It reflects suburban growth outward from Albany through Colonie. The formal English garden and landscaped grounds contribute substantially to its significance.","narrative":"Treemont Manor is a brick mansion built in 1929 at 71 Old Niskayuna Road in Colonie, Albany County. Designed by the New York firm Adams & Prentice and built by John B. Waldbillig, Inc., it follows the Georgian Revival style in the manner of an English Country house. The L-shaped house has a two-story servants' wing with a round-arched drive-through leading to a double courtyard. The main entrance sits on the second floor, reached by a brick stairway and framed by pilasters and a carved broken pediment. Inside are a curving three-story staircase, carved woodwork and Adamesque mantels. The eleven-acre estate keeps its original parcel, with woodland, open fields, hedges, exotic plantings, statuary and a formal English garden. A one-story guest house and a recent tennis court complete the grounds, though the tennis court does not contribute to the significance. The property was listed as a fine example of the large suburban estates that grew up around Albany in the early twentieth century.","period_of_significance":null,"architect_builder":"Architect: Adams & Prentice, New York City; Builder: John B.
