Permits, mortgage and insurance for a timber house in the Netherlands

You need an environmental permit (omgevingsvergunning) from your municipality, just as for any new-build home. The process is identical to masonry. What helps: our homes meet all Dutch building standards, and the permitting authority receives properly substantiated calculations from your structural engineer.

Since 1 January 2024 the Dutch Quality Assurance Act (Wkb) also applies: an independent quality assurer checks during construction that your home meets the Building Decree. Our experience: quality assurers are generally positive about prefab timber — factory production is far easier to inspect than a building site, our CNC tolerance of ±1 mm means predictable quality, and the CE marking and blower-door tests are already external quality checks.

ZTC holds CE marking under ETA-21/0014: the European counterpart of the Dutch KOMO mark, recognised as equivalent by the Building Decree. We currently do not hold a KOMO certificate itself — for private projects it is usually not needed. If questions arise, we help demonstrate that ETA-21/0014 suffices.

Good to know: Dutch government policy actively steers towards bio-based construction. In several places, subsidies and accelerated permitting for bio-based projects have been introduced — ask your municipality about regional schemes.

All Dutch mortgage lenders finance prefab timber homes, provided the home meets the Building Decree, a building permit is in place and the home can be valued. For the valuation it helps to mention that the home is CE-marked and falls under Eurocode 5.

The interest rate is usually the same — and sometimes better: a ZTC home almost certainly achieves energy label A++ or better and thereby qualifies for a green mortgage discount. Ask your adviser. The valuation of a well-built timber home is almost always equal to or higher than comparable masonry, mainly thanks to the energy label and lower heating costs.

Most Dutch building insurers cover timber homes on the same terms as masonry — sometimes slightly better. Our advice: request quotes from two or three insurers, and mention that it concerns a prefab timber home with CE marking ETA-21/0014. We supply the accompanying documentation.

Standard: 10 years on the structure, 5 years on production defects and 2 years of general product warranty — optionally extendable to 15 or 20 years. Your dedicated Dutch point of contact handles any warranty matters directly with the factory.
