What Studio Castille does
Studio Castille is a Paris-based interior architecture and renovation agency founded in 2017 by three co-founders — France Lepoutre, Coline de Rivoyre, and Mathilde Abeel. The firm provides comprehensive interior design and renovation services for residential and commercial clients, with stated specialization in preserving architectural heritage (Haussmannian apartments, 1920s–1930s properties) while integrating contemporary custom-designed elements. It operates from offices in Paris (4 rue de Compiègne) and Lyon (9 rue du Doyenné), with a planned third location in Marseille, and delivers approximately 80 to 100 projects per year across both private individuals and professional clients.
The service offering follows a four-phase methodology — feasibility study and budget definition, design conception, construction site monitoring, and final reception — with each project managed by a single interlocutor. The firm acts as main contractor on turnkey renovation projects, coordinating a vetted network of local artisans, general contractors, engineering firms, and thermal specialists. Revenue is generated through professional service fees for full-service interior architecture engagements and project-level turnkey renovations, with pricing customized per project based on scope, surface area, and complexity. Customer acquisition is direct and sales-led, driven by a content marketing strategy (blog, Instagram, LinkedIn, Houzz, Pinterest) and earned media coverage in French design publications.
Studio Castille is structured as a private SAS (Société par Actions Simplifiée) with €1,500 in share capital, registered in Paris under SIREN 823567540. The company is founder-owned with no external investment, private equity involvement, or parent entity, consistent with its boutique scale (1–10 employees). The firm's proprietary methodology emphasizes eco-responsible material selection (certified, bio-sourced, and recycled materials), a curated material library, and expertise in heritage property restoration. Its primary commercial segments are private residential clients (mid-market homeowners and property investors) and professional commercial clients (retailers, restaurateurs, offices), each treated as a primary business unit with overlapping project teams.
