Conservatory budget in Luxembourg: compare the whole project
Published on 31 July 2026 · Verified on 19 September 2026 · The Mestravaux.lu team
We do not publish a local average without dated, comparable quotes. Define use and gather the work needed from design to finishes. The frame price is not the cost of a completed room.
The essentials in 30 seconds
- Equal area is insufficient: match use and performance.
- Separate structure, site preparation and interior fit-out.
- Make conditional work visible.
- Do not deduct unconfirmed support from funding.
Set budget boundaries
Specify dimensions, roof, openings, connection to the house and seasonal or integrated use. Identify finished flooring, lighting, heating and shading. Define which area a square-metre rate uses: external footprint and usable internal area differ.
| Matériau | Niveau | Prix par m² | Total pour 20 m² |
|---|---|---|---|
| Aluminium | Véranda d'été (non isolée) | 700 – 1 100 €/m² | 14 000 – 22 000 € |
| Aluminium | 4 saisons (isolée) | 1 200 – 1 900 €/m² | 24 000 – 38 000 € |
| Bois massif | 4 saisons (isolée) | 900 – 1 400 €/m² | 18 000 – 28 000 € |
| Mixte bois-aluminium | 4 saisons (isolée) | 1 300 – 2 000 €/m² | 26 000 – 40 000 € |
Fourchettes indicatives hors sol, chauffage et raccordements. Un toit rond ou une verrière complexe ajoute 10 à 20 %.
Compare materials at defined performance
Identify profiles, finishes, glazing and roof with whole-system performance and installation conditions. Do not automatically rank aluminium, timber and mixed construction by price. Triple glazing, flat roofing or thermal breaks alone do not establish comfort; compare a design for your use.
Add site and house work
AQC identifies the slab, foundations and junctions as sensitive design points. Request investigations, excavation, supports, façade junctions, rainwater and services as separate items. Distinguish included work from items awaiting assessment.
Budget comfort without blanket promises
Klima-Agence highlights shading in summer comfort. Price chosen measures alongside glazing and ventilation. For heated spaces request demand assessment and associated connections. Thermal improvements do not automatically establish fixed savings or construction grants.
Your project deserves an accurate estimate — it's free.
Request a quotePlan operation and repair
Request maintenance, cleaning access and availability of seals, hardware, motors and glazing. Separate component warranties, exclusions and installation. Aluminium is not maintenance-free; a warranty period does not establish service life.
Check the amount to fund
Add design, charged formalities, works, delivery, installation and finishes. Show taxes, options and exclusions. Agree payment, possible price revisions and approval of extras. Confirm the exact support scheme and eligibility; insulating glass alone does not establish Klimabonus entitlement.
Frequently asked questions
Why no average price?
No comparable local quote series establishes one; technical references do not prove prices.
Is a square-metre rate enough?
It can help after scope is aligned, but does not replace the total.
Is aluminium always cheapest?
No. Compare equivalent dimensions, finishes and performance.
Is a larger conservatory always cheaper per square metre?
No. Spans, access and supports can change costs; request both options.
Does one warranty cover everything equally?
Check components, installation, exclusions and the responsible contact.
