What B&O Group does

B&O Group (B&O Gruppe) is a German, owner-managed construction and building services group headquartered in Bad Aibling. The company operates two independent divisions: B&O Bau, which delivers energetic renovation, serial renovation, and new construction of multi-story residential buildings in wood and wood-hybrid methods (including roof extensions and parking deck overbuilding), and B&O Service, which provides technical maintenance, modernization, and insurance-damage repair for rental apartments. B&O targets German housing companies and cooperatives as its primary enterprise customer segment, serving them through 24 wholly-owned regional subsidiaries with in-house planning departments.

The group's technology foundation rests on vertical integration into serial construction: it produces timber wall elements and facades at its Frankfurt (Oder) plant (25,000 sqm capacity, opened 2022-2023) and prefabricated bathroom modules at its Prelog, Croatia facility (operational since 2018). Combined with approximately 1,000 in-house craftsmen and a network of nearly 1,000 partner craft businesses, this enables complete renovation of 4,000 apartments per year and construction of ~1,000 new wood/wood-hybrid apartments per year, with multi-story buildings delivered in under six months. B&O also operates the 70-hectare ForschungsQuartier in Bad Aibling as a real-world R&D laboratory, where the award-winning "Einfach Bauen" (Simple Building) research project with TU Munich and Transsolar was developed.

The business model is B2B construction services on a project/quote basis for new build and renovation, paired with recurring maintenance and damage-repair contracts through B&O Service. The company manages approximately 600,000 apartments for housing companies and handles about 1 million damage claims annually, with reported annual performance of ~350 million EUR. Headcount exceeds 1,000 across the German operations, and a generational leadership transition was completed in 2024, with Friederike Münn and Andreas Böhm succeeding Peter Münn and Ernst Böhm. The company is privately held, owner-managed, and has no external institutional investors identified in the source material.
