Koen van Velsen Architecten

What Koen van Velsen Architecten does

Koen van Velsen Architecten is a privately held Dutch architecture practice founded in 1970 and headquartered in Amsterdam. For more than fifty years the firm has delivered site-specific design across cultural, residential, healthcare, education, infrastructure, office, urban design, landscape, and restoration/renovation projects, both domestically in the Netherlands and internationally in Belgium, Denmark, and Switzerland. The practice deliberately rejects a signature style, instead developing a unique design concept for each project based on location, programme, budget, and user requirements, with emphasis on spatial quality, experiential architecture, and detailed craftsmanship carried from concept through execution.

The firm operates on a traditional architectural services model. Revenue derives from project-based design fees, with the majority of large commissions secured through competitive public tendering for government clients — primarily Dutch municipalities, NS (Nederlandse Spoorwegen), and ProRail — together with direct commissions from private residential and cultural clients. Distribution is via competitive tenders (domestic and international), direct private engagement, and a project portfolio website that functions as the principal marketing channel; the firm does not resell, franchise, or license technology. Work is delivered by an in-house team of 11–50 professionals, with visualisation support subcontracted to external rendering studios.

Customer concentration sits primarily in the Dutch public sector, especially transport infrastructure (OV Terminal Breda, Station Groningen, Galecopperbridge), supplemented by healthcare (Groot Klimmendaal rehabilitation centre), cultural (Rijksakademie, University Museum Utrecht), and residential work (Huis op Zuid). The practice has accumulated extensive recognition — multiple BNA Best Building of the Year awards (2010, 2017), four EU Prize for Contemporary Architecture (Mies van der Rohe) nominations, a World Architecture Festival Health Building award, the Mart Stam Prize, and the BNA Kubus oeuvre prize — driven in part by founder Koen van Velsen's roles as Dutch Railroad Architect (2009–2015), acting Government Architect (2015), and Chief Advisor for Spatial Quality & Design at Amsterdam Zuidasdok (2016–2024).
