Henry Davis Sleeper, an antiquarian, collector and interior decorator, began it in 1907 with plans by local architect Halfdan M. Hanson, then enlarged it repeatedly until his death in 1934. The result is an irregular house of brick, fieldstone and shingle with towers, bays, porches and a maze of roof forms, grown to fifty-six rooms. Inside, Sleeper arranged themed and period rooms using architectural salvage from Colonial houses, along with furniture, glass, ceramics and other collections. Examples include the Pine Kitchen with woodwork from a c. 1650 house in Pembroke and the red-accented Octagon Room. A gatehouse, tool shed and garage built by Sleeper also survive. Later owners preserved the house and collections, and in 1942 it passed to the Society for the Preservation of New England Antiquities. It now operates as a seasonal museum, with its design and contents largely intact.","period_of_significance":null,"architect_builder":"Halfdan M.
