Perched atop a dramatic ancient volcanic crag in the medieval village of Castiglioncello del Trinoro, Casa Bianca is the quintessential Tuscan countryside estate. The home also represents a significant milestone for Pacaso, a real estate marketplace for co-owned second homes, marking the company’s debut in rural Italy and bringing its co-ownership model to one of the most storied landscapes in the world.
Nestled in the pristine Val d’Orcia region of Tuscany — a UNESCO World Heritage landscape — Castiglioncello del Trinoro is not a destination most travelers find by chance. The village commands sweeping panoramas of the surrounding Tuscan landscape: hills and valleys, vineyards and fields of green and gold. It is a place defined by slowness, beauty, and an almost complete absence of the ordinary. Casa Bianca places co-owners inside the heart of the village, not just nearby.
“Tuscany has long represented a kind of ideal — a life lived more deliberately, in a place of extraordinary beauty,” said Austin Allison, CEO and co-founder of Pacaso. “With Casa Bianca, we’re bringing that vision within reach for owners who want more than a vacation. They want a home in Italy. A place that is genuinely theirs.”
The four-bedroom, four-bathroom residence spans approximately 2,400 square feet of stone-walled interiors shaped by centuries of Tuscan craft. Exposed wood beams, herringbone tile floors, arched doorways, and terracotta details speak to the home’s deep architectural roots, while a fully appointed chef’s kitchen, en suite bedrooms, and a private courtyard with open countryside vistas ensure modern comfort. A wine cellar completes the picture.
What distinguishes Casa Bianca from a typical countryside villa is the village itself.
The location is equally compelling beyond the village walls. Casa Bianca sits approximately two hours north of Rome and less than two hours south of Florence, within easy reach of Siena, Montalcino, and Montepulciano. The great hill towns, wine estates, and cultural sites that define the Tuscan imagination are all within a short drive.
Casa Bianca owners have access to the public amenities of a nearby boutique hotel just a short walk away — including a spa, pool, cooking classes, and acclaimed restaurant dining — all without leaving the hilltop. It is an unusual combination: the privacy and scale of a private home, set within a living community, with hotel-grade services available on foot.
