Building an apartment building 2026: prefabrication, prices, providers
The new build of an apartment building sits in 2026 within a rough market range of around €2,400 to €3,800 per square metre of living space, in each case plus additional construction costs, plot and site development. At 75 square metres per residential unit, as a guide this corresponds to around €180,000 to €285,000 per unit. Serial prefabrication shortens the build time through prefabrication – according to industry figures from the German Prefabricated Building Association by up to 30 to 50 percent compared with conventional execution.

What does an apartment building cost in 2026?
The new build of an apartment building sits in 2026 within a rough market range of around €2,400 to €3,800 per square metre of living space, in each case plus additional construction costs, plot and site development. At 75 square metres per residential unit, this gives a guide of around €180,000 to €285,000 per unit. The actual costs depend on apartment mix, fittings, region and efficiency standard. Sources such as the Federal Statistical Office and KfW provide the basis. As of 2026.
What is serial construction?
Serial construction refers to the erection of residential buildings from prefabricated, recurring components or room modules. Walls, ceilings and sometimes complete apartments are produced weather-independently in the factory and assembled on site. Standardisation reduces planning effort and sources of error and, according to industry figures from the German Prefabricated Building Association, shortens the build time. The approach is particularly suited to apartment buildings with similar apartments. As of 2026.

Planning an apartment building in prefabrication
A prefabricated apartment building combines prefabricated components with project-specific planning. The usual range spans from the 3-family house to the 8-family house; serial concepts and neighbourhoods go beyond that. Economic viability is decided early: through the apartment mix, space efficiency and site development. Initial pointers are provided by the apartment building floor plans and the overview of the apartment building as a prefabricated house.
The cost side can be roughly narrowed down with market ranges, but a reliable price only results from a specific offer. Details are bundled by the guide on apartment building prices, and the process is described by the guide building an apartment building. For an initial budget estimate, the cost calculator is suitable, and the suitability of a plot is checked by the plot check.
On the topic of funding, in 2026 in outline the KfW funding for climate-friendly new build as well as tax instruments such as declining-balance depreciation and the special depreciation under Section 7b of the Income Tax Act come into consideration. Specific interest rates, programme numbers and deadlines change regularly. Binding information is provided by tax advice and KfW. As of 2026.
