Royal Arsenal East Riverside Guard Room

The Royal Arsenal East Riverside Guard Room is a guardhouse built in 1814, possibly designed by James or Lewis Wyatt. It is constructed from yellow and red stock brick, featuring a limestone ashlar cornice and parapet, with a 20th-century flat roof. The building has an octagonal single-room plan and is a single storey with an 8-bay range. It includes a plinth, cornice, and blocking course, with the sides displaying rubbed brick segmental-arched recesses. The south entrance bay has a mid-20th-century doorway, while the other sides have segmental arches leading to mostly blocked 6/6-pane sash windows. The interior has not been inspected. Historically, this guard room was one of a pair that flanked a flight of steps leading up from the river, which served as the original main entrance to the Arsenal. It once featured an 8-sided hipped roof and a central stack.
