The Andrew Clark House, also known as the Haskell House, is a historic house on Ross Hill Road in Lisbon, Connecticut. It is a 2-1/2 story wood frame structure, five bays wide, with a side gable roof and a large central chimney. A 1-1/2 story ell, once a freestanding house, was added in the 18th century and extends to the rear. A second addition extends even further from the ell; it was added in the 20th century as a sensitive contribution to the house, and used period parts from a Rhode Island house. The main features of the house's main facade are a second-story Palladian window, and a pavilion sheltering the main entrance. Although the basic structure of the main house is Georgian, its styling is more Federal, reflecting the transitional period of its 1798 construction date.
