01The Residence
Thornhill is a 1928 Charles A. Platt commission, completely and quietly restored over six years by Ferguson & Shamamian. The 16,400-square-foot residence retains every important original detail — the limestone orangery, the cantilevered staircase, the linenfold-panelled library — while integrating a new wing for a generational family kitchen and informal great room. The grounds, originally laid out by the Olmsted Brothers, were re-interpreted in 2021: a long allée of clipped beech, two reflecting pools, a walled cutting garden, and a Har-Tru tennis court tucked behind a yew hedge. A carriage house, stables, and pool house round out a property that prefers privacy to spectacle.
