What Staehr+Partner Architekten does

Staehr+Partner Architekten mbB is a Berlin-based architectural practice founded in 2003 by Henrik Stæhr, operating as a Partnerschaft mit beschränkter Berufshaftung (mbB) under German law. The firm employs approximately 20 architects and engineers and delivers comprehensive architectural and planning services across all HOAI Leistungsphasen (1–9), from feasibility studies through construction supervision. Its project portfolio is concentrated in residential developments (multi-family housing, urban infill, roof extensions, core renovations), vacation and resort properties, healthcare and senior living facilities, and selective public-sector commissions, primarily across Germany with a Berlin and Baltic coast focus.

The firm's technical capabilities are distinguished by expertise in Scandinavian-influenced design philosophy, DGNB-certified sustainable building consulting, multi-story timber construction (Vollholz, Brettsperrholz, Brettschichtholz), hybrid steel-timber structural methods, and heritage-listed building refurbishment. Notable technical achievements include a 7-story timber-frame building constructed over existing underground parking and floating-house resort planning. The practice operates without proprietary software platforms, with differentiation resting on specialized human expertise rather than technology platforms.

Revenue is generated through professional service fees structured per HOAI guidelines as percentage-of-cost or fixed-fee project commissions, acquired via direct client relationships, referrals, and invited architectural competitions. The firm serves a diversified base of private real estate developers (HELMA, BPD, The Grounds, hedera Bauwert, BAMAC, BUWOG, Esplanaden), public-sector clients (Berlin district governments), healthcare operators (Die Heilsarmee, Privatklinik am Tegernsee), and hospitality clients (CARAT Hotel Grömitz). Following founder Henrik Stæhr's departure in June 2025, the firm is now jointly led by partners Katja Steiger and Ingmar Horst.
