Old Grammar School

The Old Grammar School, now a private house, is located on Amesbury High Street and dates from the late 18th century. The building is constructed of chalkstone and brick, with the front roughcast and painted. It features a tiled roof and stands two storeys high with an attic. The front has two narrow bays and a three-bay rear wing, with the entrance centrally located in the rear cross wing.

The front elevation includes a plat band and brick dentilled eaves, with 16-pane replacement sash windows on the ground floor and 12-pane sash windows on the first floor, all with flush boxes and applied timber shutters. The roof has a gable stack to the left and is half hipped to the right, with a hipped dormer. The rear block is made of chalk blocks with brick quoins and includes a six-panelled door, 12-pane sash windows, one 16-pane sash, and a gable stack, along with one dormer.

Inside, the building features 18th-century doors on the ground floor. The rear range has diminished principals in the roof, with one tie and clasped purlins. Notably, Joseph Addison, the poet, essayist, and statesman, is said to have attended the grammar school while it was located in the south transept of the church before being moved to this site in 1807.
