Planning to renovate your home in Luxembourg but unsure which strategy to adopt? Renovating everything in one go or proceeding room by room are two radically different approaches, with very distinct financial, practical, and family implications.
The Two Approaches in Brief
A complete renovation involves renovating everything in a single phase: insulation, heating, roof, electrics, plumbing, and finishes. It’s the all-encompassing project that disrupts everything at once but for a limited period.
Room-by-room renovation allows you to progress gradually: you renovate the bathroom this year, the kitchen the following year, according to your budget and priorities.
Comparison Table
| Criterion | Complete Renovation | Room by Room |
|---|---|---|
| Duration of works | 3 to 9 months at once | 2 to 10 years |
| Immediate budget | €50,000 to €200,000+ | €5,000 to €30,000/year |
| Klimabonus grants | Optimised (single application) | Possible but fragmented |
| Disruption to daily life | High but short | Light but prolonged |
| Consistency of result | Excellent | Variable over the years |
Complete Renovation: When It’s the Right Option
You’ve just bought a property to renovate. This is the ideal time: you’re not living there yet, so you can let the tradespeople work without constraints.
Your home is in poor overall condition. When the insulation is failing, the electrics are outdated, and the plumbing needs replacing, it makes sense to tackle everything together.
You want to maximise Klimabonus grants. A single application for a comprehensive renovation simplifies the process and can cover up to 50% of certain works.
Cost of a Complete Renovation (150m² house)
| Work Item | Estimated Cost |
|---|---|
| Insulation (walls, loft, floor) | €25,000 to €45,000 |
| New boiler or heat pump | €12,000 to €25,000 |
| Electrical rewiring | €8,000 to €15,000 |
| Plumbing and bathroom | €8,000 to €20,000 |
| Windows (10 units) | €6,000 to €15,000 |
| Kitchen | €10,000 to €30,000 |
| Finishes (painting, flooring) | €8,000 to €20,000 |
| Total estimated | €77,000 to €170,000 |
Room-by-Room Renovation: When It’s Preferable
Your annual budget is limited. You can’t mobilise €100,000 at once but can manage €10,000 to €20,000 per year.
You’re living in the property. Renovating one room at a time causes less disruption to daily life.
Some works are urgent. A leak, a boiler at end of life: you intervene where necessary.
The Ideal Order for Room-by-Room Renovation
- Roof and waterproofing (protects everything else)
- Insulation and heating (maximum energy impact)
- Electrics and plumbing (before finishes)
- Windows and joinery
- Kitchen and bathrooms
- Finishes (painting, flooring, decoration)

FAQ
Can you combine Klimabonus grants for a phased renovation?
Yes, you can submit several applications over several years. However, the rules may change, which represents a risk.
How long does a complete renovation project take?
For a house of 100 to 200m², allow 4 to 9 months depending on the scope of works and availability of tradespeople.
Do you need an architect for a complete renovation?
For works that modify the building’s structure, a registered architect is mandatory in Luxembourg. Below certain thresholds, it is recommended but not required.
