What a|sh architects does

a|sh architects (legal entity: sander.hofrichter architekten GmbH) is a German architecture firm founded in 1936 and headquartered in Ludwigshafen am Rhein, operating approximately 300 staff across nine offices in Germany and Switzerland. The firm specializes in complex, multi-year general planning (HOAI Leistungsphasen 1-9) for healthcare, educational, scientific, and public administration buildings, with deep expertise in hospital architecture and a 'hospital of short distances' concept, plus a Phase Zero participatory planning methodology for educational facilities.

Its core service offering is structured around six integrated practices: hospital and healthcare architecture (Krankenhausbau), educational building design (Bildungsbau), in-house medical and laboratory technology planning (Medizintechnik), fire protection (Brandschutz, operated via subsidiary a|sh Brandschutz GmbH), energy and sustainability planning (Energiefachplanung), and construction supervision (Objektüberwachung, ~40 staff). The technology backbone is BIM-based planning with database-supported equipment lists at 1:25 scale detail drawings, CAD, and fire protection-specific BIM tools, deployed across a modular team of specialists that can be assembled per project.

The firm operates a professional services revenue model with fees structured under the German HOAI framework. Go-to-market is exclusively enterprise public-sector field sales, with projects acquired through competitive procurement (VgV-Verfahren, VOF-Verfahren, Realisierungswettbewerb design competitions) and direct awards from hospitals, universities, research institutions, municipalities, and select corporate clients (e.g., BASF Medical Center, Wilo Health Cube). Customer relationships are anchored by reference projects such as Universitätsmedizin Mannheim, Universität Heidelberg research buildings INF 104/326, Universitätsspital Zürich Campus MITTE1|2, and Klinikum Coburg. The firm is privately held by its five managing directors (Prof. Linus Hofrichter, Torsten Petroschka, Martin Rieger, Nadine Schirmer, Peter Kuhl) with subsidiary leadership (Marco Bauer for Brandschutz GmbH) and no external institutional investors disclosed.
