William Cullum is the Senior Designer of Jayne Design Studio in New York City. A South Carolina native, William Cullum joined the Studio in 2011 after receiving his Bachelor of Arts from the College of Charleston in Art History and Historic Preservation. William’s deep interest and love of 18th and 19th century design deeply inspires his practice. His interiors are known for their imaginative use of texture, pattern and unconventional color. Through over a decade at the Studio, William has furthered the firms’ long-standing reputation of creating idiosyncratic interiors that are traditionally influenced and modern in execution.

William has furthered his design education by attending prestigious summer programs including the Victorian Society in America’s London Summer School, the Chicago Summer School, and most recently, The Attingham Summer School. In 2018, House Beautiful named him to their ‘Next Wave’ group of up-and-coming designers. In 2023, a project he worked on with architect Gil Schafer received a Palladio Award for its exemplary classical design. William’s home was recently featured in Elle Decor and his work has been featured by publications including Architectural Digest, Veranda, The Wall Street Journal and The New York Times, amongst others.

Recently he worked on the restoration and decoration of the historic Branford-Horry House residence in Charleston, SC for a young family. A few other special projects in the works include a private residence in the Carlyle Hotel, a Victorian house on Oyster Bay and a Neoclassical country house in Connecticut – both with Peter Pennoyer Architects.
