Why Install a Veranda in Luxembourg?
Installing a veranda in Luxembourg is a project that combines living space extension and property value enhancement. With cold winters and temperate summers, a well-designed veranda allows you to enjoy natural light while providing optimal thermal comfort. However, the budget to plan in 2026 depends on many factors: surface area, materials, finishes, and compliance with local regulations.
What Is the Average Budget for a Veranda in 2026?
The cost of a veranda in Luxembourg varies considerably. For a 20 m² surface, prices range between:
- 30,000 to 50,000 EUR for a PVC structure
- 40,000 to 65,000 EUR for a wooden structure
- 45,000 to 70,000 EUR for an aluminum structure
These amounts generally include foundations, frames, glazing, roofing, and installation, but exclude interior finishes and furniture. The cost per square meter is between 1,500 and 3,500 EUR.
Financial Aids Available in 2026: Klimabonus Wunnen
Since January 2026, the Klimabonus Wunnen program has replaced PRIMe House. It offers subsidies for energy renovation work, including verandas if they are considered an integral part of the dwelling. Key amounts are:
- Roof insulation (R ≥ 6 for sarking, R ≥ 7 for attics): up to 50% of costs, capped at 15,000 EUR
- Glazing replacement: 70 EUR per m² of replaced glazing area
- Installation of photovoltaic panels: up to 10,000 EUR (approx. 8,300 EUR for 10 kWp, maximum from 15 kWp)
- Domestic battery: up to 2,250 EUR
To benefit from these aids, the work must be carried out by an approved professional and meet technical criteria. Applications are made via guichet.public.lu or directly with Klima-Agence.
The Super-Reduced VAT at 3%
Another tax advantage for homeowners: the super-reduced VAT rate of 3% applies to renovation, extension, or fitting-out work in a dwelling occupied for more than two years. This notably concerns the construction of a veranda, provided it is attached to the main residence. Note: this VAT does not apply to the land or to architect fees if billed separately.
Administrative Steps: Permits and Regulations
In Luxembourg, any construction of a veranda over 10 m² requires a building permit. Applications are made at the commune. Allow a processing time of 2 to 4 months. Permit costs vary from 500 to 2,000 EUR depending on the commune. It is recommended to hire an architect to prepare the file and comply with the General Development Plan (PAG) and communal regulations.
Energy Standards and Data Protection
Verandas must meet energy performance standards (RGD Energie). For windows and doors, the Uw coefficient must be below 1.4 W/m²K. Regarding data protection, if you install sensors or cameras, you must comply with the rules of the CNPD (National Commission for Data Protection).
Tips to Optimize Your Budget
To reduce the total cost of your project, here are some suggestions:
- Choose a south or southwest orientation to maximize solar gains and reduce heating needs.
- Opt for reinforced insulation glazing (triple glazing recommended) to improve energy efficiency.
- Integrate photovoltaic panels on the veranda roof to benefit from subsidies and produce your own electricity.
- Compare several quotes from approved artisans to get the best value for money.
By planning carefully and taking advantage of available aids, you can achieve a veranda in Luxembourg at a controlled cost in 2026.
