New Construction. Perched on a hill within Greenwich's prestigious Rock Ridge neighborhood, this 7,400 sq. ft. residence underwent a complete architectural top to bottom reconstruction in 2026 by The Franco Group and Dodaro Architects. Once the site of Zaccheus Mead Jr.'s home, the property seamlessly pairs its historic lineage with beautiful design and top-of-the-line mechanical systems just minutes from Greenwich Avenue.
Striking shingle roof accented by custom copper gutters, extensive stonework, a massive stone chimney, and an elegant stone-arched port-cochere. Professionally designed grounds by GroPro featuring a pool with water features, an outdoor kitchen, a separate hidden patio with firepit and beautiful gardens. There is also a generator. The grand foyer features a striking glass, oak, and brass staircase, 12-foot oak-beamed ceilings, and diamond-pattern marble flooring. The great room highlights custom-paneled 9-foot ceilings, oak feature walls, a contemporary limestone fireplace with a honed stone floating hearth, an integrated Frame TV, and custom 11-foot credenza and bar with custom brass inlay, stone tops and overhead brass and glass shelving. The Epicurean Kitchen features a custom chef's space equipped with a massive center island, top-tier appliances, dual dishwashers, a microwave drawer, a walk-in pantry, and an adjacent oak-paneled sunlit breakfast room overlooking the pool and gardens. A high-gloss lacquered custom library, a powder room with a carved marble sink, a sun-drenched sunroom, a mudroom, and access to the three-stop elevator.
The home has 6 ensuite bedrooms. The primary suite sanctuary includes a vaulted coffered ceiling, a private patio, dual California Closets, and a Zen-inspired bathroom complete with radiant heated floors and a deep soaking tub and matching vessel sinks. Also on the upper level are three additional ensuite bedrooms, including two with views of the grounds and access to a large Ipe roof deck. A separate guest/versatile suite is located above the garage featuring its own coffee bar and a large multi-purpose room. There also is a lower-level ensuite bedroom ideal for family, guests or staff.
The lower-level, an entertainment & wellness haven with an expansive walk-out footprint with full-sized windows and airy 8.5-foot ceilings. The wellness center is a state-of-the-art home gym equipped with a custom 5-person sauna and a cold plunge soaking tub. A large media room with a giant TV and full surround sound, a billiard area featuring a custom, temperature-controlled wine wall, a dedicated wet bar, and a full bathroom serving both the lower level and pool area.
