Projekt 3 Architektur GmbH

What Projekt 3 Architektur GmbH does

Projekt 3 Architektur GmbH (operating as P3 Architektur) is a small, founder-owned Swiss architecture firm headquartered in a converted 1935 workshop ('Boltshauser') at Frauenfelderstrasse 45 in Weinfelden, Thurgau. The practice was founded by Thomas Gähwiler (Dipl. Architekt FH/SIA, MAS REM) and Andreas Helbling (Dipl. Architekt FH) and operates with a team of approximately nine professionals, including five architectural drafters, a project manager, a Bauleiter in training, and a member of the Geschäftsleitung.

The firm delivers three core service lines organized by project type: Neubauten (new residential construction including single- and multi-family homes), Umbauten (conversions and renovations including barn conversions, attic expansions, and energy-efficient retrofits under Minergie standards), and Gewerbe (commercial premises such as insurance agencies, healthcare facilities, and auto dealerships). These are supported by cross-cutting planning and project services covering needs analysis, project development, execution planning, Bauleitung (construction supervision), and Baudokumentation (building documentation for pre-sale or pre-renovation assessment). The practice acts as central coordinator and trusted representative for clients across multi-party construction processes.

Revenue is generated on a project-based professional services model, with multi-year commissions spanning from planning-only or construction-management-only partial mandates to full-scope projects, all quoted on project-specific terms. The customer base is regionally concentrated across the Thurgau canton and adjacent eastern Swiss municipalities, blending private residential homeowners with selected commercial and institutional clients (e.g., Die Mobiliar, VOLVO Weinfelden, Spitex Weinfelden, Pensionskasse Thurgau). Distribution relies on direct client engagement, a project portfolio website, and referrals through membership in Altbauweise Thurgau and Swiss Engineering, with one joint venture (ARGE with MGH_ARCHITEKTEN) executed for a larger mixed-use mandate.
