From impeccably crafted furnishings to understated accessories, Jay Jeffers reveals how thoughtful layering and timeless materials create a space that feels both elevated and inviting.

Originally built in the late 1800s, The Madrona is a historic mansion that sits in the hills of Healdsburg, California, in the heart of Sonoma wine country. When tasked with updating the property’s interiors, Jay Jeffers turned to the aesthetic movement—which was flourishing at the time of the estate’s construction—for inspiration. “That period was all about living with beauty for beauty’s sake—surrounding yourself with things you love simply because they bring pleasure,” says the San Francisco–based designer.

Jeffers sought to honor the integrity of the architecture while elevating the functionality of the estate, where 24 suites and bungalows unfold across seven buildings. “One of the more meaningful restorations was bringing back a portion of the mansion’s original three-sided wraparound porch that had been removed at some point,” he says. “We also converted what had been a maintenance shed into a proper gym, and introduced a chef’s garden to support the restaurant.”
