    What's special

    Great land
    A Rare Convergence of Beauty, Vision and Readiness in Greenwich's Golden Triangle. This property is for a discerning buyer who values time and predictability. This 2.3-acre parcel in mid-country Greenwich is a beautiful shovel-ready estate site. Custom architectural work by award-winning Saniee Architects. Full municipal approvals in place for a 10,000 square-foot residence -- eliminating a year or more typically spent navigating architectural development, design review, and the inherent uncertainty of the approval process. Privately set on one of Greenwich's most coveted addresses, the property offers complete architectural freedom -- no style restrictions, no compromises -- allowing a buyer to bring their own vision to life without delay. Top, prestigious location. Great land. Doesn't include the cost to build
