Boston Hall East Wing Mews Cottage West Wing

This is a large house with a service wing, dating to the late 18th and early 19th centuries. It is located on the south side of Boston Spa High Street, and is currently used as offices and dwellings. The building is constructed from coursed squared magnesian limestone, with graduated slate roofs.

The main house, Boston Hall, is a two-storey-and-attic structure, five bays wide. It features a central six-panel door with a fanlight of radial glazing bars, set within a Doric, open-pedimented stone doorcase. The other bays have sash windows with glazing bars under grooved wedge lintels, each with a fluted keystone. A dentilled eaves cornice runs along the top of the building, and the gables have shaped kneelers and ashlar copings, with yellow-brick end stacks.

To the left, set back, is a two-bay wing (the East Wing). It has a large projecting lateral stack, to the left of which is a panelled door in a corniced doorcase, and a six-pane sash window to the first floor. The wing to the right (the West Wing) is three storeys high and two bays wide, set back and terminating at the rear in a lower, separately-roofed house, which is the Mews Cottage. The West Wing has a hipped roof to the right end. The front of the West Wing contains a panelled door on the left, set within a corniced doorcase, and an unequally-hung, nine-pane sash window with a flat arch. The ground floor and first floor have sashes with glazing bars, while the second floor has six-pane sashes.

At the rear of the East Wing is a margin-glazed French window flanked by tall unequally-hung 15-pane sashes, alongside unequally-hung nine-pane sashes to the first floor. The rear return of the Mews Cottage has a six-panel door with a four-pane overlight in a corniced wooden doorcase, alongside four-pane sashes and a hipped roof.

Inside the main house, Boston Hall, there is an inner door beneath a fanlight with radial glazing bars. A cantilevered wooden staircase features turned balusters and a wreathed and ramped handrail. Several contemporary fireplaces are located on the first floor, including one with Delft tiles and another with a Neo-Classical panel on a wooden surround, adorned with drops and small lions' heads.
