No 11 Westgate Hill including attached portion of West Gate to right

No 11 Westgate Hill, which includes an attached portion of West Gate to the right, is a house located at the end of a terraced row. It is constructed of rubble stone with some areas of cement render and features a slate close-eaved roof that is continuous with No 10. The house has two storeys and a three-bay front that is offset to the left, displaying a slightly irregular arrangement of sash windows. The entrance consists of a board door, which is flanked on the left by a 12-pane sash window and closely on the right by a smaller 4-pane sash window. The left window has stone voussoirs, while the door and right window are supported by timber lintels, with slate sills beneath each.

On the first floor, there are 12-pane sashes in the centre and to the right, and an 8-pane narrow sash to the left. The left sash is roughly aligned, the centre sash is slightly to the right of the door, and the right sash is well to the right of the ground floor right window, featuring 19th-century red brick jambs.

To the right side of the house, a massive block of masonry made of roughly squared stones projects outward. Adjacent to this is the eroded jamb of the West Gate, which is square and has a cambered arch with rough stone voussoirs. The house is raised on a platform above bedrock, with a rubble stone parapet that gently rises from the top of stone steps aligned with the right bay of No 10, next to the medieval West Gate projection.

The right end wall, which is the outside face of the town wall, is made of rough masonry and has one ground floor 12-pane sash window. There are also two square blank recesses located just inside from the West Gate jamb. The interior has not been inspected.
