Project 310

What Project 310 does

Project 310 is a Toulouse-based architecture firm founded in 2009 by Christophe Balas, operating as a privately held SARL (Société à Responsabilité Limitée, RCS Toulouse 509 770 764) with a six-person team. The firm delivers public and cultural buildings, childcare and educational facilities, social and participatory housing, healthcare centres, and urban planning projects across the Occitanie region of France, with individual project contract values ranging from €250,000 to €9,000,000 HT. Revenue is generated through architectural commissions won primarily via French public procurement competitions (concours) and direct commissions from municipalities, intercommunal structures (communautés de communes), départements, and social housing providers (HLM / OPH). The firm's project portfolio spans cultural infrastructure (La Halle des Machines, €8.5M, 2014; Les Granges de Saint-Jean, €3.24M, 2018), social housing (Les Berges de Négogousses, €4.2M, 2014; La Place des Hauts Murats, €3.45M, 2020), healthcare (La Bastide verticale, €1.516M, delivered April 2025), and participatory housing (L'envolée, BDO Or certified).

The firm's core methodology is grounded in bioclimatic and low-carbon design — leveraging passive solar gain, natural ventilation, rammed earth, compressed earth blocks, straw insulation, bio-sourced timber, and locally sourced terracotta — supported by full BIM project delivery using ARCHICAD with IFC interoperability since 2006. Project 310 holds Pro-paille certification, is a member of Envirobat Occitanie (renewed for 2026), and has achieved BDO Or (Bâtiment Durable Occitanie Gold), HQE, BBC, and E4C1 environmental certifications on individual projects. The firm's go-to-market is sales-led and competition-led: it maintains a corporate website segmented for Particulier, Professionnel, and Institutionnel contacts, and gains new work through public tenders and the professional reputation of its founders within the regional Occitanie procurement ecosystem.

Project 310 is co-founding member of the La Vigie collective, an association of approximately 23 cross-disciplinary professionals (architects, urbanists, landscape architects, engineers, economists, colour designers) housed at Hôtel Virebent, Place de la Patte d'Oie, Toulouse. Christophe Balas simultaneously serves as Architecte Conseil de l'État for the DDT du Lot and President of AMO Occitanie Midi-Pyrénées, anchoring the firm's positioning within regional public-procurement and architectural-policy governance. The firm has received multiple recognitions, including the Prix d'Architecture Midi-Pyrénées 2013, the Trophées de la Construction 2023 Jury Prize and Healthcare Trophy, and the AMI 'Engagés pour la qualité du logement de demain' laureate.

Regional players

• Bureau Architecture Méditerranée (BAM): Southern France-based architecture firm focused on public facilities, social housing, and bioclimatic design in the Mediterranean region. Comparable typology and client base, but primarily operates in PACA rather than overlapping directly with Project 310's Occitanie territory.

Direct peers

• DGT Architects: French architecture practice with recognised expertise in social and sustainable housing, including work with major HLM operators and municipalities. Comparable in scale, sustainability orientation, and public-sector client base.
• Atelier Roland Schweitzer: French architecture and urban planning practice with a long track record in public-sector projects, landscape integration, and bioclimatic design. Comparable on humanist design philosophy, public client base, and integrated urban/architectural practice.
• NP2F Architectes: French architecture practice operating across cultural, educational, and social housing typologies, frequently engaged in public tenders. Comparable project scale, mixed public/private client base, and design-led positioning.
• MU Architecture: French architecture firm with a strong portfolio in social housing, urban renewal, and participatory housing, particularly in the Occitanie and southwestern France regions. Directly comparable on social housing typology and public client mix.
• Atelier Philippe Madec: Paris-based French architect specialising in bioclimatic, sustainable, and low-carbon public architecture, with a comparable portfolio of municipal, cultural, and social housing projects. Closely aligned with Project 310's humanist, environmentally committed positioning.
• Tolila+Woods (formerly Tolila+Gilliland): French architecture practice with a strong track record in social housing, public facilities, and participatory housing projects in the Occitanie and broader French market. Directly comparable on client typology (HLM operators, municipalities) and project scale (€2–10M).

Broad incumbents

• AIA Life Designers: Major French architecture and engineering group with a substantial healthcare, education, and public-sector portfolio. Competes with Project 310 on larger municipal tenders but operates as a multi-disciplinary group with significantly greater resources.
• Architecture-Studio: Large established French architecture firm with significant public-sector, cultural, and urban planning practice. Competes against Project 310 in concours for major municipal projects but operates at much greater scale and geographic breadth.

Emerging players

• Encore Heureux: Paris-based architecture practice focused on circular construction, reuse of materials, and sustainable public architecture. Comparable niche positioning in environmentally committed public-sector design, with similar scale and specialisation.
