The Langdon Estate Gatehouse is a historic home located in Hyde Park, New York.

It has a rectangular main block with a kitchen wing covered by steeply pitched, slate-covered, hipped roofs with round-head dormers.

Walter Langdon built the gatehouse as a wedding gift for Emily Astor Kane, his favorite niece.

"[2] As part of Vanderbilt's extensive redesign of the grounds, he commissioned the construction of a new stone gatehouse.

They applied a "built-by-hand" approach to the project - restoring even the smallest of details inside and outside the home.
