What OLIVIER FOURNEAU ARCHITECTES does
Olivier Fourneau Architectes is a privately held Belgian architecture atelier (srl) founded in 1998 and headquartered at Rue des Augustins 34 in Liège. The firm operates as a nine-architect boutique practice specializing in contextual, heritage-sensitive new construction and renovation across residential, mixed-use, office, cultural, and public space typologies. Its practice is anchored by founder and gérant Olivier Fourneau, a restoration specialist who has taught at the Faculté d'Architecture de Liège since 2009, with a team bringing complementary credentials in PEB certification, urban planning, passive-house design, and timber construction.
The firm's revenue model is project-based professional services, sourced from two channels: (1) open and restricted public procurement competitions (appels d'offre) issued by Walloon municipalities, public housing funds, and government agencies; and (2) direct private commissions from individuals, developers, and corporate clients. Notable institutional clients include the Ville de Liège, ERIGES, and the Fonds du Logement des familles nombreuses de Wallonie; corporate clients include ETHIAS Assurances (18-site agency transformation), Urbaneo, Under The Roof, and Forestia. Project delivery is supported by recurring structural engineering, MEP, and scenography partnerships, including a co-architecture association with Bureau Fellin.
Geographically, OFA concentrates in Wallonia with a Liège-centric base while executing projects across Belgium including Brussels and Flanders via institutional programs. Its portfolio is repeatedly validated through regional and national awards — Grand Prix d'Architecture de Wallonie 2023, Grand Prix de l'Architecture et de l'Urbanisme de la Ville de Liège 2024, BigMat National Architecture Award 2025, and Brick Award 2026 finalist — as well as inclusion in ICA Inventaires and the firm's own 25-year monograph. Marketing is portfolio-driven via fourneau.eu, supplemented by earned media in architecture guides, RTBF Auvio video features, and competition-driven visibility.

OLIVIER FOURNEAU ARCHITECTES competitors and assessment
Company assessmentBroad incumbents
- Robbrecht en Daem architecten: Established Ghent-based practice with deep experience in cultural, public, and contextual architecture. Larger and more internationally renowned than OFA but operates in the same Belgian heritage-and-public-space niche and competes for similar institutional commissions.
- Caruso St John: European architecture practice internationally recognised for heritage restoration, contextual housing, and cultural projects. Comparable in heritage/restoration emphasis and award positioning, though larger and more international in scope.
Direct peers
- Office KGDVS: Belgian architecture firm with contextual, public-oriented portfolio across housing and cultural projects. Comparable atelier-size practice competing in similar Belgian public-tender landscape.
- agwA: Brussels-based architecture and urbanism firm working on contextual, heritage-sensitive projects including public housing and cultural buildings. Comparable to OFA in atelier size, Belgian public-sector focus, and award-driven positioning.

- Bovenbouw Architectuur: Antwerp-based architecture firm active in urban regeneration, residential, and public-sector projects in Belgium. Comparable in scale and in the typology of contextual Belgian public-housing and urban-renewal work.
- Bogdan & Van Broeck: Brussels-based architecture practice with a comparable profile: small-to-mid atelier, focus on heritage, contextual, and socially-engaged architecture, with significant public-housing and urban-regeneration commissions across Belgium. Most analogous Belgian peer for OFA in scale, typology, and institutional client base.
- de vylder vinck taillieu: Ghent-based atelier known for contextual, often unconventional architecture with strong public-sector presence. Similar atelier structure, comparable Belgian footprint, and overlapping client base in public and residential commissions.
- Stéphane Beel Architecten: Belgian architecture firm with strong portfolio in residential, public, and cultural architecture. Comparable atelier format, Belgian footprint, and award-recognised design quality.
