What atelier asa-i does
Atelier Asa-i is a French interior architecture firm structured as a SARL (Société à Responsabilité Limitée) with share capital of €3,000, founded and led by Alexandrine Santafé, a certified Architecte d'intérieur CFAI (N° 1469). The firm is headquartered operationally in Bures-Sur-Yvette, Essonne, with its registered siège social in Etampes, and is registered with RCS Evry under SIRET 815 407 051 00011 and APE code 7410Z (architectural activities). It delivers full-cycle interior architecture and maître d'oeuvre (project management) services spanning feasibility studies, concept design (APS/APD), tender documentation (DCE), construction supervision (DET), and final reception (RDT), using CAD documentation and 3D modeling/rendering tools for client visualization.
The firm serves a diversified client base across six primary segments: individual residential clients (apartments, houses, farmhouses, lofts) as the core market; retail and hospitality operators (restaurants, bars, boutiques, showrooms); healthcare practitioners (medical cabinets, physiotherapy practices, multi-cabinet health centers); office and tertiary-sector companies; real estate agencies and VEFA developers requiring pre-sale staging plans; and prestige-property owners (including multi-phase château renovations). Notable engagements include 3D modeling work for AXA at La Défense, an office renovation for UX Republic in Paris 11e, a crêperie fit-out for La Boucane in Aulnay-sous-Bois, multi-cabinet medical conversions in Etampes, and a Bonnelles château multi-phase prestige renovation. Coverage extends across the Île-de-France region (Essonne 91, Paris 75, Yvelines 78, Hauts-de-Seine 92, Seine-Saint-Denis 93, Val-de-Marne 94).
Commercially, Atelier Asa-i operates as a sales-led professional services boutique with no external funding, no parent company, and founder-owned equity. It acquires clients through a website portfolio, multi-platform social presence (Instagram, Facebook, Pinterest, LinkedIn, Houzz Pro), and earned media in Elle Décoration (2018), A Vivre (2018), and Ma Vallée (2020). Pricing follows standard French architect conventions: percentage-based fees calculated on the hors-taxes works budget (with provisional installments and end-of-project reconciliation) or fixed/forfait fees where scope is defined upfront, with surcharges for phased work and indemnities on early termination. The firm supplements capacity via co-development partnerships (LLOA Architecture for structural surélévations, AK DESIGN for office fit-outs) and a channel-partner program with real estate agencies for VEFA staging, allowing scope expansion beyond a solo-architect delivery model.
