What RDAI does

RDAI is a privately held Paris-based architecture studio founded in 1972 by Rena Dumas (originally as Rena Dumas Architecture Intérieure), specializing in architecture, interior architecture, and design across all scales — from buildings and flagship retail spaces to individual objects and furniture pieces. The firm operates as a French société par actions simplifiée (SAS), with wholly owned subsidiaries RDAI-Architecture (est. 2007) and RDAI Architecture Asia (est. 2020/2021 in Hong Kong), and is governed under artistic direction by Denis Montel (since 1999) and CEO Julia Capp (since 2022). It serves enterprise clients primarily in luxury retail (most notably Hermès, a continuous relationship since 1976), luxury hospitality (e.g., SO/ Paris, Les Bains Paris, Hyatt Regency Taghazout, Louis XIII), high-end residential, workplace (Capgemini), and cultural institutions (RMNGP Musée du Louvre, Cité des Métiers Hermès Pantin).

The firm's core offering is professional design services delivered through a transdisciplinary methodology that combines architecture, landscape architecture, scenography, and strategic design. Two internal platforms distinguish RDAI from a conventional architecture practice: the Matériauthèque (Materials Library), an internal department established in 2000 that maintains relationships with approximately 5,000 international material suppliers, and a dedicated Research & Development department that develops forward-looking design solutions. The firm executes approximately 70 international projects annually across 35+ countries, supported by a 100+ employee bench from 10 nationalities.

RDAI's revenue model is fee-for-service project engagement with enterprise clients, sourced through direct relationships, referrals, and industry recognition rather than traditional marketing channels. Pricing is not publicly disclosed and is negotiated per project. The firm invests in brand prestige through consistent participation in design weeks (Maison & Objet, Paris Design Week, Art Basel, Salone del Mobile), industry awards (Prix Versailles, AHEAD, Equerre d'Argent, AD100), and leadership visibility at international conferences. Distribution is direct — no intermediaries or channel partners — and the firm opened its first international branch in Hong Kong in 2020/2021 to support its Asian pipeline.

Broad incumbents

• Gensler: Gensler is the largest global architecture and design firm, with thousands of employees and projects across retail, hospitality, and workplace.

• Kohn Pedersen Fox: Kohn Pedersen Fox (KPF) is a global architecture firm headquartered in New York with expertise in commercial, mixed-use, and luxury-grade buildings. Its scale and global delivery capability make it a broad incumbent that competes for the larger architecture mandates RDAI may increasingly encounter.
• Foster + Partners: Foster + Partners is a global architecture firm with a strong track record in luxury retail flagship commissions (e.g., Apple, Hermès Maison Ginza alongside RDAI). It is a broad incumbent with overlapping capabilities in luxury retail and cultural architecture.

Its emphasis on materials, craftsmanship, and bespoke objects parallels RDAI's Materials Library-driven approach, making it a relevant peer for premium interior work.
• Pierre-Yves Rochon: Pierre-Yves Rochon is a French interior architecture studio recognized for luxury hotel design for brands such as Four Seasons, Mandarin Oriental, and Peninsula. RDAI's hotel and heritage work (e.g., Les Bains Paris, SO/ Paris) aligns closely with Pierre-Yves Rochon's positioning in luxury hospitality interiors.
• Peter Marino Architect: Peter Marino Architect is a New York-based architecture studio specializing in luxury retail flagship design for brands like Chanel, Dior, Louis Vuitton, and Bulgari.
