Restored in the early 20th century by Norman Isham, it is now maintained by the East Lyme Historical Society as a museum.

It is a 2+1⁄2-story structure, with a post-and-beam timber frame erected on six 2-story wall posts, and covered by a steeply pitched roof with a large brick central chimney.

The entrance is in the central bay, with flanking pilasters rising to a transom window and corniced entablature.

A small, stone-walled partial cellar pit under part of the hall was reached through a trap door.

The house was given a painstaking restoration to its believed 17th-century appearance under the guidance of early preservationist Norman Isham, and was opened as a museum in 1915.
