Tregaron Estate, originally called "The Causeway," is a 20.5-acre country estate in Cleveland Park built in 1912 for Alice and James Parmelee, who lived there until 1940. Architect Charles Adams Platt designed the mansion, with landscape architect Ellen Biddle Shipman laying out the grounds around it. From 1942 to 1958 the estate was home to former ambassador Joseph E. Davies and his wife, Post Cereal Company heiress Marjorie Merriweather Post.

The grounds. Beyond the mansion, the estate includes a carriage house, greenhouse, gardener's residence, and a Russian-style dacha added later by Ambassador and Mrs. Davies. Platt worked with the natural contours of the site, siting the mansion at the highest point of the grounds so it looks south over the city.

the style

The mansion follows a Georgian idiom, one thread in what the estate itself describes as a deliberately varied mix of architectural styles across its outbuildings, from the formal main house to the later Russian-style dacha.
