86 Sound Beach Ave Extension, Greenwich, Connecticut 06878

About this home

Located minutes from schools, parks, and shopping in the North Mianus school district, this home delivers on both location and livability. The open floor plan centers around a vaulted-ceiling living room, with hardwood flooring flowing throughout and a kitchen outfitted with brand-new stainless steel appliances. Three bedrooms plus a flexible office/nursery and a family room make for room to spread out. Outside, an oversized deck overlooking a lush, expansive yard is tailor-made for entertaining -- and with .35 acres, the potential for expansion is very real.
