Bryan O'Sullivan Studio is the eponymous interior design studio founded in 2013. The firm specialises in high-end residential, hospitality and maritime projects. The practice’s head office is in Shoreditch, London and now has an additional branch in New York. The studio is made up of a team of over 15 design specialists, including interior designers and furniture designers.

The firm designed a bar for west London hotel The Berkeley (pictured above), which features a pink-hued mural depicting female faces in an enclosed private area, making reference to snugs in old pubs where women could withdraw and socialise without judgement.
