What BLRM Architects does

BLRM Architekt*innen is a Hamburg-based architecture firm founded in 2002 (originally as blauraum Architekten) and rebranded to blrm in 2022. The firm employs approximately 40 architects and operates from a converted community house in Hamburg St. Pauli. It provides architectural design, urban planning, general planning coordination, feasibility studies, and sustainability consulting across all HOAI work phases. Its practice is organized around three guiding principles — Transformation (adaptive reuse and densification), Circularity (buildings designed as material reserves), and Reduction (modular, efficient construction) — and applies Building Information Modeling as its primary collaborative methodology.

The firm serves a predominantly German client base spanning municipal housing companies (Stadtbau Würzburg, ProPotsdam, Gewobag), public transit operators (Hamburger Hochbahn AG), private developers (ECE, evoreal, DC Commercial, Aurelis), and municipalities. Projects are acquired primarily by winning architectural competitions and through direct commissions; notable recent first-prize wins include the U5 Arenen and U5 Hauptbahnhof stations and Bahnhofsquartier Leverkusen. BLRM is currently piloting an Integrated Project Alliance (IPA) delivery model at NOVO Bremerhaven, embedding architecture, interior design (includi), and construction (baubüro eins) into a single co-located team from project inception.

Revenue is generated through HOAI-regulated professional service fees on competition entries, design contracts, and full general planning mandates. Pricing is project-specific and negotiated per engagement; no public pricing exists. The firm does not raise external capital, operates without a parent company, and is governed by four managing partners (two co-founder professors and two promoted partners). A sub-brand, auau, was established to support architectural discourse and creative exchange distinct from the commercial practice.
