THAMM & PARTNER

What THAMM & PARTNER does

THAMM & PARTNER GmbH is a privately held German real estate company (GmbH) headquartered in Berlin that specializes in monument-protected (Denkmal) residential real estate in prime inner-city locations. Founded out of predecessor Munich operations in 1982 and formally incorporated in Berlin-Charlottenburg in 1995 (HRB 56504), the firm operates under managing director Angela Thamm and has been active in the heritage property segment for over 30 years. The company holds a portfolio of 60+ historic properties across Berlin, Potsdam, Leipzig and Görlitz, with a balance sheet exceeding 75 million EUR and an equity ratio of approximately 80%.

The business operates a dual strategy. The first leg acquires, modernizes and resells "stylish old buildings" for trading profit, with sales executed through the dedicated portal www.ThammImmobilien.de. The second leg acquires and faithfully restores historic buildings to be held as long-term own assets, generating rental income and above-average asset value appreciation. The firm's most prominent recent development is HAFEN EINS in Leipzig-Lindenau — a 56-apartment plus 1 commercial unit waterfront project that won the BDA Architekturpreis Sachsen 2021 and the Architekturpreis der Stadt Leipzig 2022. A third, parallel line of activity is the issuance of silent partnership participations (stille Beteiligungen) on the open capital investment market via exclusive distribution partner IVM GmbH, providing non-dilutive growth capital.

The company serves high-net-worth individuals interested in capital investment in solid German Mittelstand enterprises and in heritage real estate, as well as buyers seeking character properties in protected historic buildings and institutional investors accessing the portfolio through silent partnerships. Distribution is direct and owner-led: the company website, the ThammImmobilien.de portal, project-specific sites, the BlickPunkt newsletter series, and architectural press coverage form the primary marketing surface. There is no disclosed technology platform, no headcount data, no venture or growth-equity funding, no M&A activity, and no public listing.

Expansion highlights5 records

Broad incumbents

• Vonovia SE: Europe's largest residential real estate company with a substantial German portfolio across urban and regional markets. Comparable on residential real estate activity in Germany, but operates at vastly greater scale with a different (broad-market, institutionalized) strategy than THAMM & PARTNER's heritage focus.
• Patrizia AG: European real estate investment manager and owner with strong German residential and urban investment activity. Comparable as a German urban real estate operator, though Patrizia runs investment management services at scale rather than focused heritage curation.
• Grand City Properties: European residential specialist with a sizable German portfolio focused on B cities and value-add repositioning. Comparable on German urban residential, including Leipzig exposure, but operates as a public REIT at very different scale than THAMM & PARTNER's private, curated model.
• LEG Immobilien: German residential real estate company focused primarily on North Rhine-Westphalia with a portfolio of approximately 165,000 units. Comparable as a German residential landlord, but its broad-market, large-scale focus contrasts with THAMM & PARTNER's curated heritage approach.
• Adler Group: German residential real estate company owning and managing approximately 70,000 units across Germany. Overlaps with THAMM & PARTNER on German residential activity but pursues volume-driven, value-add strategy rather than heritage curation.
• Deutsche Wohnen: One of Germany's largest residential property owners and managers, focused on urban housing in Berlin and other German metropolitan areas. A broad incumbent that overlaps with THAMM & PARTNER on Berlin residential stock but operates at institutional scale rather than a heritage niche.

Regional players

• Heimstaden AB: Swedish-headquartered residential real estate company with a meaningful German portfolio. Comparable on European residential ownership strategy but operates across multiple European countries rather than curating a German heritage-focused portfolio.

Emerging players

• Cureus GmbH: German residential developer building new senior-friendly and family apartments across German metropolitan regions. Comparable on German residential development and operational execution, though Cureus focuses on new-build rather than heritage restoration.
• ZIEGERT Group: Berlin-based real estate company specializing in premium residential brokerage and development in prime Berlin locations. Closely comparable on the curated, prime-location residential focus, with shared emphasis on high-quality urban Berlin product.

Direct peers

• Berlinovo GmbH: Berlin-based residential real estate company managing and developing housing stock in Berlin and other German cities. Directly comparable to THAMM & PARTNER on Berlin-centric residential activity, though publicly-owned and broader in tenant base than the heritage niche.
