No. 13 Castle Street is a house dating from the 17th century, with an early 19th-century rear addition and refurbishment around 1900, along with 20th-century changes to the windows. The building is timber-framed and plastered, topped with a peg-tiled roof and features a red brick stack. It has a rectangular plan with a street-facing range and a slightly inset rear addition. The house is two storeys high.

On the south elevation, there are two windows featuring 20th-century two-light casements with roll-moulded frames and a central stile, each consisting of four panes. The ground floor has a doorway with a moulded frame and a plain boarded door, while a 19th-century stack is located at the eastern end of the roof apex.

The north elevation features an early 19th-century two-storey lean-to addition with a slate roof, which includes a first-floor window with a moulded architrave that now has a 20th-century plain casement. The ground floor has an early 19th-century flush bead moulded door flanked by single light 20th-century casement windows. Inside, the roof displays a well-made 17th-century side purlin structure with curved wind braces.
