Heyligers Architects

What Heyligers Architects does

Heyligers Architects is a privately held Dutch architecture and interior design firm founded in 1988 by Willem Heyligers. The firm operates as a single integrated practice across two studios in Amsterdam (headquarters at Entrepotdok 164) and Utrecht (Nieuwekade 213–215), deploying a multidisciplinary team of approximately 20 architects and interior designers plus an average of two interns, jointly managed by partners Willem Heyligers, Lonneke Leijnse, and Marleen Valstar. The firm is ISO 9001 certified and a member of the BNA (Association of Dutch Architectural Firms), and co-founded the Refill network addressing vacant property reuse.

The firm delivers full-service architecture, interior design, and project management across the entire Dutch project lifecycle — from schetsontwerp (concept design) through bouwaanvraag (building applications), tendering, and uitvoering (execution). Its portfolio spans offices, restaurants, hotels, wellness centers, retail, private residences, and historic monumental buildings. Recurring specializations include office innovation (since 2000), sustainability certification expertise (BREEAM, LEED, GreenCalc+), and the transformation/repurposing of existing buildings — including the award-winning Diamantbeurs/Capital C renovation (MIPIM 2020 Best Refurbished Building) and the in-progress Berghaus Plaza Amsterdam (288 homes, 55,000 m2, targeting BREEAM Excellent).

Revenue is generated through project-based professional services fees, with clients acquired directly through relationships, referrals, industry reputation, and tender processes. Named clients include Round Hill Capital, Boelens de Gruyter, Kroonenberg Groep, Optiver, Aon, Bruna, Gemeente Amsterdam, Stichting Ronald McDonald Huis Emma, and Versmarkt Fresh, spanning real estate development, financial services, technology, retail, government, and nonprofit sectors. The firm markets through LinkedIn, Instagram, Pinterest, its website, trade publications (Architectenweb, vakblad Pi, Kroonenberg Journal, Parool), and industry events such as Provada.
