What's special

Pool houseClassic bordeaux varietalsRefined modern craftsman aesthetic

Knight's Valley's premier vineyard estate is now ready to welcome its next steward. Set atop a scenic knoll, this exceptional 20 acre property features a thoughtfully composed compound including a main residence, pool house, a historic 1880's carriage house from the estate's earliest days, and a distinctive barn residence designed by William Turnbull. Nearly $3 million in recent enhancements have infused the property with a refined modern craftsman aesthetic, blending timeless character with contemporary comfort. Approximately ten acres of hillside vineyards, planted with classic Bordeaux varietals, trace the natural contours of the land. From every vantage point, sweeping panoramic views unfold across rolling vineyards, rugged mountains and the valley floor below.
