BAU Architectenbureau

What BAU Architectenbureau does

BAU Architectenbureau (legal entity B.A.U. Architectenbureau B. & C. Coussée bvba) is a family-owned Belgian architectural and urban planning practice founded in 1961 in Roeselare, West Flanders, by Carlos Coussée and currently led by his son Bart Coussée (joined 1997). The firm provides integrated architectural design services across three primary project categories: residential developments (apartments, multi-family housing, vacation properties), commercial and office buildings, and public-sector buildings including healthcare facilities, schools, and sports complexes. Clients include real estate developers (Karthuizer Development, CBS Development/Extensa, East Coast Invest, POC Partners, SELECTA INVEST, GTS 2), public entities (Zorgbedrijf Roeselare, Scholengroep St. Rembert), and private enterprises, with the geographic footprint anchored in the Belgian coastal region and West Flanders, supplemented by occasional international projects in Sardinia, Switzerland, Germany, and Spain.

The technical stack centers on Building Information Modeling (BIM) for virtual representation and data exchange with external partners during design and construction, complemented by in-house coordination of technical engineering systems (heating, sanitation, ventilation, electricity) and ongoing construction cost monitoring throughout project lifecycles. Delivery is supported by a small multidisciplinary team of approximately 8 architects, assistant architects, interior architects, and administrative staff operating from a single headquarters at Handelsstraat 78 in Roeselare.

The firm operates on a project-based professional services model with custom fee quotes per engagement tied to scope, size, and complexity, typically structured as multi-year contracts spanning design through construction supervision. Distribution relies on direct enterprise/client engagement, supplemented by project-dedicated websites, professional social media presence (LinkedIn, Facebook), and earned media via regional architecture publications (STERCK magazine West-Vlaanderen). The firm is a GDPR-compliant Belgian bvba (private limited company), with no external institutional investors or parent company involvement disclosed, and has accumulated 60+ years of continuous operation including a 2017 laureate win on the WZC Sint Henricus public healthcare competition.

Direct peers

• Gras architecten: Belgian architectural firm with a similar profile of residential, commercial, and public projects. Direct competitor in the Flemish market with comparable firm size and project typology.
• Stéphane Beel Architects: Belgian architectural practice known for cultural and residential projects. Comparable in being a focused Belgian studio with strong design reputation, though typically at a higher market tier in terms of public recognition.
• B2Ai: Multi-disciplinary Belgian architecture and engineering firm offering integrated design services across residential, commercial, healthcare, and public buildings. Direct competitor in the Belgian market with broader geographic reach but similar full-service value proposition.
• Bontinck Architecture & Engineering: Belgian multi-disciplinary architecture firm combining architecture and engineering services, similar in size and integrated approach to BAU. Operates in the same Belgian market with comparable residential, commercial, and public sector project portfolio.
• a2o architecten: Belgian architectural firm with strong portfolio in residential and public buildings. Competes with BAU for similar public-sector and developer-led projects in Belgium.

Broad incumbents

• Arcadis Belgium: Global design and consultancy firm with strong Belgian presence in architecture, urban planning, and engineering. Competes for public tenders and large developer commissions across the same geographies as BAU.
• de Architekten Cie. Established Dutch/Amsterdam-based architectural firm with broad portfolio in residential, commercial, and urban planning. Larger and more international than BAU, but operates in adjacent Benelux markets with overlapping client profiles.
• Mecanoo: Dutch architecture firm with extensive experience in residential, healthcare, and public buildings (including care homes). A larger competitor that has executed major Belgian and European projects similar to BAU's portfolio.
• Sweco Belgium: European engineering and architecture consultancy with significant Belgian operations. Competes for public-sector and large-scale projects where BAU's integrated engineering approach is most relevant.

Others

• Bureau Bouwtechniek: Belgian technical engineering consultancy specializing in building physics, MEP coordination, and BIM. Adjacent rather than directly competing; covers technical engineering services that BAU performs in-house, illustrating alternative sourcing models in the Belgian market.
