The Overview

A house, reimagined
for modern living.

Built in the early 1900s and reimagined over a two-year renovation, 140 West 88th Street keeps its original brownstone facade and proportions intact while adding a rooftop penthouse and a completely new three-story rear yard extension. Every part of the interior has been reconstructed to the highest building standards.

Five floors, a private garden, and a roof terrace with skyline views — this is a rare single-family offering on one of the Upper West Side's most coveted blocks.
