Tiny house in Luxembourg: the 20 most common questions.
Twenty tiny house questions per country — permits, delivery, customs, connections, winter use, cost and letting. The answers are project orientation and do not replace a ruling from the responsible authority.
As a rule, yes. Once a unit stands permanently in one place and is used for occupation, Luxembourg treats it in planning law as a structure. the commune is responsible. Whether a procedure applies, and which one, is decided at the specific plot — not by the product.
the commune. MODUNERA supplies the building and the technical documentation; the decision on admissibility, procedure and conditions rests entirely with that body. Get the answer in writing before you order.
the plan d'aménagement général (PAG) and the associated plan d'aménagement particulier (PAP) governs. It sets the permissible type of use, the way of building, the buildable area and the servicing. A plot with the wrong designation for your project cannot be rescued by any technical solution.
Permanent living is possible where the PAG zone permits residential use and the autorisation de construire is granted. Because municipalities are small, practice differs noticeably from place to place.
Campsites and leisure locations carry their own conditions and usually limits on length of stay. Clarify operator rules and municipal requirements together.
What counts is permanent placement, not the chassis. A unit that stays is treated as a building project and needs the autorisation de construire.
As project orientation we work with roughly 7,000 € ex works to the agreed point in Luxembourg. The figure is an average; the route is confirmed per project. The final amount depends on route, access, crane requirement and date; a freight commitment only exists with the checked quotation.
The unit travels whole on a low-loader. The route runs overland. Because the topography is lively, the final approach to the plot is more often the bottleneck than the long haul. The exact date is fixed together with the unloading point, because in practice the last hundred metres cause more trouble than the route.
Türkiye and the EU are linked by the customs union. With an A.TR certificate, industrial goods generally attract no duty; Luxembourg import VAT remains.
Luxembourg VAT at 17 per cent applies — the lowest of the five destinations. As of 2026-08-14. The rules in force at the time of delivery govern; the tax treatment of your specific case is for your tax adviser to confirm.
Pad, strip or screw foundation, depending on soil, frost depth and what the permit requires. Sloping sites are common in Luxembourg; standing area, access and crane position have to be planned together. The work is carried out locally; we supply the load assumptions and bearing points.
Up to the plot boundary by the local utilities, from there by local trades. Cost is driven almost entirely by the distance to the existing network. The commune sets the connection conditions; distances are usually short but the procedures are formalised.
Site-dependent. Where residential use is approved a regular connection is generally expected; the commune decides case by case.
Yes — the climate is temperate, and specification follows the slope and wind exposure more than extreme temperatures. Insulation thickness, glazed area, ventilation and heating system are decided together before production, not retrofitted.
By heating season, snow load zone and wind zone at the actual address. The build-up broadly matches western Germany; the decisive factor is the actual altitude of the site. A build-up that is enough for a summer unit is too thin for permanent living at the same address.
Ex-works base plus delivery gives the first number; foundation, connections, unloading, local planning, permit fees and insurance come on top. Count these from the start, or the budget moves after the order is placed.
MD 3 and MD 5 are planned most often in Luxembourg, because many projects need an extra room for a home office and plots are limited.
Short-term letting is regulated municipally and notifiable in some communes. Settle that before the investment decision, not after.
Transport cover for the delivery, building or natural-hazard cover for operation, and operator liability if you let it. Settle cover before delivery — afterwards your negotiating position is worse.
Five things: a written answer from the commune on admissibility; access and unloading point with photographs and dimensions; servicing and the distance to the network; the type of use with the number of people; and the budget range including the secondary items. With those five, an enquiry becomes a plannable project.
