63 Flagg Court
ca. 1908, Ernest Flagg
New York City Individual Landmark

Located 100-feet northwest of the Gardener's Cottage, the Palm House was part of an area occupied by greenhouses which ran along the perimeter wall. Some of them were connected to it through a pipe system, which distributed the heat generated from large chimneys located at each end of the structure. It was originally a low one-story structure of fieldstone covered by a gable roof. The center section of the southwest slope was filled by a large skylight. The property was severely altered in 1987, when a two-story structure was added on the southwest side, thus changing the façade expression. It was included in the 1983 boundaries expansion of the 1967 NYC Landmark designation.
