Sonoma Valley, California’s Farmhouse Inn takes its name seriously. With a structure dating back to 1873, the hotel’s nine newly added guestrooms and spa add a sense of luxury to the building’s original identity.

“It was [my brother and my] lifelong dream to share our love of the Russian River Valley,” says co-owner and co-designer Catherine Bartolomei, who runs the inn with her brother Joe Bartolomei and partnered with San Francisco-based SB Architects for the guestrooms. The duo has owned the inn for 14 years, with Catherine living on the family ranch nearby. “The growing interest in Sonoma as a destination inspired us to further enhance the Farmhouse Inn experience,” she adds.

Designed to echo the historic hillside barns in the area, the new rooms also emulate the rustic aesthetic of the inn’s existing guestrooms, or Barn Rooms, but with added glamorous touches. Radiant-heated floors, indoor and outdoor fireplaces, and a jetted tub and steam shower give the rooms a modern feeling, while stone and exposed beams pair with and tongue and groove white washed walls and awnings for a barn house appeal. Equine images appear throughout the hotel in details such as printed pillows and other accessories.

“The main challenge was proportion and balance,” Bartolomei says. “We wanted it to not be too rustic, but evocative.” Stone fireplace surrounds contrast the marble tile and slab bathrooms, juxtaposing the natural with the luxurious. Reclaimed metal tiles and wood entryways also add to the appeal.

For the spa, the objective was to embody the feel of a “glammed-up horse stable,” Bartolomei explains. “The goal was to accomplish a sexy, equestrian feel.” Crafted by Healdsburg, California-based Myra Hoefer Design, the Spa at Farmhouse Inn features bold architectural accents, handwoven fabrics, and elegant furnishings.

A row of chairs made from reclaimed saddle blankets lines the main spa corridor, while a fresco of horses adorns the wood plank walls. “The aesthetic is old barns, stables, and beautiful old buildings on historic properties,” says Bartolomei. “The new spa is a natural extension of the Sonoma farm-inspired experience.” Vaulted, open beam ceilings, porcelain tile floors, and Dutch stable doors on the treatment rooms complete the picture.

“The idea was to create a feeling of old meets new, while incorporating a modern element in everything,” she adds.
