Prefab house costs and funding 2026 at a glance

After the sharp increases of recent years, the build costs for a prefab house have now settled at a calmer level – as shown by the construction and property price index published by the Federal Statistical Office (Bau- und Immobilienpreisindex). For 2026, budget on average for a turnkey house at €2,600 to €3,200 per square metre of bare living area, depending on region and chosen fittings standard. The latest figures on construction prices for residential buildings in February 2026 are provided by the most recent Destatis release.

Bear in mind: the stated house price often makes up only 60 to 70 percent of the total. Ancillary construction costs, earthworks, slab or cellar and outdoor works must be factored into your calculation – how easily mistakes creep in here is made clear by the consumer advice centre (Verbraucherzentrale) in its overview of typical cost and contract traps when building.
