Designed by San Francisco-based Klopf Architecture, this residence is a striking Sonoma mid-century remodel, reimagining a classic 1960s home nestled into a hillside in Sonoma Valley. Spanning 4,068 square feet, the flat-roofed structure blends subtly into the boulder-strewn slope, while its low profile and linear form maximise panoramic valley views.

The home’s exterior features warm stained cedar cladding, enhancing its integration with the surrounding landscape. The front elevation is private and understated, punctuated by minimal windows and anchored by a bold glass entry door. To the rear, the house opens dramatically with retractable glazing, connecting the interior to a spacious patio and infinity pool overlooking Sonoma Valley.

Inside, the mid-century modern remodel follows a smartly zoned layout. A central foyer separates private and public spaces. To the west, three bedroom suites offer tranquil retreats, each with seating areas and private baths. The eastern wing houses an office, gym, and a seamless open-plan kitchen, dining, and living space. A continuous glass wall in the living area extends views across the pool and deck, drawing in the surrounding landscape.

This hillside mid-century renovation ensures nearly every room connects to the outdoors, thanks to the home’s elongated footprint. Deep overhangs provide shade from Sonoma’s intense sunlight, while custom rain chains elegantly guide rainwater to drains, replacing conventional downspouts.

Interior materials were chosen to reflect the warmth and clarity of modern California design. White oak floors and cabinetry, post-and-beam ceilings, and Calacatta marble bathrooms create a calm, refined atmosphere. Together, these elements preserve the home’s mid-century essence while introducing the elegance and efficiency of contemporary architecture.
