All in 1 S.à r.l. is a construction company based in Roost - Mersch. We plan and deliver interior fit-out, renovation, drywall, bathrooms, flooring, ceiling systems and outdoor works across the whole of Luxembourg.
We're a hands-on team, our own people, our own tools, our own responsibility. No overseas subcontractors, no shifting blame. When something needs sorting after handover, the same people come back.
We work for private clients, developers, property managers, architects and companies. Projects range from a single bathroom refurbishment to full turnkey fit-outs of apartments and family homes.
What's important to us: a written fixed price, a confirmed date, a clean site, and quality that still looks right years later. That's how building in Luxembourg should work.
