Nothing about a tiny house project is decided by the house. The plot decides — its designation, its servicing and the use you intend. This is the subject that ends most projects before they start, and the one that costs nothing to check first.
The plot decides, not the product
A tiny house is not a legal category. In all five of our destination markets the question is the same: is a structure permissible on this plot, for this use, at this size? Germany asks it through the Bebauungsplan or §34/§35 BauGB, the Netherlands through the omgevingsplan, Denmark through the lokalplan and zone status, Luxembourg through the PAG and PAP, Switzerland through the zoning ordinance. A manufacturer cannot answer any of them. What a manufacturer can do is supply the structural data, the dimensions, the build-up and the technical documentation the application needs — and that is what we supply.
Wheels do not change the answer
The most persistent misunderstanding in the European tiny house market is that a chassis converts a building into a vehicle. It does not. Every one of the five markets looks at how the unit is actually used: if it stands in one place and people live or sleep in it, planning law treats it as a structure, registration plates or not. The chassis matters for transport, for the option to relocate later, and sometimes for the procedure — it does not create an exemption from planning law.
What to ask, and how to ask it
Write to the authority, not to a forum. Describe the plot by its address and parcel number, state the intended use in plain words (permanent residence, holiday use, letting, home office), give the external dimensions and the intended foundation, and ask two questions: is this admissible, and which procedure applies. Ask for the answer in writing. A verbal 'that should be fine' from a counter has no value when a neighbour objects eighteen months later.
Insurance follows the permit, not the other way round
Transport cover applies during delivery. Building or natural-hazard cover applies once the unit stands. If you let the house, operator liability applies on top. Insurers ask what the planning status is — a unit standing without the permit it needed is difficult to insure and difficult to sell. Settling the permit question first is therefore not bureaucratic caution; it is what makes the rest of the project insurable.
