What Niedermann Sigg Schwendener Architekten AG does

Niedermann Sigg Schwendener Architekten AG (doing business as "nusus") is a Swiss architecture firm headquartered in Zürich-Kreis 4 with a 9-person team and a project portfolio spanning 2004 through 2026. The firm delivers comprehensive architectural and general planning (Generalplanung) services across four core categories: Alter+Pflege (care homes, nursing homes, dementia wards, and senior residences), Wohnen (multi-family residential, cooperative housing, mixed-use), Schulen+Sport (primary and secondary schools, sports halls, kindergartens), and Dienstleistung+Gewerbe (community centers, parish centers, commercial buildings). Technical competencies include renovation of post-war heritage buildings, Minergie-standard sustainable construction, prefabricated timber (Holzbau), and hybrid wood-concrete construction methods, with project construction costs ranging from CHF 2.6 million (Werkhof Dübendorf) to CHF 46.5 million (Pflegeheim Länzerthus, Rupperswil).

The firm operates a sales-led, business-to-government model, acquiring commissions primarily through Swiss public architectural competitions (Projektwettbewerbe, Studienaufträge, selektive Wettbewerbe) and selective tenders, with occasional direct commissions (Direktauftrag) from repeat clients. Primary buyers are Swiss municipalities, cantonal governments, public institutions (schools, healthcare facilities), church organizations, and housing cooperatives that engage architects via formal SIA-standard procedures. Geographic reach spans 12+ German-speaking Swiss cantons (Zürich, Aargau, St. Gallen, Bern, Thurgau, Schaffhausen, Schwyz, Obwalden, Solothurn, Graubünden, Luzern, Zug, Basel). The firm has won over 15 first-prize or first-rank competition results, alongside a consistent track record of 2nd and 3rd rankings, indicating a strong position in the selective public tender market. Revenue is project-based professional services income; no fees, revenue figures, or company financials are publicly disclosed.

The firm's operating model relies on a stable network of project-based specialist partners: landscape architects (Lorenz Eugster, Haag, Krebs und Herde, Rotzler Krebs Partner, Ryffel+Ryffel, Sima Breer, Haag, david & von arx), structural/MEP/building-physics engineers (Heierli, LFS, HKG, Caprez, 3-Plan, Büro 3, SJB.Kempter.Fitze, HL-Technik, WKP, T&P Troxler, Abicht, Lauber), construction managers (B+P Baurealisation, Ixtegra, BGS & Partner, Baldinger, Bosshard, HSSP), and visualization partners (nightnurse, Studio12, Pyxel, indievisual, Mauro Caviezel). The partner-led studio structure is supplemented by joint ventures (ARGE with A.D.P Walter Ramseier Partner AG on Zentrum Tödi, Horgen) to bid on larger projects beyond solo capacity.
