Stöckli Grenacher Schäubli AG für Architektur Innenausbau Design

What Stöckli Grenacher Schäubli AG für Architektur Innenausbau Design does

Stöckli Grenacher Schäubli AG für Architektur Innenausbau Design, operating as C/O Architektur AG since 2025, is a privately held Swiss architecture firm headquartered at Waserstrasse 16, Zürich. Founded in 1983 and led by partners Michael Graf, Volker Mencke, and Franco Huber, the firm delivers full architectural services — design, planning, building analysis, Bauherrenberatung, Baumanagement, and Bauleitung — from initial feasibility through construction completion. Its portfolio spans new construction, renovation, heritage restoration (Denkmalschutz), and feasibility studies across residential, commercial, institutional, and religious typologies. The firm carries credentials and prior experience from Gigon/Guyer, Daniel Libeskind, and Stücheli Architekten among its partner roster.

The firm operates a project-based professional services model, acquiring work through open and invited architectural competitions (Wettbewerb), won study commissions (gewonnener Studienauftrag), and direct commissions (Direktauftrag). Clients include the Swiss federal government (Bundesamt für Bauten und Logistik BBL), ETH Zürich, VZ VermögensZentrum, PSP Properties AG, SGI Schweizerische Gesellschaft für Immobilien AG, and numerous Catholic and Protestant Kirchgemeinden across Zürich, Aargau, Thurgau, and Basel-Stadt. Its in-house carpentry workshop (Schreinerei), co-located above the atelier, enables integrated design and execution of custom millwork — a structural differentiator versus pure design practices that subcontract Schreinerarbeiten.

Headcount is approximately six employees, with an extended core team of up to nine including management and freelance contributors. Marketing channels are essentially absent: the firm relies on competition results, professional network referrals, and repeat institutional engagements rather than active outbound demand generation. Geographic focus remains domestic Switzerland, with project execution observed across the Zürich metropolitan area and Northern, Eastern, and Central Swiss cantons.
