Quick answer
A solid-construction prefabricated house costs around €270,000 (100 m²) to €620,000 (160 m², KfW 40) turnkey in 2026, excluding the plot. It combines masonry or solid construction using brick, aerated concrete or precast concrete with the benefits of prefabrication. Walls are produced in the factory or assembled on site with extensive prefabrication, including a fixed price and a short four-to-seven-month build time. It costs 5 to 10 percent more than a timber prefabricated house but offers high thermal mass, acoustic insulation and resale value.
Solid prefabricated house: an overview
The Solid prefabricated house is one of Germany's most popular house types. Prefabrication brings out its strengths: a precisely predictable schedule, clearly defined costs and a high energy standard that readily meets the strict requirements for KfW support in 2026.
Industrial production in weather-protected factories enables wall and floor elements to be made with great precision. On site, the shell is generally erected and weatherproof within one to three days.
Advantages
- Very short, predictable build time
- High energy efficiency as standard in 2026
- Manufacturer's fixed-price guarantee
- Individual planning within a system-built home
Disadvantages
- Lower summer heat-storage capacity
- Internal acoustic insulation needs explicit attention
- Layout changes are difficult during construction
