What Ratio arkitekter does

Ratio Arkitekter AS is an Oslo-headquartered Norwegian architectural practice operating as a private limited company (aksjeselskap), formed in September 2010 through the merger of Medplan AS Arkitekter (founded 1991) and BGO Arkitekter AS (founded 1984). The firm employs 74-77 architects, interior architects, structural engineers, BIM specialists, and administrative staff, and positions itself as one of Norway's most experienced architectural practices within public-sector projects. Its core offering is full-scope architectural and interior design services for healthcare facilities (acute hospitals, psychiatric centers, university hospitals), educational and research buildings (universities, libraries, campuses), cultural and civic venues (concert halls, churches, museums), and multi-use municipal centers. Projects are typically delivered as lead-architect and project group manager mandates, often through architectural competitions and direct public procurement by clients such as Statsbygg, regional health authorities (Helse Sør-Øst, Helsebygg Midt-Norge, Vestre Viken), municipalities, and universities.

The firm's technology platform centers on BIM (Building Information Modeling), VDC (Virtual Design and Construction), and LEAN construction methodology, developed in collaboration with Stanford University and Porsche Consulting. Open BIM is used throughout the design and construction phases. The practice has built strong sustainability credentials, with multiple projects certified to BREEAM Excellent, BREEAM Very Good, passive house standard (NS3700), and energy class A. Notable achievements include St. Olavs Hospital Kunnskapssenteret — Europe's first passive house hospital, which won 7 of 10 categories at the 2014 Design & Health World Congress — and ongoing work on Livsvitenskapsbygget (Norway's largest university building at 97,000 m², BREEAM Excellent).

The business model is fee-for-service professional services, with revenue generated through architectural design, interior design, and interdisciplinary project management commissions. Fees are project-based, negotiated under Norwegian public-sector procurement regulations, and span multi-year contracts (often 5-15 years from competition to completion). The go-to-market relies on competition wins (limited and open) and direct engagement with public-sector clients, supplemented by industry awards, project publications, and a professional network built over decades. Customer concentration is high within Norwegian public healthcare, education, and government sectors, with the firm's largest contracts running into hundreds of thousands of square meters of developed space.

Direct peers

• Link Arkitektur: Major Scandinavian architecture firm headquartered in Norway. Active across healthcare, education, and public-sector buildings; partnered with Ratio on Nytt Sykehus Drammen, but competes for similar public-sector hospital and university mandates.
• White Arkitekter: Scandinavian architecture firm (Swedish roots, pan-Nordic operations) with strong track records in large public-sector healthcare and education buildings. Direct competitor for Norwegian and Nordic hospital and university commissions.
• LPO Arkitekter: Norwegian architecture practice focused on sustainable, public-sector, and cultural projects. Comparable in size and Norwegian public-sector orientation; formed part of the G8+ team with Ratio on the Regjeringskvartalet competition and competes in adjacent cultural and public-building mandates.
• Nordic Office of Architecture: Trondheim-based Norwegian architecture firm with overlapping healthcare, education, and cultural sector mandates. Directly comparable in scale, sector mix, and competition-based GTM; Ratio has partnered with them on St. Olavs but they are also direct competitors for the same public tenders.
• Arkitema Architects: Danish architecture firm with Norwegian presence, active in healthcare and public-sector projects. Partnered with Ratio on Sykehuset Innlandet and Sjukehuset Nordmøre og Romsdal; competes for Scandinavian public tenders.

Broad incumbents

• Snøhetta: Norwegian-founded global architecture and brand-design firm. Larger, internationally diversified, and broader in scope than Ratio, but directly contests large Norwegian public-sector cultural and institutional commissions.
• BIG (Bjarke Ingels Group): Danish-headquartered, globally operating architecture firm that increasingly contests large Nordic and European public-sector and healthcare commissions. Comparable scale of ambition though broader portfolio than Ratio.
• HDR Inc. Large global architecture, engineering, and consulting firm with an industry-leading healthcare architecture practice. Competitor for benchmark international hospital commissions and useful peer for international healthcare-design benchmarks.
• Henning Larsen Architects: Danish architecture firm (now part of Rambøll) with strong portfolios in public-sector and cultural buildings across Scandinavia. Directly comparable for large civic and institutional commissions; partnered with Ratio on Sørlandet sykehus sketch project.

Others

• Aas-Jakobsen: Norwegian multidisciplinary engineering consultancy specializing in structural and civil engineering for large public-sector buildings and bridges. Adjacent rather than directly competing — co-depends with Ratio on the same mega-projects (e.g., Regjeringskvartalet via G8+ team).
