Description

29 and 30 are shops with offices above, built in the 19th century. The building has three storeys plus attics and is constructed of brick with bathstone dressings, all of which are painted. The façade features five windows arranged in a 2-1-2 grouping. There are three gabled attic dormers, along with a parapet and cornice. The windows are set back between panelled splays that have corbel heads. A panelled band runs between the second and first floors. The first floor windows are similar to those above but have more ornate heads.
