Guillaume Bionier, 48, from Vaas in Sarthe, has founded GB Aménagement in a relay workshop at the Loirécopark site in Aubigné-Racan, owned by the Sud Sarthe community of communes. The business converts commercial and leisure vehicles, from ludospaces to vans, 4x4s and campervans. Bionier carries out bespoke work including panelling walls and floors, building and installing storage for tools and professional equipment, and full interior fit-outs with windows, pop-top roofs, insulation, water tanks and photovoltaic systems with standalone batteries. For private customers, three trim levels are offered: base, intermediate and luxury. The project received €8,000 in support from Initiative Sarthe and the Sud Sarthe community of communes. A basic conversion takes around ten days, and Bionier advises ordering now for projects planned for April 2027.
