AUCTUS invests in Rossmanith GmbH & Co. KG as a new platform for an integrated facade construction group


The transaction

AUCTUS is pleased to announce the closing of a strategic partnership with Rossmanith GmbH & Co. KG (“Rossmanith”). Rossmanith, headquartered in Heidelberg, was founded in 1947 and has established itself in the region and beyond as a reliable, integrated facade constructor for the entire building envelope. Its customers are primarily larger industrial companies as well as public institutions. Rossmanith becomes the platform company of a new facade construction group that combines the highest architectural standards and emission-reducing measures in an integrated manner.


Rossmanith is known on the market for the development and construction of sophisticated window and facade constructions in wood-aluminum combinations, an aesthetically pleasing, sustainable and trendy combination of materials. The facades are produced in a newly built, highly functional production hall in Heidelberg, where the company also trains its future junior staff. Several trainees have already been honored with awards from the German „Handwerkskammer” at regional and state level. Rossmanith’s strong focus on quality is also reflected in its involvement in numerous award-winning projects, such as the construction of a prefabricated mullion-transom facade made of wood-aluminum at the DAV federal office (winner of the German Timber Construction Award 2023):

AUCTUS strategy

The German facade construction and building market is characterized by many small and medium-sized, often family-run companies, many of which have a long-standing industry network, high-quality niche focuses and excellently trained specialists. “Sustainable facade construction will play a decisive role in the energy revolution, in which buildings are at the center of attention due to their high (direct and indirect) emissions,” says Marvin Aurnhammer from AUCTUS, explaining the investment decision.  With Rossmanith as its initial investment, AUCTUS plans to build an integrated group of high-performance facade manufacturers with a high level of material and planning expertise that can meet these requirements and offer its customers the highest quality. “Germany has first-class expertise in the field of innovative facade systems enabling us to tackle an increasing complexity in the segment,” adds Florian Aichinger, who will play a key role in supporting the international expansion strategy.


Buy-and-Build – What we are looking for

The Group’s regional focus is on the DACH region as well as neighboring European regions, particularly Italy and Eastern Europe. Relevant target companies construct entire building envelops and facade systems (mullion-transom facades and element facades) with their own production capacities and focus on quality, reliability, sustainability and innovation. Ideally, the target companies generate an EBITDA > EUR 2 million.

The group’s development is supported by industry experts Dr. Oliver Behnen ( / +41 78 229 96 33) and Prof. Dr. Frank Wellershoff ( / +49 152 336 154 58).
