[3] The building was designed for the Royalton Memorial Library Association in the Colonial Revival style by Louis Sheldon Newton, a locally-born architect.

The exterior is decorated with cement quoins, and the roof is hipped, with three gabled dormers, on the northwest, northeast, and southeast sides.

[4] The building's first floor has a welcoming feel to it, with a brick fireplace, armchairs, and a classically detailed archway into another space, formerly housing the children's area, and prior to that, the town historical society.

The ground floor formerly held town offices, and became derelict and unusable, only housing surplus books, until the library's 2019 renovation.

[5] In 2016, the library hosted a small exhibit about Louis Sheldon Nelson, architect of the building and other local landmarks, including the present-day look of the Old Constitution House.
