Turnkey house: an overview

The Turnkey 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

How long does it take to build a prefabricated Turnkey house?

What is the least expensive turnkey prefabricated house in 2026?
The least expensive turnkey prefabricated houses start at around €230,000 to €270,000 for 120 to 140 m² in 2026.
