A timber prefab home is insured like any house once it stands on your land, but the start date matters. BioBuilds delivers DAP with all-risks cargo insurance, so the transport risk is covered until the home is available at your destination. From unloading onward, your own cover must be in place. Insurers ask about the construction, the cladding, the roof and the location; giving them the exact specification gets you a quote that will hold.

Insurers are familiar with timber houses, and a factory-built home on a permanent foundation is a building like any other. What buyers often miss is the handover moment: the house arrives finished, so it needs cover from the day it is lifted onto the foundation, not from the day you move in. This guide explains when your cover must start, how insurers look at timber construction, what a building policy covers, and how warranty and insurance divide the work.

When does your insurance need to start?

BioBuilds delivers on DAP terms (Delivered at Place, Incoterms 2020), with all-risks cargo insurance during transport. The transport risk stays with BioBuilds until the home is available at the agreed destination, ready for unloading. That is also when it is inspected on the trailer and the final payment falls due.

From then on, the house is yours to insure:

Cover to arrange before delivery
  • Construction or installation insurance from delivery, with written confirmation that unloading, crane lifting and assembly are covered.
  • Confirmation that the crane company carries liability insurance for the lift.
  • Cover for any remaining site or interior works, followed by building insurance from completion.
  • Third-party liability for the building site, where your country or lender expects it.

Ask your insurer early, because many policies for houses under construction differ from policies for finished homes. A prefab house is usually closed and weatherproof on the day it arrives, which shortens the construction phase.

Do timber homes cost more to insure?

It depends on the insurer and the country. Insurers rate buildings by their construction, roof covering, location and natural-hazard exposure. Some treat modern timber-frame homes like masonry; others classify them separately, often by whether the walls and cladding are fire-retardant. A home with timber cladding may be classified differently from one with a rendered or mineral facade.

The best way to avoid surprises is to request quotes before you sign, using the exact specification of the house you are buying, and to compare several insurers.

Key Takeaway

Give insurers the real specification, not "prefab". Wall build-up, cladding, roof covering and heating system decide the classification, and a quote based on the right facts is one that holds when you claim.

What should you tell the insurer?

  • Construction: timber-frame walls with wood-fiber insulation, the wall build-up and any fire-resistance documents your country requires.
  • Cladding: BioBuilds offers Yakisugi or Lunawood thermowood cladding; name the one you chose.
  • Roof: a low-slope roof with an EPDM membrane.
  • Foundation: ground screws or another foundation, with the engineer's design.
  • Heating: the all-electric heat pump specified for your BioBuilds Turnkey home, or the heating system chosen for Exterior Finished or later interior work. Declare any combustion appliance.
  • Location: flood, storm and other natural-hazard exposure, which the insurer checks itself.
  • Value: the rebuild value, including the house, foundation and connections, not the plot.

What does building insurance cover?

A building policy typically covers fire, lightning and explosion, storm and hail, and escaping water, with natural hazards such as flood, heavy rain or earthquake often as an add-on. Some countries add compulsory cover: Romania, for example, requires a basic policy against earthquake, flood and landslide for every home. Check what your lender requires before signing the mortgage.

Insurance or warranty: what covers what?

Insurance pays for sudden damage from outside events: a fire, a storm, a burst pipe. A warranty covers defects in what you bought. BioBuilds gives a 5-year structural guarantee in addition to your statutory rights for defects, and the makers of components such as windows, the heat pump and the ventilation unit give their own warranties. Keep the documents together; you will need both kinds of cover over the life of the house.

To see the price of your home before you request insurance quotes, configure it. Prices start from €78,000 for Wanderlust 48 in Exterior Finished, including an illustrative 19% German VAT.
