Büll Family Office

Büll Family Office

The Büll Family Office emerged from the B&L Group, a Hamburg-based real estate developer and investor founded by Albert Büll roughly five decades ago. The B&L Group remains the operational core, specializing in office, residential, and specialty properties such as hotels and boardinghouses across Germany. The family office manages the wealth generated by these activities, alongside direct investments in companies and public equities, with Dr. Cornelius Liedtke having served as a long-term co-founder and business partner alongside Büll. Through the B&L Group, the family controls a directly-owned real estate portfolio of substantial scale. Confirmed holdings include the mixed-use Holzhafen Quarter on Hamburg's Große Elbstraße, the Kö-Bogen II commercial complex in Düsseldorf, the Hafenpark Quartier development in Frankfurt's Ostend district, and the Clipper Boardinghouses portfolio with assets in Hamburg and Berlin. The office's investment activities extend beyond concrete — confirmed strategies include direct investments, fund-of-funds commitments, and venture capital across sectors such as Energy Transition & Renewables, Mobility & Transportation, Industrial Tech, and FinTech. A known co-investment is in Encavis AG, a Hamburg-based wind and solar park operator. Day-to-day leadership falls to Tobias Krauss, who serves as CEO of Abacon Capital and Head of the Büll Family Office. While total professionals remain undisclosed, the family's influence extends into Hamburg's civic and sporting life: Albert and Christa Büll are prominent 'Gold' donors to the Förderkreis Internationales Musikfest Hamburg and members of the Norddeutscher Regatta Verein. The Albert Büll Stiftung handles charitable activities. In March 2026, the group's property management unit won an external mandate from AUG. PRIEN Invest, signaling continued expansion of its fee-earning services. The office's structural distinction lies in its simultaneous operation as both an active developer — constructing and managing large-scale German real estate projects — and a diversified allocator writing checks into external venture capital and private equity funds. This builder-owner-allocator model means deal flow can originate from construction site, tenant relationship, or fund manager, not just a traditional LP gatekeeper.
