“I surrounded the mirror with botanical prints to emphasize the ceiling height,” Samperton says. A Restoration Hardware sleeper sofa is covered in an indoor/outdoor fabric from Perennials; the coffee table easily moves for sleepovers. “There’s nothing too serious or precious here,” she says — her dog, Tricky, is welcome in every room. “It’s all about kicking off your flip-flops and relaxing.”

Samperton personalized the apartment with artwork by family members, including this oil painting by her boyfriend’s stepmother. The frame’s cutouts complement the vintage dining chair designed by John Van Koert for Drexel. “Furniture you can see through makes a small space feel larger,” she says.

An Anglo-Indian campaign chest contrasts with a round CB2 mirror.

To save space in the bedroom, the designer hung a vintage rug in place of a bulkier headboard. The striped pillows are from Heather Taylor Home. 

“We walk in with sand on our feet, so flatweaves are great,” Samperton says of the bedroom’s layered rugs. “You don’t see any stains, and you can sweep them.” To camouflage an awkward corner, she added a tropical touch with a rope chair from Hangloose Hammock Company. “It’s an ideal place to read or take a nap,” the designer says.

Samperton’s vibrant beach wardrobe is housed in a 19th-century English armoire. 

Samperton’s debut collection of linen fabrics is available through Hollywood at Home in Los Angeles.
