OOS

What OOS does

OOS AG is a Zurich-based architecture and design firm (Aktiengesellschaft, privately held, founded 2000) operating with a headcount in the 11-50 range and a single headquarters at Hardstrasse 245, Zurich. The firm delivers four core service lines — Architecture, Interior Architecture, Urban Planning/Master Planning, and General Planning — applied across residential, commercial, healthcare, hospitality, public-sector, and cultural typologies. Its project portfolio includes 94+ documented engagements on its website spanning remodeling, expansion, repositioning, new building, and site/area development, with named clients such as Andermatt Swiss Alps AG, Nest Sammelstiftung, Coca-Cola HBC Schweiz AG, Kühne Real Estate AG, SBB AG (Swiss Federal Railways), Hochgebirgsklinik Davos, Mobimo Management AG, and Viva Hub AG.

The firm's working technology stack is conventional architecture tooling — ArchiCAD for BIM and Grasshopper for parametric/scenario modeling, used selectively for urban planning and facade optimization — with no proprietary software, AI/ML systems, or platform products disclosed. The firm differentiates on a 'Clever Architecture, Clever Interiors, Clever Cities' philosophy emphasizing life-cycle thinking, sustainability (e.g., cited CO2 reductions up to 62% via wood construction in a geriatric facility), and integrated architecture-plus-interior delivery.

Revenue is project-based and commission-driven, structured around project scope, complexity, and duration rather than a standardized pricing model. GTM is sales-led, with new business sourced from design competitions (e.g., Swiss Pavilion EXPO 2020 Dubai, Medizincampus Davos masterplan), repeat enterprise commissions (developers, pension funds, healthcare operators, railways), and public procurement. Revenue, funding, and headcount trend data are not disclosed in available sources.
