What QUARTUS Residential does

QUARTUS Résidentiel is a French real estate developer (promoteur immobilier) specializing in the construction and direct sale of new-build residential apartments and houses across France. The company operates as the residential development arm of the diversified Groupe Quartus and serves two primary customer segments through distinct go-to-market motions: primary residence buyers ("Habiter"), who purchase for personal use with personalization options, reduced notary fees (2-3% vs 7-8% for older properties), and RT 2012 energy-efficient standards; and buy-to-let investors ("Investir"), who access tax-advantaged products under the Pinel, LLI, and LMNP regimes, plus parking investments. The company also offers a premium selection channel, Quartus Privilèges.

The underlying technology and platform are conventional real estate development rather than a software product, but the company has invested in a digital sales and customer engagement infrastructure: a Microsoft Azure-hosted website, Inovia CRM, Actito email marketing, Pinpo SMS, Sérénis call-center pre-qualification, Avanci data enrichment, Power BI analytics, an online reservation client portal (Espace Client), and an apartment configurator tool. Sustainable construction is a stated technical differentiator, with proprietary use of biosourced materials (wood, straw, hemp) and a "Terre Crue" (raw earth) building technique tied to urban regeneration projects.

The revenue model is one-time property sales with unit pricing ranging from approximately €88,720 (entry-level studios such as in Belle Rive, Lormont) to over €1.4M (premium apartments such as Pavillon Raspail in Paris), with periodic promotional campaigns (e.g., "JOURS QUARTUS" offering €3,000-€5,000 per room). Geographic reach spans six French regions, supported by a hybrid direct-to-consumer sales model that combines online property search, physical showrooms (e.g., 143 bd Romain Rolland, 75014 Paris), and a customer referral program offering up to €2,500 per successful recommendation. Customer satisfaction is rated 4.6/5 based on 189+ Avis Vérifiés reviews.
