The Derby Summer House sits on the Glen Magna Farms property in Danvers, Massachusetts, and is a rare and excellent example of a formal 18th century garden house in the Federal Style. The structure was built in 1793-94 by Samuel Mclntire, the noted craftsman-carpenter of Salem, on the country farm of Elias Hasket Derby in South Danvers. The Derby Farm was sold off by the family, but in 1901, Mrs. Ellen Peabody Endicott, a descendant of the original owners, bought the Derby Summer House and transported it to Glen Magna Farm, their own summer residence. A shopping center now occupies the original location of the Derby Farm. Inside the structure on the first floor, there are two small rooms which are divided by a central hall that extends through the structure. The steps and vestibule at this level are surfaced in white marble. The second floor, where tea was served, was decorated in an Oriental manner. A wood parquet floor, dating from the first decade of this century is still in place. The structure with its carved figures has been studied and replicated by architects and historians for decades, but nothing beats the original.
