Architect Roland Coate designed the English Tudor manor for Gertrude Young, the adopted daughter of hydroelectric power magnate William Kerckhoff, and her husband, Gerald. The architect was given a budget of $100,000 to build the 21-room mansion on North Hudson Avenue. It's now seeking $10.5 million. Cut stone, half timbering and mullioned windows reinforce the grand appearance of the home, built in 1929. An oriel window above the entry draws the eyes upward. Grounds of about an acre feature a tennis court and a formal English garden designed by noted landscape architect A.E. Hanson.
