Prefabricated house prices 2026: Prices per square meter by house type and level of expansion

A turnkey prefabricated house with 140 square meters of living space will cost between 360,000 and 460,000 euros in 2026 - excluding land, additional construction costs and outdoor facilities. The exact amount depends on the energy standard, the region and the equipment. Per square meter, turnkey houses cost 2,600 to 3,300 euros, and ready-to-build houses cost 2,100 to 2,600 euros.

The turnkey prefabricated house price per square meter in 2026 will be between 2,500 and 3,300 euros. Converted houses start at 1,900 to 2,600 euros per square meter, kit houses at around 1,500 euros. In the premium segment with upscale amenities, KfW 40 standard and individual architecture, 3,300 to 3,850 euros per square meter are realistic. Important: These values ​​apply to the house from the top edge of the floor slab - the property, floor slab/basement and additional construction costs (15 to 20 percent) are added.

A prefabricated house with 120 square meters of living space will cost between 300,000 and 400,000 euros turnkey in 2026 - depending on the provider segment, energy standard and equipment. As an extension house with your own contribution, 225,000 to 320,000 euros are realistic. 120 square meters is the most popular format for families with one to two children: typically four rooms on one and a half to two floors. Land and additional construction costs are added.

A prefabricated house with 130 square meters will cost between 325,000 and 430,000 euros in 2026. The surcharge compared to 120 square meters is around 25,000 to 30,000 euros - additional living space is comparatively cheap in a prefabricated house because technology, kitchen and bathrooms are already included as fixed costs. 130 square meters allow four to five rooms plus a study and are a good compromise between space and budget.

In 2026, a standard-sized turnkey prefabricated house will not be realistic for 200,000 euros - the cheapest providers start at around 230,000 euros for 120 square meters. The following are possible for 200,000 euros: an extension house with a high level of personal investment (from 190,000 euros for 100 square meters), a small house or bungalow under 90 square meters or a kit house. Attention: Land, floor slab and additional construction costs are not included in any of these prices - the total investment is correspondingly higher.

The additional construction costs typically amount to 15 to 20 percent of the pure house price. For a 400,000 euro house, that's 60,000 to 80,000 euros for earthworks, floor slab or basement, connections, notary, property transfer tax, surveying, building permit and construction management. Anyone who underestimates the item will quickly run into liquidity bottlenecks.

The range is enormous: in Munich and Stuttgart locations, prices range from 1,500 to 3,000 euros per square meter; in rural regions of Mecklenburg-Western Pomerania or Saxony-Anhalt, prices start at 60 euros per square meter. Nationwide, the median is around 280 euros per square meter of building land (as of 2026). In addition, there are development costs of 12,000 to 35,000 euros.

In 2026, a full basement will cost between 35,000 and 65,000 euros more than a floor slab. It is worthwhile if the property is expensive (additional usable space instead of expensive additional square meters of building land), if the hillside location suggests a cellar anyway, or if hobby rooms and technology require additional parking space. On cheap properties in a flat location, the base plate is usually more economical.

In 2026, banks will generally finance a maximum of 100 percent of the house price, but rarely the additional construction costs. At least 20 percent of the total costs are recommended as equity, i.e. around 100,000 euros for a 500,000 euro project. Those who start with less pay significantly higher interest premiums or have to resort to KfW programs such as home ownership promotion for families.

Three programs are particularly relevant in 2026: Climate-friendly new buildings (KFN) with low-interest loans of up to 150,000 euros per residential unit for Efficiency House 40 with the QNG seal; Home ownership support for families (WEF) with up to 270,000 euros for families with children and a household income of less than 90,000 euros; as well as BAFA heating funding with subsidies of up to 40 percent for heat pumps. Applications must be submitted before the contract is signed.

In addition to the pure house price, the following items will typically be incurred in 2026: land (regionally 50 to 3,000 euros per square meter), development 12,000 to 35,000 euros, soil report 800 to 2,500 euros, floor slab 25,000 to 45,000 euros or full basement 60,000 to 110,000 euros, house connections for electricity, Water, sewage, gas and telecommunications 8,000 to 15,000 euros, building permit and survey 3,000 to 8,000 euros, notary and real estate transfer tax 5 to 9 percent of the property price, outdoor facilities with access, terrace and fencing 15,000 to 40,000 euros as well as additional financing costs. In total, depending on the region, this is 80,000 to 180,000 euros above the house price.

