Pouderoyen B.v.

What Pouderoyen B.v. does

Pouderoyen B.v., trading as Pouderoyen Tonnaer, is a Dutch professional-services advisory firm headquartered in Nijmegen and operating four offices (Nijmegen, Rosmalen, Voerendaal, Baexem). The firm consolidates two legacy practices under Aelmans Adviesgroep — Pouderoyen Compagnons (urban planning and landscape architecture, heritage dating to architect ir. Cees Pouderoyen in 1912) and Tonnaer Adviseurs in Omgevingsrecht (environmental law, founded by Frans Tonnaer in 1993) — which were combined under the current brand in 2020. Its core offering covers four interconnected service areas: spatial development (Ruimtelijke ontwikkeling), urban planning and landscape (Stedenbouw en landschap), environmental law (Omgevingsrecht, including the Omgevingswet), and environment and living environment (Milieu en leefomgeving — odor, air quality, health, nitrogen, GIS analysis). A separate Praktijkacademie delivers paid in-company training and workshops.

The firm generates revenue through project-based professional-services fees billed to clients across four primary segments: Dutch municipalities, provinces and national government; private developers, entrepreneurs and construction companies; housing corporations; and private individuals and landowners. Notable engagements include a 6,500-unit Herontwikkeling Winkelsteeg for Gemeente Nijmegen, a geurbeleid (odor-policy) framework for Gemeente Land van Cuijk developed with ZLTO/GGD/Milieuvereniging, an integrated gebiedsvisie through 2040 for Gemeente Alphen-Chaam, a Provinciaal Inpassingsplan for Provincie Noord-Brabant, and campus-housing zoning plans at TU Eindhoven. Distribution is sales-led and direct, with thought-leadership content (articles in Tijdschrift voor Omgevingsrecht, Praktijk Omgevingsrecht, Gemeentestem, Land- en Tuinbouwbulletin) and Praktijkacademie training supporting pipeline generation. As an independent division of family-owned Aelmans Adviesgroep (~200 employees, 11 locations), Pouderoyen Tonnaer has access to shared resources while remaining operationally self-standing.
