Golden Square

What Golden Square does

Carré d'Or is a privately held French real estate developer founded in 1998 and headquartered at 51 avenue Sidoine Apollinaire in Lyon's 9th arrondissement. The company constructs, sells, and leases newly built residential and tertiary (commercial/office) properties, with a stated emphasis on environmental, ethical, and societal sustainability integrated at every stage of project development. Under President Alain Dutoit and Managing Partner Nicolas Barbosa, the firm operates as a reference player in the Lyon new-build market with active programs including AUGUSTE (a 26-unit T2-T5 duplex residential development in Lyon 69007 organized around a landscaped island) and CONVERGENCE (a residential program in Tarare 69170), alongside a portfolio of ten or more completed realizations across the Auvergne-Rhône-Alpes region (including Lyon, Tarare, Limonest, Dardilly, Corbas, and Saint-Gervais-les-Bains).

The underlying technology is traditional real estate development with a sustainability methodology rather than a proprietary software or platform architecture; the company has no disclosed patents, certifications, or technology stack. Carré d'Or markets and sells directly to consumers and commercial tenants through its own website (carredor.immo) and an in-house sales team reachable via a single Lyon phone line, with programs pre-commercialized before construction. The revenue model is one-time transactional: proceeds come from the sale of individual newly built units (T2 through T5 duplex) and tertiary spaces, with no recurring subscription or rental revenue disclosed beyond what's implied by the leases mentioned in the firmographic description. There is no public pricing, no investor disclosure, and no external capital structure; ownership appears management-led with 11-50 employees.

The firm targets three customer segments: (1) primary residential buyers (individuals and families seeking sustainable new housing in metropolitan Lyon), (2) tertiary/commercial clients (businesses acquiring or leasing workspaces), and (3) property investors (interested in sustainable new-build assets). Pricing is not publicly listed; prospective buyers contact the sales team directly. The go-to-market motion is direct-to-consumer with no intermediary brokers, supported by a partnership with Lyon web agency Studio HB for digital presence. Value proposition centers on landscape-integrated, environmentally conscious construction and a builder identity articulated by Dutoit as building "larger than ourselves" rather than delivering commoditized square meters.
