Urhahn

What Urhahn does

Urhahn is a privately held Dutch urban design and strategy firm founded in 1991 by Gert Urhahn and headquartered at Henri Polaklaan 42 in Amsterdam. The firm operates as Urhahn Stedenbouw en Strategie B.V. with a foundation-based ownership structure through which employees participate as co-owners; current partners are Tess Broekmans, Ad de Bont, and Wendy van Kessel, supported by a team of approximately 15 staff including designers, researchers, and an office manager.

The firm's core offerings span five integrated services: stedenbouwkundig plan (urban planning), gebiedsvisie (area visions), ontwikkelstrategie (development strategies), beeldkwaliteitsplan (visual quality plans), and ontwerpend onderzoek (design research). Methodologically, Urhahn is anchored in the 'Spontane Stad' (Spontaneous City) framework published in 2010, which advocates flexible, user-centred, and participatory urbanism over rigid masterplanning. Practice areas are organised around three thematic pillars: stedelijke transformaties (urban transformations), samenleven (living together), and de gezonde en actieve stad (the healthy and active city). The technology stack is conventional urban design tooling, primarily Vectorworks and Illustrator, used for visualisation and scenario modelling rather than AI-driven analytics.

Urhahn's revenue model is project-based professional services consultancy, with fees negotiated per engagement against multi-year contracts. The firm serves Dutch municipalities (primary segment), housing corporations, property developers, and provincial/national government bodies including the Ministry of Infrastructure and Water Management and the Ministry of VWS. Client acquisition is relationship- and reputation-driven, supported by direct commissions, competitive public tenders, an open-access publication tradition, and Festival STAD, a biennial industry event co-organised with APPM, Stadkwadraat, de Mannen van Schuim, and STIPO. No revenue, funding events, or external investors are disclosed, and the firm remains domestically focused with no operational presence outside the Netherlands.
