Dorrhauer & Partner GmbH

What Dorrhauer & Partner GmbH does

Dorrhauer & Partner GmbH is a Swiss architecture, planning, and project management firm founded in 2013, headquartered in Hünenberg (Canton Zug) with a second office in Zürich. The firm specializes in commercial interior fit-out, tenant improvements, and construction management for property owners, tenants, and international corporates establishing or expanding operations in German-speaking Switzerland. Its full-service offering spans advisory, concept development, design planning, tendering, and execution oversight, with capabilities in workplace, restaurant, and retail fit-out, as well as M&E coordination and feasibility studies (including PV/rooftop solar and EV charging planning).

The firm operates a project-based professional services model, earning fees against defined scopes (planning, design, tendering, construction supervision). Engagement is anchored by long-running commercial clients such as Specialized Europe GmbH (relationship dating to 2015 with multiple projects) alongside project-based work for Sony Music, Google Zürich, Deloitte Zürich, General Motors, Savills, Knight Frank, Allreal, ZHAW, and Instant Group. The firm is owner-operated under Managing Director Daniel Dorrhauer and Architect/Prokuristin Mitra Dorrhauer, with approximately nine staff. The business is privately held with no external investors or funding rounds disclosed, no proprietary technology or AI capability, and geographic concentration in the cantons of Zürich, Zug, and Central Switzerland. The website is bilingual (German/English), reflecting engagement with both domestic and international clients.

The business is small, partner-led, and relationship-driven. Competitive advantage rests on track record, repeat commercial clients, and an established broker-referral ecosystem rather than technology, scale, or product IP. No R&D, no product roadmap, and no disclosed SaaS or platform component were identified in the input data.
