LE SQUARE

What LE SQUARE does

LE SQUARE is a Paris-based showroom, exhibition, and expert center dedicated to building envelope solutions, including windows, facades, glazing, solar protection, coatings, and security systems. Founded in 2022 as a wholly-owned initiative of the Reynaers Group and co-established by its brands Reynaers Aluminium and Forster, the company operates a single 400m² loft showroom at 46 rue Chanzy in the 11th arrondissement of Paris. The space was designed by Studio 5.5 with a circular-economy aesthetic, featuring durable materials and furniture fabricated from aluminum and steel offcuts, and is organized into a discovery zone for partner systems, a 'Blue Lab' project development workshop, and an industrial-styled relaxation area. LE SQUARE does not sell products directly; instead, it curates and presents solutions from 15+ specialized industrial partners, including Reynaers Aluminium, Forster, AGC Glass Europe, Vetrotech (Saint-Gobain), Serge Ferrari, Bandalux, Axalta, Dormakaba, effeff France, Reckli, and Immoblade, across fenestration, technical glazing, solar protection, coatings, security, and concrete facade categories.

The company serves architects and engineering offices (Bureaux d'études) seeking to discover, compare, and specify high-performance building envelope systems for new construction and renovation projects. Visits are conducted by appointment only, with personalized accompaniment from specialized experts from the partner brands. LE SQUARE also functions as a professional networking hub and training center, hosting masterclasses, expert-led sessions, and industry events, and benefits from media partnership with the French trade magazine Verre et Protections and trade press visibility across publications including Batinfo, V&M, Archilive, MétalFlash, and Echo de la Baie.

The business model is B2B professional services and advisory rather than transactional. LE SQUARE is legally structured as a Société Anonyme (LE SQUARE – REYNAERS ALUMINIUM, SA) with a share capital of €7,000,000, and operates without external venture capital, private equity, or public listing. The parent Reynaers Group provides financial and strategic backing, while Philippe Juliard serves as Director of Publication. The core value proposition is the consolidation of fragmented specialist manufacturers into a single curated physical environment that simplifies the specification process for design professionals and reinforces the market presence of the Reynaers Group's portfolio of brands in France.

Revenue is derived from the facilitation of project conception, expert consultation, and connecting visitors with partner manufacturers. The model is service-oriented and B2B, focused on inspiring and accompanying architectural design rather than direct product sales.
