What does a prefab house cost in Germany in 2026?
Advertised house prices are only one part of the final budget. Current German market overviews often place turnkey prefab homes around €2,500–€3,300 per square metre, but the exact scope of “turnkey” differs by provider.
For a useful comparison, separate the house, foundation or basement, plot, connections, professional fees, permits and landscaping. This prevents a low headline price from being mistaken for the full project cost.
The five major cost blocks
| Cost block | Check carefully |
|---|---|
| House | Finish level, specification, energy standard, design |
| Foundation | Slab or basement, excavation, soil report |
| Plot | Purchase, tax, notary, servicing |
| Ancillary costs | Planning, permits, surveying, insurance, connections |
| External works | Driveway, drainage, terrace, garden, carport |
The PFlower calculator keeps these blocks separate so you can compare scenarios on the same basis.
Example for 120 m²
For 120 m² of living space, the house-only figure can easily move from roughly €300,000 toward €400,000 depending on finish and specification. The total project budget will be higher once site-specific items are included.
Why price per m² is not enough
Smaller homes can have a higher price per square metre because the kitchen, bathroom and building services are concentrated into less space. Larger homes may gain some efficiency, but complex roofs, extensive glazing and non-standard layouts can cancel it out.
How to compare quotations
- Compare the same finish level.
- Read the detailed scope of works.
- Separate groundworks, slab and utility connections.
- Record upgrade allowances and likely extras.
- Keep a contingency for site-specific surprises.
Which decisions push the budget up?
Floor area is only one driver. Complex roofs, large spans, extensive glazing, extra bathrooms and premium building services can affect materials, engineering and installation. Even a small design change can touch several trades. Create three lists—essential, desirable and easy to add later—so specification choices do not consume the contingency needed for site-specific surprises.
Turn a quotation into a project budget
Ask for a transparent cost structure rather than one headline number. Mark every item as included, optional, by-owner or unresolved. Groundworks, crane access, utility connections, drainage, surveying and external works deserve their own lines. If two suppliers use different definitions of turnkey, a standard comparison sheet is the only fair way to compare them.
Protect the contingency
A contingency is not an upgrade allowance. It exists for uncertain ground conditions, utility routes, design changes required during approvals and other genuine unknowns. Keep lifestyle upgrades such as premium finishes in a separate budget so the project reserve remains available until the build is substantially complete.
When the cheaper house is actually cheaper
A lower house price can be excellent value when the scope matches your project and major later extras are unlikely. It is not cheaper if excluded work has to be purchased separately. Compare each option to a similar habitable end state; the goal is not the lowest entry price but the smallest gap between planned and final project cost.

Frequently asked questions
What is a realistic 2026 price per m²?
German market guides often show roughly €2,500–€3,300/m² for turnkey prefab houses, with substantial variation.
Is the plot included?
Usually not. Land and site-specific costs should be budgeted separately.
Should I keep a contingency?
Yes. Ground conditions, utility work and specification changes can move the final cost.
