What ALT 127 does

ALT 127 is a French architecture firm founded in 2014 by registered architects Olivier Delépine and François Bordier, operating from offices in Rennes (legal headquarters) and Dol-de-Bretagne (operational base). The firm provides comprehensive architectural design services across four primary categories: public equipment (aquatic centers, sports halls, fire stations, multi-function rooms, schools), healthcare and medico-social facilities (specialized care homes, medical-educational institutes, rehabilitation centers, medical centers), educational buildings, and tertiary projects (business hotels, central kitchens, municipal technical centers, offices). With a team of approximately 9 professionals covering conception, project management, all-trade supervision, and construction management, ALT 127 emphasizes bioclimatic design and HQE (Haute Qualité Environnementale) certification, producing buildings compliant with French environmental standards including RT 2012, RE2020, and BBC labels, frequently incorporating sustainable materials such as biosourced materials, wood structures, and photovoltaic installations. Documented completed projects range from a €420,000 waste-center extension to the €9.2M HT Centre Aquatique Dolibulle delivered in 2020.

The firm operates as a traditional professional services practice, generating revenue through architectural fees calculated as percentages of construction costs or fixed rates for specific missions. Its go-to-market relies primarily on participation in French public architectural competitions (concours) and direct commissions, with most projects acquired through public procurement procedures for municipalities, inter-municipal structures, regional governments, healthcare associations, and educational establishments across Brittany (Ille-et-Vilaine, Côtes-d'Armor, Morbihan) and adjacent western France departments (Maine-et-Loire, Loire-Atlantique, Manche), with one documented expansion into Île-de-France. Notable repeat clients include ADAPEI 35 across multiple healthcare and medico-social projects, alongside municipalities such as Dinan Agglomération, Ville de Nouvoitou, and Commune de Lanvallay. Marketing channels are limited to a portfolio website, competition participation, and professional network referrals.

ALT 127 is privately held by its two founding partners, with no external investment, no parent company, and no subsidiaries. The operational structure divides responsibilities between Delépine leading the Conception pole and Bordier leading the Chantier pole, with supporting project architects, an OPC supervisor, a construction manager, and administrative staff. The firm maintains working partnerships with specialist engineering consultancies (THALEM for fluids, SERTCO for structure, ECO+CONSTRUIRE for environmental consulting) on a project basis.
