Atelier B2A

What Atelier B2A does

Atelier B2A is a French architecture firm (agence d'architecture) tracing its origins to 1932 and currently led by the fourth generation of the Bourgoin family, Vincent and Cyrille Bourgoin, with Marie-Estelle Bourgoin as gérante. The firm operates from three offices in Viroflay (Île-de-France), Montargis (Centre-Val de Loire), and Montbard (Bourgogne-Franche-Comté), and was reorganized in July 2022 from a liberal professional practice into a formal société under the Atelier B2A name. Its 15-16-person team includes accredited architects (HMONP, DE, DESA), ESTP-trained engineers, and administrative staff.

The firm delivers full architectural services from concept through construction supervision across public facilities (town halls, civic centers), sports complexes, healthcare buildings (notably EHPADs), educational facilities (schools, colleges, lycées), individual and collective housing, industrial buildings, heritage restoration, and places of worship. Technical differentiation rests on sustainable and energy-efficient design — biosourced materials including wood frame, straw, hemp-linen-cotton insulation, and earth brick — with documented HQE certification, RT 2012 compliance, and E3C2/E4C2 energy performance levels, including a 30% consumption reduction on social housing rehabilitation. Recent marquee projects include Lycée Joséphine Baker in Hanches (€39M), Lycée Saint Jean-Paul II in Sartrouville (€14.6M), Essity's Hall Volare at the Gien plant (€13.6M), and the rehabilitation of 359 social housing units at La Bolière in Orléans (€10.6M).

Atelier B2A earns revenue through professional services fees on architecture and project management contracts, structured as either fee-scale maîtrise d'œuvre or negotiated design-build arrangements. Go-to-market is enterprise field sales via public procurement (concours), tendering against regional and departmental governments, supplemented by private commissions for healthcare, industrial, and residential developers. The firm collaborates recurrently with major general contractors (Bouygues Bâtiment Centre Sud Ouest, SOGEA Centre) and a stable set of engineering partners (ECI, BSI, BETHERM, ORLING, PRIVAT CRESPEAU, Arcabois Ingénierie Bois). The firm is privately held, with no external institutional investors or funding rounds disclosed.
