What Studio Trachsler Hoffmann Architekturbüro does

Studio Trachsler Hoffmann GmbH is a privately held architecture firm headquartered at Flurstrasse 56 in the Altstetten district of Zürich, Switzerland, operating with approximately 8 employees under joint principals Gian Trachsler and Daniel Hoffmann. The firm delivers architectural competition services (Wettbewerb) and study commissions (Studienauftrag), specializing in urban neighborhood completion (Quartierergänzung), residential settlements (Wohnsiedlung), and mixed-use residential and commercial developments. Its portfolio spans Zürich, Basel, Samedan, and Konstanz (Germany), with documented first-prize wins at VoltaOst (Basel, 2016), Kochareal Baufeld C (Zürich, 2018), Tulpenweg (Zürich, 2021), Aegertenstrasse and Schärenmoosstrasse (Zürich, 2022), and Badenerstrasse (Zürich, 2024) and Reinacherstrasse (Basel, 2024).

The firm generates revenue through project-based commissions acquired primarily via Swiss architectural competitions and direct institutional engagement. Pricing is project-by-project; no public pricing exists. Client segments include public and institutional property developers (e.g., Immobilien Basel-Stadt), housing cooperatives (e.g., Bau- und Wohngenossenschaft Kraftwerk1), housing associations (Baugenossenschaften), and investment foundations (Anlagestiftungen). The practice repeatedly partners with specialist landscape architects — Atelier Loidl Landschaftsarchitekten, S2L Landschaftsarchitekten, Bernhard Zingler Landscape Projects, and EDER Landschaftsarchitektur — and with architecture firm Studio Burkhardt for joint competition entries. Execution mandates currently extend from 2019 through 2029, and the firm is recruiting an intern for September 2026, signalling active capacity build against the existing project book.

Revenue is not publicly disclosed. The underlying technology base is conventional architectural practice — design authoring, competition visualization (e.g., credited visualizer Besa Zajmi), and on-site construction execution — with no AI/ML capabilities, digital platform, or proprietary software product. Marketing and distribution are handled through the firm's website (trachslerhoffmann.ch) and competition participation, with no formal sales motion or social-media presence beyond the project portfolio. The firm has no subsidiaries, no external investment, and no parent company, operating as a founder-managed GmbH.
