What kathrinsimmen Architekten ETH SIA GmbH does

kathrinsimmen Architekten ETH SIA GmbH is a Zurich-based boutique architecture and general-planning practice with a team of five, operating under the DBA kathrinsimmen architekt:innen. The firm specializes in elderly care facilities (nursing homes, assisted living, dementia centers), multi-family residential developments, and—more recently—public institutional and commercial buildings, with completed projects spanning Swiss cantons including Zurich, Schaffhausen, Aargau, Bern, and Solothurn. Notable delivered work includes the Alterszentrum Bachwiesen in Ramsen (32 care rooms, CHF 8.6M) and the Alters- und Pflegeheim Seegarten in Hünibach (35 care rooms plus a 12-bed dementia station, built in four phases over 30 months under full operation, CHF 12M).

The practice operates as a general planner, delivering architecture from feasibility through construction supervision, with internally developed expertise in dementia-friendly design, phased construction under operating conditions, and Minergie energy standards. New project wins in 2025–2026 (Bank Avera in Hinwil, Doppelturnhalle Ramsen) point to a gradual broadening of vertical scope into commercial and educational infrastructure.

The business model is project-based professional services revenue, acquired through open and selective architecture competitions and direct commissions from foundations, municipalities, and private developers. Pricing is determined by project scope and SIA fee structures; no public pricing disclosure exists. The firm is privately held, with no institutional investors, no parent company, and no disclosed funding rounds. It competes in the Swiss German-speaking market primarily through its competition win record, ETH SIA credentials, and published work in MODULOR and SIA publications.

Broad incumbents

• Itten+Brechbühl AG: Swiss-wide architecture and general planning firm with significant elderly care and residential portfolio — broader and more established than the subject firm but a direct competitor in many of the same open competitions.
• Stücheli Architekten AG: Established Zurich architecture firm with broader portfolio across residential, commercial, and public buildings — larger incumbent operating in the same Swiss German-speaking market with overlapping general-planning capabilities.
• Burckhardt+Partner AG: One of Switzerland's largest architecture firms with broad coverage across healthcare, residential, and institutional sectors — broad incumbent that competes with the subject firm on the same public-sector competitions but at a much larger scale.

Direct peers

• Hosoya Schaefer Architects: Zurich-based boutique architecture firm of comparable size with Swiss/ETH roots, working on residential, infrastructure, and cultural projects across Switzerland — directly comparable in scale, geography, and competition-driven GTM.
• Gigon Guyer Architekten: Well-established Zurich architecture firm active in cultural, residential, and renovation projects across Switzerland — comparable in Zurich market positioning and competition-based practice, though at a more mature size.
• EM2N Architekten: ETH-founded Zurich boutique architecture firm working on cultural, residential, and public-sector projects through competition-based acquisition — directly comparable boutique practice with similar SIA-affiliated profile.
• Burkhalter Sumi Architekten: Zurich-based boutique architecture practice with comparable size and competition-driven project acquisition model, focusing on residential and public buildings across German-speaking Switzerland.
• Schneider & Schneider Architekten: Aarau-region Swiss architecture firm with comparable boutique size and focus on public-sector, residential, and complex renovation projects acquired through competitions — closely matches the profile of a small SIA-credentialed Swiss practice.
• Abegg Hunziker Architekten: Zurich boutique architecture practice active in residential and care-sector projects across Switzerland — directly comparable in scale, vertical expertise, and competition-based GTM model.

Others

• Gross Generalunternehmung AG: Swiss general contractor and developer partnering with the subject firm on multiple joint competition entries (Seegarten Hü nibach, Pflegeheim Wisli, Mehrfamilienhaus Funkwiesenstrasse) — relevant ecosystem participant rather than direct competitor, but comparable visibility into Swiss care/residential construction cycles.
