Renovation budget in Luxembourg: how to estimate without surprises

The simple idea

A realistic budget is not built on “gut feeling”. It’s built from renovation level + technical trades + finishes.

Luxembourg price ranges (quick reference)

Typical per m² ranges depending on project scope:

• Light renovation: 250–750 €/m²
• Partial renovation: 750–1,250 €/m²
• Major renovation: 1,150–3,000 €/m²

Simple example: A 70 m² apartment under a “partial renovation” often falls within €52,500–€87,500 (excluding structural surprises). This is not a quote, just a benchmark.

7 cost drivers (and how to control them)

1. Demolition / disposal: The more you remove, the more you pay (and the more hidden issues you may uncover).
2. Surface preparation (walls/ceilings/floors): Often the real “hidden” cost.
3. Drywall/Placo + ceilings: Depends on acoustic/fire requirements, linings, thickness.
4. Electrical: distribution board, wiring, outlets, lighting, kitchen loads.
5. Plumbing / drainage: Keeping water and drainage points in the same place often saves a lot.
6. Floors: levelling (ragréage) + installation + skirting + thresholds/transition strips.
7. Bathroom: usually the most expensive room per m² (waterproofing + fixtures + fittings).

What you must demand in a quote (otherwise you compare apples to oranges)

• Measured quantities (m² / linear meters) and assumptions (surface condition).
• Clear included/excluded items (protection, disposal, touch-ups, final cleaning).
• Material quality/brands (at least the “range/grade”).
• A phased schedule, not just one final date.

Possible grants

Depending on your case, an “improvement” grant may exist covering up to 40% of the HTVA invoice amount (conditions apply).
