BAUM Group

What BAUM Group does

BAUM Unternehmensgruppe is a family-owned real estate company headquartered in Hannover, Germany, founded in the early 1990s and operating for over three decades. Its core activities are real estate development, ownership, and management, anchored by an owned portfolio of approximately 185,000m² of residential and commercial space across Hannover, Garbsen, Langenhagen, Bemerode, Braunschweig, and Goslar, plus a 31,600m² office ensemble (Riethorst-Ensemble) acquired in January 2026 that was fully leased within months. The group serves residential tenants through a ~2,600+ unit portfolio and serves commercial tenants ranging from SMEs to enterprise and public-sector institutions, including NBank and GTU Unternehmensgruppe as recent anchor tenants.

Beyond real estate, BAUM operates three adjacent businesses through wholly-owned subsidiaries: BAUM Hotelbetriebe runs two Marriott-franchised Courtyard hotels (Hannover Maschsee with 149 rooms and Wolfsburg), a trio of restaurants and bars (Julian's, Seebiergarten am Maschsee, Allerlei), and Gestüt Brümmerhof, a thoroughbred stud farm established in 1989. A Mallorca subsidiary (BAUM Group Mallorca S.L.) develops luxury villas and fincas across 18 plots on the island. Revenue is generated through a mix of recurring residential and commercial rents, one-time property sales and fit-out works, hospitality and F&B operations, and joint-venture development fees (most recently a €15M Autohof Barmke project with AGRAVIS).
