Cooper Kessel-Designed Mediterranean Style Estate in Springfield Estates Inspired by the villas of France and Italy, this estate blends architecture with sustainable design for a lifestyle of distinction. Inside, artisan details set the tone: cherry wood cabinetry, exposed beams, polished concrete floors with radiant heat, limestone and granite counters, and top-of-the-line kitchen appliances. The library offers a warm retreat with rich woodwork, while the office provides built-in functionality for working from home. The spacious primary suite includes a sitting room and French doors that open to the veranda. Two additional bedrooms—one an en-suite—welcome family or guests with comfort and privacy. Outdoors, the estate unfolds with manicured gardens, year-round blooms, raised garden beds, a greenhouse, and an orchard of fruit and olive trees. For the wine enthusiast, a temperature-controlled 1,000-bottle wine cellar awaits. Kessel’s design reflects both luxury and sustainability, featuring ICF construction, radiant heating, thermal cooling, and solar energy for efficiency without compromise. Just a couple of hours from the Bay Area, this is a perfect full-time residence or weekend retreat.
