What Factor Architects does

Factor Architecten b.v. is a Dutch architectural firm founded in 1974 and headquartered in Duiven, Gelderland, the Netherlands. The firm delivers full-service architectural design for a horizontal mix of building types, including holiday resorts and bungalow parks, water treatment and distribution infrastructure, schools and civic buildings, social housing and care complexes, and industrial or commercial facilities. Its specializations center on biobased and circular material application, modular and relocatable construction, integrated multidisciplinary design, and floating/amphibious housing — the last of which traces back to the first amphibious houses in the Netherlands developed at Maasbommel. Factor Architecten is part of IA Groep, a multidisciplinary engineering group that combines architecture, structural engineering, electrical engineering, and mechanical engineering under one parent, allowing most projects to be executed as integrated design packages.

Underlying capability rests on a portfolio of more than 60 documented projects across the Netherlands and selected European and international locations (Switzerland, Germany, Indonesia), supported by accreditations such as BREEAM and industry awards including the Zoover Award 2014, Water Wonen & Ruimte Award 2010, Stentor Publieks-Architectuurprijs 2007, and Parkvakanties Award 2026. Technical differentiators include concrete buoyancy body systems for amphibious housing, modular construction methods described by the firm as 'slim, snel, schoon en maximaal circulair' (smart, fast, clean, and maximally circular), and design integration with biobased or recycled materials.

The business model is professional services, project-based, with fees determined per commission based on scope, complexity, and phase coverage — from feasibility and conceptual design through technical elaboration, construction supervision, and maintenance planning. Go-to-market is enterprise field sales: projects are secured through direct relationships, public tenders, and repeat commissions with institutional clients including water companies (Vitens, Oasen, WMD Drinkwater), recreation park operators (Landal GreenParks, Dormio, Roompot), housing corporations (Sité Woondiensten, De Woonplaats), developers (Van Wijnen, Klaassen Vastgoedontwikkeling), schools, and municipalities. Pricing is not publicly disclosed; revenue is not reported; and the firm operates as a private limited company within IA Groep with no external funding events on record.
