Bavarian Ministry of Building issues first type approval
Significantly faster approval processes for construction projects
B&O Bau GmbH from Bad Aibling with its first type of residential building
The Bavarian Ministry of Building issued the first type approval for a residential building in October 2025. Building Minister Bernreiter: We want to push the envelope when it comes to housing construction: Type approval enables much faster procedures for buildings that are to be built several times with the same or similar construction. This makes serial planning and construction even more attractive. Particularly with a high level of prefabrication, such as in timber construction, the system can show off its strengths and bring real added value.
The type approval is anchored in the Bavarian Building Code. If structural systems are to be built several times in the same design or in different designs but according to a specific system of components, a type approval can determine that requirements, for example with regard to fire protection, have been met.
The advantage of a type approval is that these requirements are not checked again every time this structure is implemented. Instead, during the specific building permit process, only the location-dependent aspects need to be examined, such as the distances to the property boundaries or the performance of the local fire department. Type approvals therefore help to make construction quicker and easier.
The Bavarian State Ministry for Housing, Construction and Transport issues type approvals upon application. B&O Bau from Bad Aibling has now received the first type approval. The subject of the application is a house whose external walls are constructed with mass-produced solid wood wall elements. The house can have with or without a basement, with or without balconies and between four and eight upper floors.
Tallest rental residential building with load-bearing solid wood walls in Furth
In Furth, B&O Bau has already implemented a pilot project modeled on type approval. With 24 affordable apartments, the eight-story building owned by the Housing Association of the City of Furth (WBG) offers barrier-free and therefore age-appropriate living space for people with low and middle incomes. Within 13 months, new living space was created through sensible densification of the existing building. The wooden wall elements and prefabricated bathrooms were precisely prefabricated by B&O Bau and installed directly on site. The Free State of Bavaria supported the project with around 4.6 million euros as part of the social rental housing subsidy.
