Architecture studio Sylvain Guittet

What Architecture studio Sylvain Guittet does

Atelier d'Architecture Sylvain Guittet (AASG) is a French architecture studio operating as a single-member EURL (Entreprise Unipersonnelle \u00e0 Responsabilit\u00e9 Limit\u00e9e) headquartered at 9 Rue Th\u00e9r\u00e8se, Bagnolet (Seine-Saint-Denis, Greater Paris). Founded and led by g\u00e9rant Sylvain Guittet, the firm employs approximately five people and delivers a full architecture service offering across residential (collective housing, individual homes, senior residences, mixed-use developments), commercial (offices, retail, hospitality), public/educational facilities (childcare, schools, recreational centers), urban planning, and historic-building rehabilitation. The studio's core technology is its design expertise itself: no proprietary software, API, or AI tooling is disclosed, and revenue is generated through standard French architectural mission types (Faisabilit\u00e9, Esquisse, Concours, APS, PC, DCE, MOEX, and complete missions) billed per project under multi-year contracts. Notable mandates include the \u20ac11.7M HT rehabilitation of the Th\u00e9\u00e2tre National de l'Op\u00e9ra Comique with OPPIC, the 195-unit Drancy housing development for Vinci Immobilier and Nexity, the BOMA Suresnes office rehabilitation (20,000 m\u00b2) with Generali Real Estate yielding HQE, BBC and BREEAM Very Good certifications, the Diapason Franconville (144 units + cr\u00e8che) for Vinci Immobilier, and the Le Printemps Haussmann boutique renovation.

The go-to-market model is enterprise/field-led project acquisition through French public architecture competitions, direct commissions from real-estate developers and government bodies, and long-term trust-based relationships with public-sector owners (ma\u00eetrise d'ouvrage). The firm structurally preserves optionality on each mandate via the EURL status, allowing association with handpicked external partners sharing its working philosophy. Strategic alliances include Pierre-Antoine Gatier (Architecte en Chef des Monuments Historiques) for heritage work, Jacques Garcia for premium private interiors, Saguez Workstyle for workplace design, Les Crayons for scenography, and Anthony B\u00e9chu Beijing for Chinese competition work. Geographic footprint is concentrated in \u00cele-de-France, with historical international projects across China, Morocco, South Sudan, Sudan, Guinea, and Italy, most anchored on competition wins with UNOPS and other governmental bodies. The company is founder-owned, bootstrapped, with no institutional investment, no disclosed revenue, and no public listing; operating status is active with website content updated through 2024\u20132026.
