House of Cerruti | Biella, Piedmont, Italy

The spirit of the late Nino Cerruti, famed Italian designer and textile entrepreneur, endures in his historic home in the heart of Biella, Piedmont, a world-famous destination for its textile and wool industry and the real Made in Italy movement of Italian fashion. Never before offered for sale, the House of Cerruti is scheduled to auction with a €1.25 million Reserve next month via Sotheby’s Concierge Auctions in cooperation with Italy Sotheby’s International Realty.

“My grandfather was not just a fashion designer, he was a visionary,” stated Ian Cerruti, current homeowner. “His unique blend of Italian elegance and French style—along with his keen eye for detail, impeccable taste, and unwavering dedication to quality—is an essence that is not only captured in his designs, but in this home as well. As a piece of not only Cerruti history, but Italian history itself, we hope to see this environment inspire and influence its next owner for years to come."

The estate is ideal for large family gatherings or hosting friends. Enjoy the breathtaking views of expansive peaks in the distance from the multiple terraces. With on-property wine production capability, a quality glass of vino is always at hand.
