A Landmark 100-Acre Estate Set in Prestigious Alamo | The only 100-acre estate in the East Bay, 10 Serenity Lane offers unmatched privacy, scale and distinction. Inspired by classic European architecture, the residence pairs quiet sophistication with remarkable potential. A gated, Crepe-Myrtle-lined drive leads to sweeping natural vistas, manicured gardens and thoughtfully designed outdoor spaces. Inside, expansive rooms support refined living and elevated entertaining, with multiple viewpoints capturing the surrounding hillsides. Signature amenities elevate the experience, including a 20-car showcase car barn, an inviting club room and a temperature-controlled wine cellar—ideal for collectors and connoisseurs. Outdoors, the grounds reveal vineyard elements, flourishing gardens and a res ort-style pool and cabana that enhance the property’s retreat-like atmosphere. This is a rare opportunity to secure the East Bay’s premier legacy estate before its planned renovation, offering significant upside in one of the region’s most coveted luxury enclaves.
