Benchmark for judging their offers: a house costs €2,500 to €4,000/m² excluding land and VAT, i.e. €375,000 to €600,000 for 150 m².
- Reference price: €2,500 to €4,000/m² excluding land and VAT; turnkey house €2,500 to €3,800/m²
- Response time: 3 companies covering your area contact you within 48 working hours
- 3% VAT: the company files the approval request before the works and you countersign it (quotes of at least €3,000 excluding VAT)
- Firm quote: requires an identified plot (PAG, PAP, soil, connections); without a plot you get an estimate
- Common exclusions: outdoor works, kitchen, painting, utility connections, municipal charges, soil survey
- Payment: against verified site milestones, never ahead of progress
Extending rather than building?
For an extension or an extra storey on an existing house, the request goes to companies specialised in extensions.
What a house construction quote must contain
A usable construction quote describes the house item by item, lists what is excluded and sets out the schedule, the payment plan and the insurance; an overall price on one page makes comparison impossible.
| Item | What must be written | The trap |
|---|---|---|
| Specification | Materials, insulation thicknesses, windows, heating and ventilation system | « According to the builder’s standard », with no detail |
| Floor areas | Living area and built area, with the calculation method | A price per m² based on a different area from the competitor’s |
| Exclusions | Explicit list of items not included | Items discovered after signing, paid at full price |
| Price | Fixed or revisable price, revision index, validity period of the offer | Uncapped revision over the whole build |
| Payment | Milestone schedule (foundations, shell, roof, finishes) | Deposits that run ahead of actual progress |
| Timeline | Start date, duration, delay penalties | « Indicative timeline », no commitment |
| Company | Business permit number, insurance certificate, Luxembourg VAT number | Foreign company without a Luxembourg VAT number: no 3% VAT |
Comparing 3 construction quotes on the same scope
Compare the specifications before the totals: bring the three quotes onto the same scope by adding to each the price of the items it excludes, then compare the price per m², the timeline, the payment schedule and the insurance.
The same brief for everyone
Floor area, number of rooms, finish level, heating: send the same description to all three companies.
An included / excluded table
One row per item, one column per quote; price every missing item to get three comparable totals.
Price per m² on the same area
Divide each corrected total by the same living area, then place it within the €2,500 to €4,000/m² range.
The terms, not just the price
Timeline and penalties, payment milestones, revision clause, insurance: when prices are close, these decide. To judge an announced timeline, see the usual duration of each construction phase.
The table of items often excluded from a « turnkey » offer and the 5 checks for choosing a builder are covered in our guide to turnkey house builders.
Reference prices for judging a construction quote
In Luxembourg, building costs €2,500 to €4,000/m² excluding land and VAT, and a turnkey house €2,500 to €3,800/m²: a quote well below probably leaves items out, a quote above must justify what it provides.
| For a 150 m² house | Range excluding VAT |
|---|---|
| Construction (architect + trades, or general contractor) | €375,000 – 600,000 |
| Turnkey house | €375,000 – 570,000 |
| Architect fees (if not included) | 8 – 15% of the construction cost |
| Utility connections | €6,000 – 15,000 |

3% or 17% VAT: what your quote must show
A construction quote for your main residence can be invoiced at 3% instead of 17%, but only if the company obtains AED approval before the works; without approval it invoices 17% and you claim the refund afterwards.
- Still at 17%: architect and engineer fees, fitted kitchen, furniture, outdoor works (except direct access).
- Cap: €50,000 of benefit per dwelling, which corresponds to about €357,000 of works excluding VAT; beyond that, the excess is taxed at 17%.
- Threshold: direct application covers quotes of at least €3,000 excluding VAT; below that, the refund procedure applies.
Procedure, forms and limitation periods: see our guide to 3% VAT.

Three comparable quotes, no obligation
Free for you: renov.lu is paid by its partner companies, never through a commission on your works. Three quotes: enough to compare prices without your phone ringing all week.
Frequently asked questions about construction quotes
How many quotes should I get to build a house?
Three quotes are enough if they answer the same brief: beyond that, comparison becomes hard to manage. Bring them onto the same scope by pricing the excluded items, then compare price per m², timeline, payment schedule and insurance. On renov.lu, your request goes to 3 construction companies: professionals established in Luxembourg whose business permit has been checked. You compare without being swamped with calls, free and without obligation, usually with a reply within 48 working hours.
Can I get a construction quote before I have a plot?
Yes, but you will get an estimate, not a firm price: foundations, utility connections and sometimes the shape of the house depend on the plot, its soil and the municipality’s PAG and PAP rules. An estimate without a plot helps size the budget and the loan; the firm quote comes once the plot is identified.
Is a construction quote free, and does it commit me to anything?
The request on renov.lu is free and commits you to nothing: you only sign with the company of your choice, or with none. The quote binds the company during its validity period; check that period and the price revision clause before comparing it with the others.
Why does my construction quote show 17% VAT instead of 3%?
Either the company has not yet obtained AED approval, which it must request before the works and you countersign, or the items concerned are excluded from the 3% rate: architect fees, fitted kitchen, outdoor works. Beyond €50,000 of benefit per dwelling, the excess is also taxed at 17%.
Can a construction quote be revised after signing?
Yes if the contract provides for a revisable price, usually indexed to a construction price index such as STATEC’s, which rose 2.6% year on year in April 2026. Have the index, the revision frequency and a cap written down, or negotiate a fixed price for the duration of the works.
