Purdy's is a Gothic Revival-style house in Rothesay and is notable for both its creator and its later occupant. It was the first of many beautiful structures built by local master builder Joseph Henderson, who is credited with changing the architectural landscape of Rothesay around the beginning of the 20th century. On its own, Purdy's provides a good if small example of Gothic Revival residential architecture, featuring a steep gabled roof with thick bargeboards along the eaves and an open veranda.

In 1930, the house was acquired by local socialite and activist Dorothy Purdy. The house was nicknamed “Purdy’s” by her friends and has retained the moniker in her memory ever since. Purdy was an only child, raised by her widowed father, and she never married. She is notable for taking an active role during both World Wars and for being the first Provincial Secretary of the New Brunswick Girl Guides.
