6, St Johns Street

No. 6 St John's Street is a house that has been converted into a shop and offices. It dates back to the 16th century, with an 18th-century front and 19th-century alterations. The building is timber-framed and rendered, topped with a steeply-pitched slate roof that features wide eaves and a moulded plaster cornice. It has an L-shaped plan with a contemporary rear wing.

The exterior consists of two storeys and attics, with a two-window range. The windows are sashes in flush cased frames, each with a single vertical glazing bar. There is one similar window on the ground floor, along with a wide 19th-century double shop front that has glazing bars and overlaps with the adjoining No. 7. The building also features two gabled dormers with sashes that have vertical glazing bars and plain bargeboards. A six-panel door is set within a plain wood architrave and is topped by a rectangular fanlight with vertical glazing bars. Above the door and shop fascia is a heavy blind box, along with a scrolled cast-iron bracket for a hanging sign that projects between the upper windows.

At the rear, the two-storey timber-framed wing from the 16th century is rendered and roughcast, featuring 20th-century plain tiles and an end chimney stack. There is also a small two-storey 19th-century extension with a shallow-pitched slate roof.

Inside, there is no cellar. The front range was originally jettied and is divided into two wide bays, with two rooms on the ground floor that have exposed main beams featuring shallow double roll mouldings. A similar moulding can be found on the main beam in the rear wing. A beam with ogee moulding and a cresting, located near the front wall of the northern bay, may have been a reversed fascia beam that covered the joist ends of the former jetty. The upper rooms are high, with only plain main ceiling beams exposed, and one room contains a corner fireplace. The attics are plastered.
