Herridge House, Sherbourne House, Seymour House and Calebs House

These four houses, Herridge House, Sherbourne House, Seymour House, and Calebs House, were originally part of an asylum. They were built between 1833 and 1835 for Dr. Henry Hawes Fox, designed by Bristol architect Charles Underwood. The houses are constructed of ashlar, with lined-out render, and have a hipped slate roof on the central block, with flat roofs elsewhere.

The central block is two storeys and an attic, with seven windows. The lower two-storey wings each have five windows. Sashes are used throughout. The central block has a rusticated ground floor and a large central bow, now divided into two porches, which supports a loggia with a fluted composite order. The ground floor windows have pelmets, while the first floor has pilasters. Windows have architraves and are set beneath a panel, topped by a cornice and a balustraded parapet. The wings have four plain windows set back, with end pavilions. Modern glazing and doors have been inserted at ground floor level. The first floor of the wings features windows with frames and pediments, flanked by pilasters, a cornice, and a section of balustraded parapet. Similar first floor end elevations feature panels above the windows, while the ground floor has been patched and adjoins 20th-century garages, where single-storey links to the end pavilions were demolished.

The rear elevation of the central block has only five windows, all sashes. The central three windows project forward, while the outer two are under a fragment of an Ionic colonnade with balustrades and a parapet. The middle three windows support a tetrastyle composite loggia with an entablature and cornice, with windows behind, the centre one of which is blank. Windows with architraves, set below panels, feature alongside windows with pediments flanked by paired pilasters, terminating in a balustraded parapet. The wings have five plain windows set back, followed by an end pavilion similar to the front.

The interior has been extensively modified.
