Apartment Building as a Prefab House: Prices and Providers 2026
Anyone planning an apartment building as a prefab house first looks for prices – and quickly hits a peculiarity: such objects are calculated project-based, because the plot, the mix of dwellings and the fit-out shape the price. This guide calmly classifies the price question in 2026, names usual market ranges as orientation, presents the four providers listed in the database alphabetically and explains why all models run under "price on request". Added to this are serial building as a trend and general notes on the funding of new rental housing.
Short answer: A multi-family house (Mehrfamilienhaus) built as a prefab is almost always calculated on a project-specific basis, because the plot, the mix of flats and the fittings shape the price. All listed multi-family house models therefore run under "price on request". As a rough guide, market observers usually quote ranges in the mid six-figure area per residential unit for a turnkey new build, in each case excluding the plot. As of 2026.
What does a multi-family house as a prefab cost in 2026?
Unlike a classic single-family house, there are no reliable catalogue prices for a multi-family house. The reason lies in the nature of the object: a building with several residential units is tailored to a specific plot, a planned mix of flats and a marketing objective. In our database, all multi-family house models therefore carry the note "price on request" — the manufacturers calculate each project individually. We deliberately do not invent prices per model. A structured entry point covering all the routes is provided by the overview of the multi-family house.
Usual market ranges help with a first orientation. For the turnkey new build of a multi-family house, figures in the mid to upper six-figure range per residential unit are often quoted, depending on region, fittings and flat size; per square metre of living area these reference values roughly move within the range of several thousand euros. These ranges are not manufacturer prices but a general classification for a feasibility check. The bandwidth is wide, because plot costs, site development, an underground car park, a lift and the energy standard weigh heavily. Anyone wanting to gauge the order of magnitude of an investment will find the basics in the overview of home-building costs and in the cost calculator.
Reference ranges for building a multi-family house — usual market values, not manufacturer prices (as of 2026). Excluding plot and ancillary construction costs.
| Cost block | Reference range | Note |
|---|---|---|
| Shell/structure per m² | roughly €1,800–2,800 | timber prefab, no basement |
| Turnkey per m² | roughly €2,500–4,500 | depending on fittings and standard |
| Lift (system) | in the five- to six-figure range | usual from a medium number of storeys |
| Underground car park per space | in the high five-figure range | depending on the subsoil |
| Ancillary construction costs | roughly 15–20 % of building costs | planning, permit, fees |
Why 'price on request' is correct here
A multi-family house is an investment object. Its profitability is decided by the plot, the mix of flats, lettability and fittings — factors that must be established before planning. That is why the manufacturers in our database do not quote final model prices but calculate each object on a project-specific basis.
Which prefab providers build multi-family houses?
Four providers with multi-family house models are listed in our database. We list them alphabetically and expressly without ranking — this is not a ranking and not a test-winner comparison. All figures come from the stored provider profiles. A consolidated comparison is offered by the guide to the MFH prefab providers compared.
GROPYUS
According to its profile, GROPYUS stands for serial timber construction with the aim of climate-neutral neighbourhoods and delivers in Germany and Austria. The company is listed in the categories prefab house, multi-family house and single-family house and relies on a high degree of prefabrication. The average living area of the listed models is around 515 m² — an indication of a focus on larger residential buildings. Details in the GROPYUS provider profile.
Haas Fertigbau — multi-family houses
Haas Fertigbau, with the slogan "build better", operates throughout Germany, was founded in 1972 and offers multi-family houses both turnkey and as a shell house (Ausbauhaus). The provider offers by far the most multi-family house models in our database and covers a broad range from the compact three-family house to the townhouse with ten residential units. More in the Haas Fertigbau provider profile.
SchwörerHaus
SchwörerHaus from Baden-Württemberg (founded in 1950, slogan "This is my home.") manufactures using timber-panel construction and offers multi-family houses as a shell or turnkey variant. Its portfolio includes, among other things, a double pack of two cube houses and a three-storey trio with a gable roof. On request, the manufacturer takes on the basement production from a single source. Details in the SchwörerHaus provider profile.
WeberHaus
WeberHaus (founded in 1960, slogan "Living the future") operates throughout Germany and transfers its experience from ecological timber prefabrication to the multi-family house. The objects are planned individually, so that flat sizes and floor plan are geared to the desired mix of tenants or owners. More in the WeberHaus provider profile.

Anyone planning a single object in parallel will find the entry point at the single-family house.
Serial construction as a trend in multi-family house building
Multi-family house building in prefab construction benefits from the trend towards serial and modular building. Instead of planning every component individually, wall and ceiling elements — sometimes whole room modules — are prefabricated in the factory and assembled on site. This shortens the on-site construction time, makes processes more plannable and keeps quality consistent. For investors, repeatability counts above all: a proven flat type can be built several times, which lowers planning and construction risks.
Framework conditions and market figures on prefab construction are published by the German Prefab Construction Association (Bundesverband Deutscher Fertigbau, BDF). We do not derive specific object prices or quotes from this; the profitability of a multi-family house depends on the individual project. How serial construction and other developments play out in 2026 is put into context by our overview of the home-building trends 2026.
Funding for building new rental housing
For building new rental housing there are, in principle, funding programmes, including those of the KfW. The programmes and their terms change regularly, however — interest rates, loan amounts and requirements are not fixed permanently. We therefore deliberately do not quote specific programme numbers or interest rates. Only the current details on kfw.de and the advice of your financing bank are binding. Which programmes and requirements come into question for building new rental housing is put into context by the guide to MFH funding.
- Before planning begins, check which funding programmes for new rental housing are currently open.
- Set the energy standard early, because funding often ties in with it.
- Reconcile eligibility with the financing bank and the current KfW terms.
- Observe the order of applications: funding applications are often submitted before the project begins.
- Document the terms — they can change between enquiry and approval.
What drives the price of a multi-family house
Whether a multi-family house is economical is decided less by the pure price per square metre than by the interplay of many items. Besides the building shell, the plot and site development count, as does the number of storeys with the resulting requirements for fire protection and a lift, the number of parking spaces and the energy standard. The mix of flats also has an effect: many small units mean more bathrooms, kitchens and circulation space than a few large flats.
Price drivers for a multi-family house — qualitative classification (as of 2026). No specific prices per item.
| Factor | Effect on the price | Classification |
|---|---|---|
| Number of storeys | rising | fire protection, structure, lift from a medium height |
| Mix of flats | rising with many small flats | more bathrooms, kitchens, circulation |
| Lift/underground car park | strongly rising | technology and subsoil decisive |
| Energy standard | rising, but funding-relevant | higher building costs, possible funding |
| Degree of prefabrication | lowering with repetition | serial types reduce planning effort |
Note on transparency
Anyone wanting to follow the process from idea to letting will find the steps in the guide on building a multi-family house. Whether a prefab house is suitable as an investment is put into context by the article on the prefab house as a capital investment. How flats and circulation can be sensibly arranged is shown by the gallery of multi-family house floor plans.
