About 528 Round Hill Road

Stunning New Construction. A Grand Estate of Architectural Distinction. This Incredible new build was Conceived and Constructed without Compromise. A build of enduring significance beautifully set on 4 acres. Spanning 17,197 square feet, this residence achieves extraordinary vertical volume with 11-foot ceilings on the main level and a breathtaking two-and-a-half-story family room framed by floor-to-ceiling glass. The main level features a Chef's kitchen with an oversized 14-foot island, a glass-enclosed wine room, a stately library and a first floor guest suite. Upstairs, the private primary wing offers a dramatic atrium, vaulted ceilings, and "boutique" level his-and-hers closets. The walk-out lower level with 11 foot ceilings serves as a private resort-level retreat, featuring a glass-enclosed fitness center, a serene octagonal meditation room, and a state-of-the-art golf simulator. Outside, a 3,200-square-foot multi-level masonry terrace leads to a resort-style pool and a fully appointed pool house with a wood-burning fireplace. This estate features a black slate roof, Marvin high-performance windows, and intelligent luxury systems including a Lutron smart lighting system, a 38KW standby generator, and electric vehicle charging. This purpose built masterpiece is designed to stand apart in one of Greenwich's most prestigious settings. Completion expected spring of 2027.
