About this home

300 Camille Avenue, known as the Ball Estate, is a gated Westside Alamo landmark offering unprecedented grounds, history, and timeless elegance. Set on approximately 3.98 flat acres, this legacy property captures the essence of refined luxury living. The residence spans over 8,800± sq ft across two levels, showcasing exquisite millwork, new appliances, formal and informal entertaining spaces, soaring ceilings, and lower level bonus room. The grounds are truly exceptional—anchored by majestic, mature redwoods that create a sense of privacy and serenity rarely found. Expansive, sun-drenched lawns stretch across the property, offering endless possibilities, including space for an ADU, while the natural canopy and thoughtful layout provide a peaceful, secluded retreat. In addition to the estate’s incredible privacy, it remains ideally positioned just a short distance from the Iron Horse Trail and surrounding hiking paths, seamlessly blending nature and convenience. Downtown Alamo and Danville are only minutes away, offering easy access to top-tier dining, boutique shopping, and everyday amenities. Designed for both grand entertaining and everyday living, the property also features a 1,579 sq ft pool house, an oversized resort-style pool, and a detached bar—creating a private, resort-like setting that feels worlds away, yet close to everything.
