Description

Nos. 27 and 29 Monnow Street are two-storey buildings with an attic, likely built in the 18th century. They are completely rendered and painted, possibly over timber framing, and feature a plain tile roof with a red brick chimney. The front has a late 20th-century shopfront with a wide fascia, flanked by single-pane display windows above a plain stall-riser on either side of a central door. The door to No. 29 on the left is a modern 'Carolina' style.

On the first floor, No. 29 has two 2 over 2 pane sash windows, while No. 27 has two 6 over 6 pane sash windows. Each building features a flat-topped half-dormer with tripartite steel casements. The roof is steeply pitched, with a rebuilt stack on the right gable. The rear elevation includes a large single-storey extension, where most windows, except for one 6-pane sash, are 20th-century replacements.

During a resurvey in March 2005, only the first floor was examined, which appeared entirely of late 20th-century character. The rear wall may have also been rebuilt, and the attic floor and roof might show signs of earlier construction.
