Description
The Hawthornes is a two-storey building constructed of rubble with bathstone dressings, featuring a tiled roof with plain and scaled bands, tiled ridge crests, and rubble chimneys with freestone quoins and elaborate heads. It has an eaves balustrade and is adorned with mullioned and transomed windows, where the mullions are treated as pilasters in the Northern European Renaissance style. The windows generally retain stained glass in the upper lights.
The entrance front faces St James’ Gardens to the east. On the right side, a gable set forward includes a niche and a three-light window on the first floor, while the ground floor features a splayed bay with a balustrade and mullioned and transomed windows with stained glass in the upper lights. To the left, there is a small gable with a narrower three-light window on the first floor, alongside a central window with a segmental head. The ground floor on this side is set forward to align with the right bay and also has a balustrade.
The central doorway is flanked by pilasters and has a keystone above a segmental head, leading to a panelled door with an overlight and marginal glazing. To the left of the doorway is a three-light mullioned and transomed window. The right return features a tall chimney followed by a gable, which has a two-light window on the first floor and another two-light window on the ground floor. At the rear, there is a long lower wing with two first floor windows, while the ground floor is obscured by a modern flat-roofed extension.
