In brief
A modern gable-roof house (Satteldachhaus) costs, as a prefab, turnkey around €300,000 (120 m²) to €630,000 (180 m², premium) in 2026, excluding plot and ancillary construction costs. Per square metre, the price is, as a guide value, between €2,500/m² and €3,700/m². Characteristics are a clear, often asymmetrical form, a plain gable roof with no or only a slight roof overhang, floor-to-ceiling windows and a reduced render or timber façade – the traditional classic in a contemporary form. In terms of price, it sits between the classic gable-roof house and the flat-roof or Bauhaus-style house: the decisive factor is the comparison with the traditional gable-roof house (from about €2,300/m²) on the one hand and with the flat-roof house with more elaborate sealing (from about €2,400/m²) on the other. Typical living areas range between 120 and 180 m². Floor-to-ceiling glass surfaces, a second full storey instead of a knee wall and a knee-wall omission drive the price; the simple gable roof, by contrast, remains cheaper and more robust than a flat roof.
What a Modern gable-roof house as a prefab home costs – the overview
With the Modern gable-roof house as a prefab home, prefab construction pays off above all in the price: a binding fixed price ex works protects against nasty surprises, the short build time lowers the interim financing costs and the high energy standard gives you access to KfW funding in 2026. It is precisely these three levers that keep the calculation predictable.
The wall and ceiling elements are built to the millimetre in weather-protected factory halls, and the shell often stands on the building site after just one to three days. Less time on the building site means less weather risk – and that also lowers the price in the end.
This speaks in favour on price
- Binding fixed price – calculable from the start
- Short build time reduces the interim financing
- High energy standard secures KfW funding
- Price can be adjusted deliberately via the finishing stage
This drives the price up
- An upmarket selection of finishes can raise the per-m² price considerably
- The plot and incidental building costs always come on top
- Subsequent floor-plan changes cost a lot
Putting per-square-metre costs and the total price 2026 in context
The price for a Modern gable-roof house as a prefab home depends decisively on the finishing stage: turnkey, the per-square-metre costs in 2026 are around 2,000 to 3,500 EUR/m², as a shell house from about 1,300 EUR/m². From €300,000 is a realistic starting price for the turnkey basic version.
In addition to the pure house price, factor in the incidental building costs (around 15–20 % of the construction sum), earthworks and a buffer. With our cost calculator you can determine your individual total price. How each price factor works is shown on the Prefab house prices 2026 page.
For a modern gable-roof house as a prefab, reckon on turnkey costs of €300,000 to €630,000 in 2026 – depending on living area, fit-out stage and provider segment. As a guide value, the price per square metre ranges between about €2,500 and €3,700. The following table shows which price ranges are realistic by living area and price segment:
| Living area | Entry segment | Mid segment | Premium segment |
|---|---|---|---|
| 120 m² | €300,000 – 355,000 | €355,000 – 410,000 | €410,000 – 465,000 |
| 140 m² | €350,000 – 415,000 | €415,000 – 480,000 | €480,000 – 540,000 |
| 160 m² | €400,000 – 470,000 | €470,000 – 545,000 | €545,000 – 595,000 |
| 180 m² | €445,000 – 520,000 | €520,000 – 585,000 | €585,000 – 630,000 |
Non-binding guide values for 2026, turnkey, excluding plot and ancillary construction costs (15 to 20 percent). Large floor-to-ceiling window surfaces, a second full storey instead of a knee wall and an upmarket interior fit-out raise the price. Compared with a classic gable-roof house with a roof overhang and standard windows, the modern design lies about 5 to 10 percent higher; compared with a flat-roof or Bauhaus-style house, it usually stays cheaper thanks to the robust, unelaborate gable roof. Check in advance whether the development plan permits the roof pitch and roof overhang for the modern interpretation.
