Compare terrace renovation companies in Luxembourg for wooden decks, composite decking, natural stone and full rebuilds with foundation. A wooden terrace in pine or larch runs €150 to €300 per m², composite decking €200 to €400 per m², and stone (bluestone, granite, Luxembourg sandstone) €250 to €500 per m². A full rebuild of a 30 m² terrace with new foundation and drainage sits around €10 000 and up. A building permit is required above 20 m² of added surface, drainage must respect the Règlement Général de Voirie, and boundary distances to the neighbour are set by the PAG. Ask for the soil-drainage plan before tiles leave the yard.

- Natural stone terrace (bluestone, granite, sandstone)
- Foundation and drainage rebuild
- Replacement of existing deck boards
- Pergola and railing integration
How to choose
- Drainage plan in the quote — A serious terrace contractor shows the drainage slope (1 to 2 percent minimum), gully placement and connection point to the rainwater network on the quote. Without it, water sits, seeps, and cracks the slab within two winters.
- FSC or PEFC wood certification — For tropical hardwoods like ipe or cumaru, insist on FSC/PEFC certification on the delivery note. Non-certified batches carry legal and reputational risk and are often lower-grade than advertised — rot appears in half the expected time.
- Building-permit guidance — Adding or enlarging a terrace by more than 20 m² of footprint generally requires a permis de bâtir from the commune under the PAG. A capable contractor flags this at the first site visit and either files the application or connects you with an architect.
- Boundary distance check — Luxembourg communes set minimum distances to the neighbour's property line under their PAG — typically 1 to 3 metres for a raised terrace. A contractor who skips this check leaves you exposed to a demolition order at the neighbour's complaint.

Frequently asked questions
How much does a terrace cost per m² in Luxembourg?
Wooden deck in pine or larch €150 to €300 per m² installed, composite decking €200 to €400 per m², natural stone €250 to €500 per m². A full rebuild on 30 m² with new foundation and drainage runs around €10 000 and up. Heritage sandstone or bluestone pushes past €600 per m².
Why does drainage matter so much on a terrace?
Standing water cycles through freeze-thaw 20 to 30 times per Luxembourg winter. Each cycle expands micro-cracks in the slab and the waterproofing membrane; after 2 to 3 winters of pooling, leaks into the rooms below are common. A €3 000 drainage correction is cheaper than a €15 000 waterproofing redo plus interior repair.
Do I need a building permit for my terrace?
Above 20 m² of added footprint, yes. A raised terrace, a pergola or a modification to the building envelope also usually triggers a permis de bâtir. Rules vary by commune under the PAG — ask your contractor for a pre-filing check or call the commune's service urbanisme before signing.
