What Leclercq Associes does

Leclercq Associés is a French architecture, urbanism, and landscape design firm headquartered in Paris with a secondary office in Marseille. Founded by François Leclercq, the firm has operated for over 30 years using a "transversal" methodology that integrates architecture, urban planning, and landscape design as a single discipline rather than three separate practices. The firm employs approximately 76 multidisciplinary professionals — architects, engineers, geographers, urbanists, graphic artists, designers, and mock-up artists — and serves two primary customer segments: French public institutions (municipalities, regional councils, government ministries) requiring schools, sports facilities, and public infrastructure, and private real estate developers (notably Woodeum/BNP Paribas and Alios Développement) seeking sustainable, high-design commercial projects.

The firm's core technical differentiators are in low-carbon and bio-sourced construction, most notably Cross-Laminated Timber (CLT) solid wood building systems developed with technology partner WO2, bioclimatic design using geothermal energy covering up to 80% of heating and cooling needs, and bio-sourced materials including raw earth and rice straw. The firm holds BIM management capability and has delivered projects certified to BBCA Level Excellent, HQE Level Excellent, and BREEAM Very Good standards. Signature projects include the Arboretum campus in Nanterre (125,000 m², Europe's largest solid wood office campus, €212M total works), INSEP Sports Center in Paris, Nelson Mandela High School in Nantes, Les Grandes Serres de Pantin, and the ongoing La Grande Motte Ville-Port urban redevelopment.

The firm operates a professional services, project-based revenue model, winning work through competitive public tenders and architectural competitions, supplemented by direct commissions from private developers. Fees are negotiated on a per-project basis and contracts are typically multi-year, reflecting the long design and construction timelines of large public infrastructure and commercial real estate. Distribution is achieved through a combination of public procurement (the primary channel), direct client engagement, and referral-based repeat business, supported by thought-leadership activities including conference lectures, journal publications, and industry awards. The firm is structured as a SAS (Société par Actions Simplifiée) with €200,000 in share capital and operates without any identified parent company or external institutional investment.
