Description

Nos 14, 15, 16, and 17 High Street Inferior are two main sections of buildings. The right-hand structure, Nos 14 and 15, known as Warwick House, dates from the late 19th century. It features a rear wall made of stone with brick dressings, while the classical-style stuccoed facade facing High Street Inferior has three storeys and an attic with four windows. The slate roof has two gabled dormers, and there are projecting bracketed eaves and a band at the second floor level. The window openings have moulded stuccoed architraves, and the horned sash windows have margin glazing bars in the upper parts. The late 19th to early 20th century shop front includes two wide canted bay windows and a central doorway set within a casing of pilasters, a panelled fascia, and a bracketed cornice, with curved heads to the window lights.

At the rear of Warwick House, facing Lion Street, there is a much lower detached wing of two storeys and an attic, likely from the 19th century. This wing has a rendered elevation with one bay facing Lion Street and a slate roof with a gabled dormer. It features horned sash windows.

The left-hand or north-western structure consists of two ranges built back-to-back. The front range has a stuccoed facade facing High Street with two storeys and five windows. The windows have moulded architraves and are horned sash windows, with smaller sash windows on the second floor. There are two shop fronts on the ground floor. The rear range, facing Lion Street, is earlier and has a symmetrical front from the early to mid-19th century. It has three storeys, three bays, a pebbledash finish, a slate roof, and projecting eaves. There are bands at the first and second floor levels and a plinth. The small-pane sash windows are four panes wide with smaller sashes on the second floor. On the ground floor, there is a broad segmental-headed vehicle entrance with a six-panelled door in the central bay.
