80, Guildhall Street

This is an early and later 18th-century house, now used as offices, situated in Guildhall Street, Bury St Edmunds. The main house is built of red brick with a slate roof and moulded eaves. It has three storeys and cellars, with a symmetrical five-window front. The ground and first floors feature 12-pane sash windows within flush moulded cased frames, while the second floor has smaller 16-pane sashes. Raised brick bands separate each storey. A central door, with a rectangular fanlight featuring ornate glazing, is set in deep reveals and approached by three steps with wrought-iron handrails; it is sheltered by a flat cornice hood supported on shaped brackets, including a 18th-century wrought-iron lamp holder. A three-storey stair wing with a hipped roof projects from the centre of the rear wall, and there are 20th-century extensions to the rear.

To the south of the main house stands a three-storey block, previously listed separately but now considered part of the same premises, likely an extension. This section uses white brick to the front and side, red brick to the rear, and has a slate roof with a parapet and brick dentil cornice. This block features early 20th-century three-light casement windows with transoms, set within segmental-arched brick surrounds, and its doorway has been blocked. A small, flat-roofed, single-storey extension from the 18th century projects to the north of the main house, positioned behind the linking wall of the adjacent property at No. 81. This extension features an open arcade with pillars along its north side.

The interior includes a partly brick-vaulted cellar, with a higher ceiling to the south, and retains 17th-century ceiling beams. Many original 18th-century features remain, including six-panel doors with panelled surrounds—some with eared architraves—panelled window shutters with original metal fittings, and cornices with egg-and-dart or later foliage decoration. One ground floor room has a heavy modillion cornice and an alcove with fluted Doric columns and fret decoration to the fascia. A substantial staircase runs the full height of the building, featuring turned balusters, ramped moulded handrails, open bracketed strings, and panelled dadoes. A thick wall, possibly of stone or flint, runs through the rear of the south end of the building and is likely a continuation of a medieval stone wall found within the neighbouring property at No. 79. A stone return wall may also exist between the white brick extension and the main front of the building.
