What de Alzua+ does
de Alzua+ is a French architecture and urban planning firm (SARL d'architecture) founded in 2002 by DPLG architects Jérôme de Alzua and Vanessa Barrois, headquartered in Lille with additional offices in Nantes and Santiago de Chile. The firm delivers full-service architectural design — from competition entry and concept through to construction supervision — for public-sector clients (municipalities, intercommunities, state entities, healthcare operators) and private developers (corporate headquarters, mixed-use programs, social and collective housing). Its portfolio spans public equipment, offices, collective housing, and urban requalification, with deep expertise in sustainable design including HQE (High Environmental Quality), BBC (low-energy building), and positive-energy certifications — notably the Archives départementales du Nord (first positive-energy archives building in France) and the convertible Parking-silo mutable de la Plaine Images in Roubaix.
The firm monetizes through project-based professional services fees negotiated per commission, with no disclosed public pricing. Its go-to-market is built on a competition-led acquisition engine: participation in prestigious European and French competitions (EUROPAN, réinventer.paris, Pyramides), direct commissions from public and private clients, and multidisciplinary consortia with tier-one partners (Kengo Kuma & Associates, BIG Bjarke Ingels Group, Architecturestudio, AIA Life Designers, ZigZag Architecture) for large-scale public projects. The firm has ~15 core architects plus an extended collaborator network, was awarded the Nouveaux Albums de la Jeune Architecture (NAJA) prize in 2004, and was ranked among the top 300 French architecture firms by revenue in D'Architecture 2017. Marketing is primarily earned-media driven through architectural press (Le Moniteur, D'Architecture, AMC, Archibooks) and exhibition presence at Pavillon de l'Arsenal, Cité de l'Architecture, and similar venues.
Ownership and control rest with the two founding partners, with no disclosed external funding, parent company, or institutional shareholders. Recent 2026 Lauréat wins include the Extension du siège de la Métropole Européenne de Lille (with Kengo Kuma), Banque de France Roubaix, and Hôpital de Felleries-Liessies, alongside active competition entries with BIG and Architecturestudio.
