30, Out Westgate

30 Out Westgate is a house that has been converted into offices. It dates from the 18th century, with 19th-century extensions. The building is constructed of flint with red brick dressings, and the 19th-century extension features stone quoins. The roof is covered with plain tiles and ornamental crest tiles, and there is a coved wood eaves cornice on the 18th-century section.

The exterior consists of two storeys, with a cellar and attics in the main range, and two storeys in the 19th-century extensions. The 18th-century range has four windows, two of which are blocked on the first storey. The remaining windows have sashes with a single vertical glazing bar, except for one ground storey window that has 12 panes. There are two segmental-headed dormers with three-light casement windows. The doorway features a wood architrave and panelled reveals.

The 19th-century extension on the south side has a hipped roof over the gable end and a square Edwardian bay window with mullions and transoms on the ground storey. An open porch at the angle between the two ranges has heavy moulded balusters in a Jacobean style. Above the porch, there are plaster casts in high relief depicting a man with a plough and farm animals, and a woman with sheaves of corn. These casts are replicas of figures found in the pediment above the Corn Exchange on Cornhill.

Inside, the extensive brick-lined cellars were used during the Second World War as an Air Raid Wardens' post. Most original features within the house are concealed, but one upper fireplace retains a reeded marble surround with paterae.
