Bryan O’Sullivan Studio is a full-service international interior design studio with head offices in central London and New York City. The studio works with clients globally to create contemporary, liveable interiors informed by an elegant and eclectic European point of view. Projects span residential, hospitality, restaurants, bars, maritime and more. 


Interiors that are timeless yet truly original, sophisticated yet irreverent, and always welcoming are our hallmarks. High-quality natural materials and textiles are always a focus of the studio. Our aesthetic favours a simple, authentic glamour, realised through refined lines and inviting curvilinear shapes paired with custom contemporary furnishings and immaculate, considered antiques.


Every project is greeted with fresh eyes in order to create something truly unique for each client, including custom-made furniture and lighting that we create for every commission. For over a decade, Bryan O’Sullivan has been working with clients around the world while cultivating and nurturing global communities of creative collaborators and artisanal experts who contribute unparalleled craftspersonship to the studio’s interiors and furniture designs. 


Bryan brings an intuition to his work, balancing important historical references with an instinct for creating relaxed and inviting environments. While inspired by classical proportions of French and Italian architecture of the 1940s, 50s, and 60s, the studio's work is always innovating with new ideas that will endure over time.
