Suzanne Tucker’s clients wanted to update the kitchen of their weekend cottage in Napa Valley, which they’d owned for more than 30 years. It was a relatively small job for Tucker, an experienced designer who’s usually tasked with transforming entire residences. Yet the clients were longtime friends, and so the kitchen renovation began. It didn’t take very long for new ideas to arise. Tucker soon found herself redecorating the living room, then the library, followed by a bedroom, a bathroom, and eventually the pool pavilion and all of the home’s outdoor terraces, which overlook a picturesque garden filled with rose bushes, climbing vines, and intricately pruned boxwoods. “There was a domino effect,” says the designer, whose firm, Tucker & Marks Inc., has been in business since 1986. “It became one of those wonderful projects that had a lovely lifespan.”
