Ashlawn, also called the Joshua Perkins House, is a two-story, central-hall frame farmhouse dating from the 18th century in Hanover, Connecticut. The house's namesake is its first owner, Joshua Perkins, a farmer and son of the prominent Captain Matthew Perkins, a farmer and founding member of the Hanover Society. Ashlawn's main house has a five-bay front facade with pilasters supporting broken-base pediments. The inside has well-documented woodwork for its moldings and wainscotting. The house has integrated an older structure, likely a central-chimney structure built in the second quarter of the 18th century, as an ell.
