Built in 1813 and enlarged by about 1850, it is a distinctive local example of Greek Revival architecture, with many surviving Federal period features.

The house's five-bay facade is fronted by a massive two-story Greek Revival temple portico, with fluted Ionic columns rising to a full entablature.

Its main entrance is framed by sidelight and transom windows, and has flanking pilasters and a projecting cornice above.

A two-story ell extends to the rear; it has less ornate original finishes, which include crown moulding and four-panel doors.

The ell was added, and the house given its extensive Greek Revival treatment, c. 1830-50 by William Rossiter, a prominent local businessman and politician.
