Architekten Kollektiv

What Architekten Kollektiv does

Architekten Kollektiv is a Swiss architecture collective founded in 1996 in Winterthur, Switzerland, by six artists/architects. The firm provides full-service architectural design, planning, and project management across five principal project categories: residential buildings (Wohnen), public facilities (Öffentlich), commercial/service buildings (Dienstleistung), sacred architecture (Sakralbauten), and heritage conservation (Denkmalpflege), as well as participation in architectural competitions (Wettbewerbe). Service offerings span new construction, renovation, conversion, heritage preservation, and urban planning, with particular expertise in sustainable wood construction methods and the conservation of listed buildings.

The firm operates through a project-based professional services model, generating revenue from architectural fees calculated as a percentage of construction costs or fixed fees for specific project phases. Work is acquired through participation in open and invited architectural competitions (Projektwettbewerbe and Studienaufträge) and direct commissions. The customer base is diversified across municipal and cantonal governments (Stadt Winterthur, Stadt St. Gallen), housing cooperatives (HGW, BVK, gaiwo), religious institutions (Kirchgemeinde Winterthur), and private clients, with an active portfolio of over 100 documented projects concentrated in the Winterthur region and broader Northern/Eastern Switzerland.

The collective structure brings together multiple architects with diverse specializations, enabling the firm to deliver projects across heterogeneous building types. Operations are supported by an established ecosystem of engineering partners (B3 Kolb AG for structural engineering, Bakus Bauphysik for building physics, Hunziker Partner AG for HVAC, Scherler AG for electrical), landscape architects (Ryffel + Ryffel, Graber Allemann, Schweingruber Zulauf), and visualization studios (nightnurse images, DesignRaum GmbH). The firm maintains a 6-person team and a portfolio website that serves as its primary marketing and documentation channel.
