The story

  • Pool

A secluded drive winds to the top of the hill, arriving at Bella Vista de Valle—a Mediterranean estate that feels less like a traditional home and more like a high-end, private resort. This is a masterclass in effortless living, where 360-degree views of the valley and the majestic silhouette of Mount Diablo serve as the backdrop for a lifestyle centered around recreation and relaxation. Spanning over 13,400 square feet on a sprawling 5.31-acre lot, the estate is designed as a personal playground where every day feels like a getaway. Inside, the grand foyer’s 19-foot ceilings and stately columns lead you toward the heart of the house: a newly renovated gourmet kitchen. With dual Calcutta Supreme islands, designer chandeliers, and a "secret" hidden pantry, it’s a space built for hosting everything from post-game snacks to sophisticated soirées. The activity options here are truly in a league of their own. Rain or shine, the fun continues on the full-size indoor basketball court, in the billiard room, or within the dedicated exercise suite. For those who work as hard as they play, the richly detailed executive office offers a quiet retreat, while a private au pair suite ensures there is plenty of space for everyone. Step outside, and the grounds transform into a world-class recreational hub. You can sharpen your short game on the putting and chipping greens, start a match on the soccer field, or enjoy a sunset game of bocce. The spectacular pool and spa are the centerpiece of the outdoor experience, surrounded by multiple covered loggias, a full outdoor kitchen, and a fire pit perfect for starlit evenings. From the playground to the expansive terraces, every inch of this property is designed for active enjoyment. Bella Vista de Valle offers a rare combination of scale, sophistication, quality, and pure, unadulterated fun.
