New Construction. 15 Zaccheus Mead Lane stands as a masterfully reimagined historic property, the original site of the c.1850 manor house of Zaccheus Mead Jr. 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. 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 premium Summer Rain irrigation system, custom architectural lighting, 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.