Searches for “prefabricated house with price” target specific house models with stated guide prices instead of general price ranges. 35 providers are recorded in a detailed comparison on Fertig-haus.net, around three quarters of which publish entry-level prices per model, living space class and expansion level - for the rest, the price is determined by the provider only after individual needs have been clarified. Important: All provider guide prices are a fixed price for the provider's construction and service description, excluding land and excluding additional construction costs. Special requests, sampling upgrades and regionally different connection costs are added separately.

The final price of a prefabricated house is determined by around ten factors: living space and design (more compact is cheaper per square meter), construction method (wooden frame, wooden panel or solid concrete), expansion level (kit, extension or turnkey), roof shape (saddle cheaper than hipped or pent roof with dormers), energy standard (GEG minimum standard, KfW-40, KFN with QNG), building technology (heat pump, ventilation, PV system), Sampling (bathrooms, floors, doors), transport and assembly costs to the construction site, regional wage costs for the sub-trades as well as special project-specific requests. A serious calculation shows these positions individually in the construction and service description.

A turnkey prefabricated house up to 150,000 euros is only realistic in 2026 within very narrow limits: compact living space of a maximum of 70 to 90 square meters, simple rectangular floor plans, standard equipment without special requests and no basement. Even then, the 150,000 euros typically only cover the pure house price. The property, floor slab, house connections, outdoor facilities and additional construction costs add another 80,000 to 150,000 euros. If you are looking for a complete project for 150,000 euros, you should instead look at tiny houses, single houses under 60 square meters or kit houses with a high proportion of your own work.

The cheapest turnkey prefabricated houses in 2026 start at around 145,000 euros for around 80 square meters of living space, which corresponds to a price per square meter of around 1,800 euros. In a standard size (120 to 140 square meters), the cheapest offers start at around 230,000 to 270,000 euros. Providers such as Town & Country, Massa Haus and Allkauf are positioning themselves in this entry-level segment. Important to check: What exactly is included in the fixed price? Floor coverings, interior doors, sanitary objects above the standard class, painting and tiling work or outdoor facilities are often missing. The cheapest list price is rarely the economically best offer - the decisive factors are the scope of services, energy standard, construction quality and follow-up costs over the next 30 years.

Compare offers only on the basis of identical construction and service descriptions - item by item. Pay particular attention to: included expansion level, energy standard (GEG vs. KfW-40 vs. KFN-QNG), heating technology, floor coverings, sanitary class, interior doors, entrance door, staircase design, plaster or wallpaper, completion details such as painting and tiling work, sampling budget for special requests, fixed price in months, assumption of additional building costs, outdoor facilities, and payment plan according to MaBV. An independent expert from the VPB or BSB checks the contract for 1,500 to 3,500 euros before signing - experience has shown that this investment avoids additional costs of 20,000 to 60,000 euros.

A turnkey prefabricated house will cost between 2,600 and 3,300 euros per square meter of living space in 2026. For a 140 square meter single-family home, this results in a pure house price of 360,000 to 460,000 euros. Premium providers with a high level of prefabrication and the KfW 40 NH standard achieve 3,500 to 4,200 euros per square meter. Important: "Turnkey" is not a legally protected term - the specific scope of services must be listed item by item in the construction and service description. Typically not included are the property, floor slab or basement, outdoor facilities, kitchen and some floor coverings in adjoining rooms.

For most German prefabricated house providers, turnkey means that the house is handed over ready for occupancy - i.e. the outer shell is sealed, the interior is complete, plumbing and electrics are installed, floor coverings are laid, painting and tiling work is carried out. However, the term is not legally defined and varies from provider to provider. Before signing the contract, you should check whether floor coverings are included in all rooms, interior doors of the desired class, sanitary objects above the minimum class, wallpaper or wall paint, stairs in the desired version, outdoor facilities, carport and kitchen. What is missing often costs twice the market price as a special request.
