What does a detached house cost as a prefabricated house in 2026?
Short answer: Turnkey detached houses start in 2026 at around €2,100 per square metre. The detached houses in our portal with a stated starting price roughly range between about €135,000 and €698,000, depending on living area and fit-out. The plot, servicing and ancillary construction costs are added in each case. All figures are ranges, as of 2026, depending on fit-out and region — not a ranking.
A detached house is a free-standing residential house for one family or household. As a prefabricated house, it is prefabricated in the factory and assembled in a short construction time. The price is determined above all by living area, completion stage, energy standard and plot. The house-building costs page offers a full cost overview; a first budget estimate is provided by the Cost Calculator.
Detached house fully planned
Would you like to understand the features, advantages and limits of the house type in depth? The house-type page describes the detached house as a building form with fully planned concepts, while this hub bundles all the surrounding topics. Both complement each other.
Detached house fully plannedWhy a detached house?
The detached house offers the greatest freedom in floor plan, garden and design. It stands free on the plot, has no shared walls with neighbours and can be tailored individually to your own life situation. As a prefabricated house, it combines a short construction time with an early, predictable price.
- Free-standing, plenty of design freedom
- Factory-prefabricated, short construction time
- Early fixed price and high energy standard
- Flexible: extendable up to a granny flat
If you prefer single-storey living, you will find the alternative under Bungalow.

Prefabricated or solid: planning a detached house properly
Both construction methods lead to a high-quality detached house. A prefabricated house is prefabricated in the factory, is usually ready to move into more quickly and offers a fixed price early on. A solid house scores with its thermal mass and is regarded by many as particularly value-stable. Costs and energy standard can be achieved similarly in both cases; there is no blanket ranking.
More important than the construction method is a well-thought-out floor plan. Plan rooms according to actual use, think about the home office, storage and short routes, and keep a later extension open. Ideas for this are provided by the floor plans for a detached house. If you want to accommodate two households, you will find options with the two-family house.
