13, Quarry Street

No. 13 Quarry Street is a house that has been converted into an office. It incorporates remains from the late 13th century and 14th century within an 18th-century building, which was restored and extended in the 20th century. The front is made of red brick with incised render on the ground floor, and it features a stone-coped parapet that hides a plain tiled roof. The building has two storeys and an attic, with an end stack on the left side.

In the attic, there is one 6-pane sash window under a cambered head, and a plat band runs across the first floor below. The first floor has a 16-pane glazing-bar sash window in an open sash box, while the ground floor to the left features a bowed window. The entrance door consists of six fielded panels surrounded by a thin reeded strip, topped with a transom light and hood.

Inside, the first floor has braced posts supporting a chamfered spine beam, with exposed wall plates. During restoration, a hard chalk wall and doorway were discovered, which appear to be the inner face of an arch with a rebate for a door, providing important evidence of a substantial early house on the site. Only the Church of St. Mary and the Castle are older standing structures in Guildford.

The first-floor room boasts an unusually fine and complete black and white wall painting from the late 16th century, measuring seven feet high by twelve feet wide. It depicts a gentleman in a meadow in front of a town wall, flanked by strapwork panels. The inscription in two decorative panels reads: "Slak not thy tyme nor doe not forgett thy synfull lyfe for to amend" and "O mortall men and wormes meate remember death shall be thy eynde."

Additionally, there is a good early 19th-century circular staircase, and the ground floor features a front room with a four-centred stone fireplace.
