What BiermanHenket does

BiermanHenket is a privately held Dutch architecture firm founded in 1976 by Hubert-Jan Henket and headquartered at Landgoed Den Eikenhorst in Esch, near 's-Hertogenbosch in the Netherlands. The firm specializes in the restoration, renovation, transformation, and new construction of existing and monumental buildings dating from the 17th to 20th centuries, with deep expertise in Dutch modernist heritage (Rietveld, Wiebenga, Duiker). It is ERM-certified (Erkend Restauratie Architectenbureau) under the BRL1000, URL1001, and URL2001 guidelines, and maintains a quality manual comparable to ISO-9001. The practice is led since January 2024 by three partners (Janneke Bierman, Yvonne Segers, Joep van As) supported by a management team that includes Sander de Bruin and Wouter Habets, and comprises 50+ colleagues across architecture, interior design, restoration, technical design, BIM, and sustainability disciplines.

BiermanHenket's service offering spans the full project lifecycle — feasibility studies, cultural heritage assessments, schematic and definitive design, technical engineering, construction management (directievoering), and interior design — all executed through a BIM-centric workflow that integrates 3D visualization, virtual reality, and digital building passports. The firm has developed two proprietary innovations: the Duurzaamheidswiel (Sustainability Wheel), a methodology for visualizing sustainability trade-offs across five themes (material-bound energy, operational energy, social sustainability, nature-inclusive building, and reuse/recovery), and a digital building passport system supporting circular construction. Projects have produced measurable sustainability outcomes, including the Kruithuis's A++ energy label, Bastion Zuid's BREEAM Excellent certification, and WTC Rotterdam's BREEAM-in-use Very Good certification.

The firm's revenue model is project-based professional services, with fees structured around design phases and negotiated per engagement based on scope and complexity. Clients are concentrated in the Netherlands and span government (Rijksvastgoedbedrijf for the Tweede Kamer, municipalities), cultural institutions (Museum van Bommel van Dam, Beurs van Berlage, Anne Frank Huis), real estate developers and investors (Bouwinvest for WTC Rotterdam, Renschdael Groep), healthcare providers (Park Vossenberg), and other specialized sectors. The firm works across the entire Netherlands with one historical international engagement (Netherlands Embassy, Bangkok, 2007). Customer acquisition is driven by portfolio reputation, direct relationships, and public tender processes rather than marketing-led demand generation.

• Mecanoo: Dutch architecture firm headquartered in Delft with a comparable portfolio spanning new construction, renovation, and cultural/heritage projects.

• Bureau Polderman: Dutch architecture and restoration specialist working on monumental and heritage buildings across the Netherlands. Very directly comparable niche: ERM-equivalent heritage restoration expertise, similar firm scale, and shared focus on 17th–20th-century Dutch building stock.
• ZUS (Zones Urbaines Sensibles): Dutch architecture and urbanism practice of comparable scale with strong focus on adaptive reuse, sustainability, and public-sector commissions. Comparable positioning in Dutch public/cultural projects and shared emphasis on contextual design and heritage-sensitive transformation.

Highly comparable niche positioning to BiermanHenket's ERM-certified restoration practice and shared focus on Dutch modernist monuments.

Comparable in scale and in the integration of architectural design with monumental building contexts.
• Erick van Egeraat Architecten: Dutch architecture practice of similar scale to BiermanHenket, recognized for museum and cultural building design (e.g., Museum de Fundatie, glass facade additions to heritage structures). Comparable focus on integrating contemporary design with existing fabric, especially in the Dutch cultural-institution market.
• Powerhouse Company: Dutch architecture firm of comparable size, recognized for cultural, residential, and adaptive reuse projects. Shares the same Dutch design-firm identity, mid-sized structure, and focus on integrated architectural and interior design for public and cultural clients.
• DP6 architectuurstudio: Dutch architecture studio focused on cultural, educational, and heritage projects with a similar boutique scale. Comparable positioning in the Dutch public and cultural-institution market, with shared emphasis on thoughtful integration of new and existing fabric.

Broad incumbents

• MVRDV: Significantly larger Dutch architecture firm (Rotterdam) with broader geographic reach and a wide portfolio including cultural and public buildings. A scaled-up incumbent peer: overlapping in client segments and Dutch market presence, but operating across a wider range of typologies and geographies than BiermanHenket's specialist niche.
