Bischof Föhn Architekten

What Bischof Föhn Architekten does

Bischof Föhn Architekten (legal entity: BF Architektur AG, CHE-259.692.068 MWST) is a Zürich-based architectural firm founded in 2012 by Stephan Bischof and Norbert Föhn, both ETH Zürich-trained architects, joined in 2022 by Rico Traxler as a third member of Geschäftsleitung. The firm employs approximately 25 staff (per company website) and operates from Feldstrasse 133 in Zürich, delivering projects across six Swiss cantons: Zürich, Lucerne, Bern, St. Gallen, Graubünden, and Thurgau.

The firm provides comprehensive architectural design and planning services spanning feasibility studies, architectural competitions, execution and detail planning, and construction management. Its practice is built on an interdisciplinary approach combining digital BIM planning and 3D modeling with physical model-making and construction research on existing buildings (Bauforschung am Bestandesobjekt). The defining specialization is 'Bauen im Bestand' - the renovation, conversion, and adaptive reuse of historical and heritage-protected buildings, with a clear emphasis on sustainability and circular construction (ReUse). The firm has pioneered Netto-Null (net-zero) construction approaches, as demonstrated by the Kindergarten Manegg conversion project. Project categories include Schulbau und Bildungseinrichtungen (school and educational facilities), Wohnungsbau (residential, particularly for non-profit housing cooperatives), and Öffentliche Gebäude (public buildings including cultural facilities and police stations).

Revenue is generated exclusively through project-based professional services fees under Swiss SIA fee regulations. The go-to-market is sales-led and competition-driven: the firm acquires projects primarily through architectural competitions (Wettbewerbe) - both open and selective procedures - with documented first-prize wins across public and cooperative categories. Secondary channels include direct commissions (from housing cooperatives and private clients) and Planerwahl public procurement procedures. Customer segments span public sector/municipal clients (e.g., Stadt Zürich, Kantonsschule Küsnacht), non-profit housing cooperatives (Baugenossenschaften, including Baugenossenschaft Pro Familia Root), private clients for single- and multi-family residential, and heritage property owners. The firm holds no external institutional investment, operates as a tightly-held partnership, and channels its visibility through architectural press, exhibitions (including the Architekturmuseum Basel), ETH teaching positions, and competition-derived earned media rather than paid marketing.
