O'Neil Langan Architects

What O'Neil Langan Architects does

O'Neil Langan Architects (OLA) is a privately held architecture and interior design firm founded in 1996 by partners Steven O'Neil and Mary Langan and headquartered at 118 West 22nd Street in Manhattan. The firm specializes in designing luxury and premium retail environments for global brands, with a documented portfolio spanning flagship stores, boutiques, and brand-immersive spaces across fashion (Tory Burch, Versace, Tommy Hilfiger, Burberry), intimate apparel and lingerie (Victoria's Secret, Savage X Fenty), athletic apparel (Lululemon), cosmetics (NARS, Bobbi Brown, MAC, Charlotte Tilbury/Hourglass), outerwear (Moose Knuckles), and emerging menswear (Bonobos). Service offerings are integrated end-to-end and include architectural services, interior design, project management, retail design, fixture design, image/identity design, visual merchandising, graphic design, and in-store promotion and packaging design. The firm has grown to over 50 employees.

OLA operates as a B2B professional services business with enterprise field sales motions, generating revenue through project-based fees set by scope and complexity. The firm assigns a dedicated triad — one Principal, one Associate, and one Senior Project Manager — to each brand client, liaising with brand leadership and real estate/procurement teams for new store rollouts, renovations, and global expansion programs. Despite operating from a single Manhattan office, OLA delivers projects across more than 23 global markets including New York, Los Angeles, London, Tokyo, Shanghai, Beijing, Rome, São Paulo, Auckland, and Toronto. The firm works with both established luxury houses and emerging/lower-budget brands scaling into new markets, and has no disclosed external investment, no technology platform, and no proprietary AI tooling.

The business competes primarily on creative reputation, named-principal relationships, and a multi-decade referenceable portfolio. Pricing is not publicly disclosed; go-to-market is relationship-driven rather than marketing-driven; and there is no public funding, M&A, or partnership activity disclosed in the available record.
