Firths Norfolk West Gun Shop

Firth's Norfolk West Gun Shop is a gun works with adjoining workshops and offices, built in the late 19th century, with some alterations from that period and the 20th century. It was likely commissioned by John Firth, the son of Thomas Firth, for the company Thomas Firth & Sons. The building is constructed of brick with stone dressings and features slate and corrugated iron roofs.

The exterior includes a plinth and an eaves band, with two-storey ranges facing Savile Street, which has 29 bays, a rounded corner with 8 bays, and a three-storey range facing Carwood Road with 7 bays. The Savile Street front features a 9-window range on the left, which includes a canted stone oriel window, two margin light sashes to the left, and six plain sashes to the right. Below this, there is a carriage entrance flanked by single doors with overlights. To the left, there are two glazing bar sashes, and to the right, three more. Further right, five recesses defined by pilasters include two with round heads, five triple glazing bar sashes, and below them, five 20th-century steel casements. There are also five blank lunettes and below, fifteen round-headed windows with 19th and 20th-century triple tilting casements, one of which has been converted to a fire door. The rounded corner has eight segment-headed triple tilting casements on each floor. The Carwood Road front has seven similar casements and a coped gable containing a Diocletian window above. Below this, there is a tilting casement and a blank space, flanked on the left by four restored windows and a fire door.

The interior has not been inspected. Historically, the Gun Shop was specifically built for forging heavy artillery barrels and housed two exceptionally large 25-ton steam hammers. By the mid-1870s, Firth's had become the leading gun forgers in the world, producing many record forgings in the shop.
