Old-school mid-century glamour with a contemporary touch is the hallmark of interior designer Bryan O’Sullivan’s repertoire, on full display in his commissions for the Red Room at the Connaught Hotel, the much-admired Berkeley Bar & Terrace, and the art deco Painter’s Room at Claridges, all some of London’s most fabulous and plush spaces. With expertise in both architecture and interiors, O’Sullivan’s broader vision is reflected as well in selected residential projects, which range from a family home in Bel Air to a mansion in Notting Hill, a historic early 1900s hôtel particulier in Paris’s 16th arrondissement and a 69.5 meter yacht.
