Sag Harbor’s ‘Summer White House’ Back Up For Sale

The house where Chester A. Arthur, the 21st president of the United Sates, once lived in Sag Harbor.

Chester A. Arthur served as the 21st president of the United States from 1881 until 1885 — and, apparently, he summered in Sag Harbor.

At one time known as the “Summer White House,” the three-story, circa-1796 Victorian at 20 Union Street has once again hit the market, this time for $13.5 million with Rima Mardoyan Smyth and Ryan Struble of Douglas Elliman, and Susan Breitenbach from Corcoran.

Over the last three years, the 5,900-square-foot mansion on .34 acres underwent a complete renovation and redesign by architect Steven Gambrel, who brought the home into the 21stcentury while retaining its historic character, according to the listing. In August 2016, its owners set an asking price of $14.2 million before taking it off the market last November.

“The main floor includes a library with fireplace, formal dining and living room with stunning antique fireplace, kitchen and family room with fireplace overlooking the garden and pool,” the listing says. “The six bedrooms are spread out on the second and third floors offering beautiful views over the historic village of Sag Harbor.”
