Turnkey House Construction in Luxembourg

From the land to the keys — one contact, one quote.

Building a turnkey house in Luxembourg is, in theory, a once-in-a-lifetime project. In practice, it means coordinating dozens of trades, comparing dozens of quotes, making dozens of decisions. Most families spend a year and a half chasing contractors.

Real Constructions’ turnkey house formula spares you all of that. You entrust us with your house construction project in Luxembourg — we handle everything. One quote, one schedule, one contact (Paulo or Alberto Lucas). You arrive at the handover without ever having to manage day-to-day site work.

Building your house in Luxembourg: two options

1. Your plans — with your architect

You already have your architect and your plans. We take over the full execution: from structural works to interior finishes. We work in close coordination with your architect, who oversees compliance with the plans.

2. Our plans — project designed together

You have a piece of land and an idea — we put our partner architects and our experience at your service to design and build your turnkey house in Luxembourg from A to Z. One team, one validation cycle, one global quote.

House construction in Luxembourg meeting current energy standards

We build according to your needs and energy budget:

  • Energy class B — current Luxembourg standard, high-performing
  • Class A — low energy, optimized
  • Class AA / AAA (passive or near-passive) — very low energy use, the house heats itself almost on its own

We give honest advice on return on investment: passive housing is not always the right fit depending on your profile and planned ownership duration.

Our complete service

  • Land search (optional) — if you have not yet found your plot, we help you with our network in Luxembourg
  • Administrative support — building permits, municipal procedures, energy aid applications (myenergy, premiums), introductions to banks and notaries
  • Architectural design (option 2) — with our partner architect

  • Guided choice of finishes — showroom visits, partner suppliers, design advice

Frequently Asked Questions — house construction in Luxembourg

How much does a turnkey house cost in Luxembourg?

The cost of a turnkey house depends on many factors: living area, level of finishes, target energy class (B, A, AA or AAA), architectural complexity, and site constraints. To give you a number that means something, we first need to define your project precisely together. The detailed quote is free, firm, and global — one price for the whole house.

How long does building a house take in Luxembourg?

8 to 14 months between construction start and handover, depending on complexity. Add 3 to 6 more months for design, permits, and administrative procedures.

Can you help us find land in Luxembourg?

Yes, this is an option of our turnkey formula. We have a network of notaries, agencies, and municipalities that flag available plots to us.

Do you work with any architect?

Yes. If you already have an architect, we adapt. If not, we propose trusted partners we work with regularly.

What guarantees do you offer on the house?

Completion guarantee (1 year), two-year warranty on equipment items, and Luxembourg ten-year warranty on structural elements. All our insurances are based in Luxembourg, compliant with local law.

What if I want to change something during construction?

As long as it is technically possible and you accept it via written addendum, we adapt. We tell you the additional cost and any schedule impact before making the change.
