What Maison Numéro 20 does
Maison Numéro 20 is a Paris-based interior architecture and design studio founded in 2013 by Oscar Lucien Ono, specializing in bespoke luxury interiors for the hospitality sector and high-end residential clients. The studio delivers end-to-end design from furniture and seating to lighting, custom rugs, and one-off creations, all produced in collaboration with a curated network of artisans. Notable clients include Hyatt Regency, Sofitel, Pullman, Accor (Mercure Tour Eiffel, Tribe), Relais & Châteaux, Buddha Bar, Chloé, Fauchon, Dalloyau, Le Paradis Latin, Roland Garros, and Barnes Immobilier, spanning hotels, restaurants, luxury fashion houses, sports venues, and real estate firms.
The studio's core technology is its bespoke design approach combined with artisan-sourced manufacturing: every piece is designed to enhance the space with timelessness, elegance, originality, and excellence, with customizability and configurability as the primary differentiator. The portfolio emphasizes a "discreet, refined, and harmonious sense of luxury" and the firm has been recognized with multiple industry awards (Talents du luxe et de la création 2019, Best Hospitality Concept 2022, Best Hospitality Interior Project 2023, Hotel & Lodge Awards ranking 2023, FD100 Le French Design 2024) and editorial coverage across AD Italia, Wallpaper*, Architectural Digest, Elle Décoration, Bazaar, and Marie Claire Maison.
Maison Numéro 20 operates a professional services business model with project-based design fees and bespoke furniture/element commissions, selling primarily through direct enterprise relationships. The go-to-market is relationship-based enterprise field sales into luxury hospitality groups and high-net-worth private clients, with a secondary segment in luxury brands and retail environments. The firm maintains a headquarters at 26 rue Jacob in the 6th arrondissement of Paris and an additional office in Madrid (Calle Costa Rica 13), with project deliveries spanning France, Germany, Spain, Italy, the UK, the USA, the Netherlands, Morocco, Hungary, Portugal, China, and the Caribbean (Saint-Barthélemy). Ownership is private and founder-led, with no disclosed external investors, funding rounds, or parent company.
