What diederendirrix does
diederendirrix B.V. is a privately held Dutch architecture and urban design firm headquartered in Eindhoven with a second office in Rotterdam. Founded in 2005, the firm delivers two core service lines — Architecture (Architectuur) and Urban Design (Stedenbouw) — spanning new construction, renovation, repurposing, and ensemble building across residential, commercial, public, educational, and cultural typologies. It serves Dutch municipalities, real estate developers, housing corporations, universities, and corporate clients, with a documented emphasis on heritage transformation, large-scale mixed-use and residential projects, and sustainability/climate-adaptive design.
The firm operates as a project-based professional services practice. Revenue is generated through direct commissions and competitive tenders, with pricing structured per project rather than via published rate cards. Project sizes range from cultural venues and schools to residential towers up to 84m (Onyx) and 75m (De Bankier), and urban masterplans. Notable completed and ongoing projects include Witte Dame, Ketelhuis Ceres (BNA Beste Gebouw van het Jaar 2013), Qubit (TU/e, 2023), Hoogwegt headquarters (2020), Sixty5 (2020), Raadhuis Krimpen aan den IJssel (2018), Picuskade, De Bankier (2023), Diepeveen & Co (2023), and Eurostaete (in development). The firm leads multi-party consortia with Dutch landscape and urban design partners including Felixx, Buro Lubbers, DELVA, and West 8.
diederendirrix has no proprietary software platform or AI/ML capabilities; its technical backbone is BIM-enabled design (through affiliated technical-design unit bureauEAU). The firm is founder/partner-led, with co-founders Bert Dirrix and Paul Diederen (now in an advisory role) and current general director Theo Hauben. It is independently owned with no disclosed external investment, acquisitions, or parent company.

diederendirrix competitors and assessment
Company assessmentDirect peers
- Mecanoo: Dutch architecture firm with deep expertise in public, cultural, educational, and residential buildings, plus a strong track record in heritage and transformation projects. Closely comparable to diederendirrix in client mix (universities, municipalities, housing corporations) and design-led approach.
- UNStudio: Amsterdam-based architecture and urban design firm working across residential, mixed-use, and public buildings globally. Similar in offering (architecture + urban design) and in competing for large Dutch and international commissions in the same typologies.
- MVRDV: Rotterdam-based architecture and urban design firm with a similarly broad portfolio spanning residential towers, mixed-use developments, and masterplans. Directly comparable in geography (Netherlands HQ), disciplines (architecture + urban design), and typologies (large-scale residential, public, transformation).
- de Architekten Cie. Amsterdam-based architecture and urban design firm working on residential, mixed-use, and public projects across the Netherlands. Comparable in scale, typology focus (large residential and urban projects), and reliance on Dutch developer and municipal clients.
- KAAN Architecten: Rotterdam-based architecture firm with a comparable portfolio in cultural, public, and residential projects, including transformation and civic buildings. Similar size and market positioning to diederendirrix within the Dutch mid-market for design-led commissions.
- ZUS (Zones Urbaines Sensibles): Rotterdam-based practice for architecture and urbanism, with a strong portfolio in urban transformation, area development, and architecture. Direct overlap with diederendirrix on Dutch urban design and transformation commissions, particularly in the Randstad.
- Benthem Crouwel Architects: Amsterdam-based architecture firm known for public, transport, and cultural buildings, with a strong reputation in Dutch institutional design. Comparable in typology (public buildings, infrastructure-adjacent) and client base (government, public institutions).
- Jo Coenen & Co: Dutch architecture and urban design firm with a portfolio in cultural, public, and residential buildings, including masterplans and area transformations. Comparable in combining architecture with urban-scale visioning and in working with Dutch public and cultural clients.
Broad incumbents
- OMA: Office for Metropolitan Architecture, the largest and most internationally prominent Dutch architecture/urban design practice. Overlaps in residential towers, cultural buildings, and urban masterplans, but operates at a much larger scale with global reach; functions as a broad incumbent rather than a head-to-head peer.
Emerging players
- Powerhouse Company: Rotterdam-headquartered architecture firm with a growing portfolio in residential towers, mixed-use, and urban regeneration. Operates in many of the same Dutch cities and typologies as diederendirrix but with a more pronounced emerging/international orientation.
