HUGE PRIICE REDUCTION! Nestled within the prestigious rolling hills of Round Hill Country Club, this extraordinary residence sits on a sprawling 2+ acre parcel. A masterpiece conceived and executed by a renowned local architect for their own private sanctuary, this home transcends typical expectations. Every detail - 16-foot coffered ceilings in the great room to the bespoke Brazilian Cherry & Maple hardwood floors, speaks to an uncompromising commitment to quality. Walls of windows frame breathtaking 180+ degree panoramas of the Las Trampas Ridge Line and verdant valley below, creating an ever-changing living work of art. The chef’s kitchen, a culinary dream, boasts granite countertops, a new Sub-Zero refrigerator, Viking dishwasher, and a show-stopping six-foot cherry red La Cornue range imported from France. The main-level primary suite offers a private fireplace and a spa-like bath w/ freestanding soaking tub, oversized shower, and dual vanities. Each bedroom, including those on the lower level, features an ensuite bath and stunning views. Even the garage is graced with a vista. Complete with all copper gutters and downspouts, this is a home where no expense was spared, and architectural brilliance meets unparalleled natural beauty. Owned 10kw/H solar, 1,600 btl wine cellar
