. Two generations of craft, one shared passion.

Materials

Lime, hemp, straw, raw clay. Nothing that poisons.

Area

Wallonia and surroundings. Interventions possible across Belgium.

The approach

Renovating with materials that breathe.

A family passionate about quality work, we intervene in the ecological renovation of old and contemporary buildings. Lime, hemp, straw, raw clay: materials that regulate, that last, that don't poison.

Every project is an opportunity to pass on: the gestures, the choices, the materials.
