A1 ARCHITECTURE

What A1 ARCHITECTURE does

A1 Architecture is a France-based boutique architecture firm operating as a SASU, founded by Stéphane Elasri, who brings over 35 years of experience since 1980. The firm delivers bespoke architectural design across six product categories: luxury villas and residences, collective housing, hotels and tourism, senior residences (EHPAD), commercial spaces, and interior architecture with custom furniture design. Projects span conception through construction supervision and integrate environmental, administrative, and aesthetic constraints into a client-centered process.

The company's business model is professional services, generating revenue through project-based fees for design, permitting, execution plans, and construction oversight. GTM is sales-led via direct consultation with individual homeowners (particuliers) and property developers (promoteurs), supported by a website portfolio, city-specific SEO landing pages, and Google Business reviews. The firm operates primarily in Île-de-France with regional execution in PACA and select international projects (notably the Louxor Hotel Complex in Egypt and Marejada's Resort in the Dominican Republic).

The company is small (8 employees), founder-controlled with Stéphane Elasri as sole shareholder and President, and headquartered on a barge at 37 B Quai Jean-Baptiste Clément, Alfortville. It holds GDPR compliance certification, has no external institutional funding, no subsidiaries, and no disclosed revenue. The competitive positioning rests on the founder's design talent, a multi-decade project portfolio (including a 50,000 m² hotel competition win), and breadth across residential, commercial, hospitality, and senior-living typologies.
