Winner of the 2022 LUCY G. MOSES PRESERVATION Award

THE JOHN DWIGHT HOUSE - PAST IS PROLOGUE 

NOW REDUCED BY NEARLY $1,000,000

Following the lead of McKim, Mead & White, this house was built in 1890 in the neo-Renaissance Revival style by architect Frank Hill Smith for John Dwight. It was erected during The Gilded Age (from 1875 to 1900 or 1910), and financed by his baking soda empire, Arm and Hammer. This product dominated the market from 1873 onward and is still popular today. Frank Hill Smith was also a painter who collaborated with William Morris Hunt in the 1880s, which may account for his preoccupation with interior design and color, which is reflected in the house we see today.

AWARD WINNING HISTORIC RENOVATION

During their decade long ownership, the present owners engaged the illustrious architect, Samuel G. White, the great grandson of Stanford White, to restore the interior design elements and original floor plan of this house. The mission of White's varied architectural practice is defined as "combining historic restoration and adaptive reuse with new designs and historic settings" and this house offered the perfect palette. Among many other projects, White has modernized Stanford White's Astor Court in Rhinebeck with a similar philosophy. Astor Court was built originally built for John Jacob Astor IV and inspired by The Grand Trianon at Versailles.

CORNER HOUSE WITH EXCEPTIONAL LIGHT

As New York townhouses tend to be adjacent to each other facing north and south, finding a corner house with light on three sides is extremely rare.

This house faces west, south and east, with sets of huge square windows and an amazing five corner rooms. The numerous windows on the long side of the house infuse the interior with an exceptional amount of light. Further adding to the abundant light are four oval rooms on the long side of the building also with huge sets of windows.

In total, the house possesses 52 large windows, an extraordinary number. Few houses are so blessed with this amount of natural light.
