Welcome to 9055 Summerhill Lane—a contemporary architectural estate by acclaimed Edmonds + Lee Architects, set on 40± gated and fully fenced acres in the heart of Sonoma’s Glen Ellen. Commanding 360-degree views of Sonoma Mountain and surrounding vineyards, this 4BD/4.5BA property offers 5,011± total sq ft of refined living—3,621± sq ft within the main residence—where steel floor-to-ceiling windows and doors dissolve the line between interior and landscape.

A dramatic great room anchors the home beneath a 30-foot cathedral ceiling, flowing into a gourmet kitchen outfitted with custom wood cabinetry, Bosch and Viking appliances, and a wood-and-steel frame staircase rising to the private primary suite wing. Stone and quartzite finishes, frame-less glass showers, floating backlit vanities, a custom translucent fireplace, and a fully integrated Sonos, Lutron, and security system bring a layer of quiet sophistication to every space.

Beyond the main house, a fully functioning guest house with its own kitchen and secondary primary suite, a dedicated fitness gym, a homework office, and an expansive pool and spa terrace finished in Ipe plank complete the compound. With manicured sport lawn and pasture, mature landscaping, well water, and standing opportunity for vineyard or equestrian amenities, this is Wine Country living designed for both legacy and everyday ease.
