1, Archery Lane

This is a guard house, later used as a post office and now a house, built between 1901 and 1905. Constructed of red brick with terracotta dressings and a slate roof, it is designed in a Georgian Revival style. The building has a single-depth plan.

The exterior is one-and-a-half storeys high and features a six-window front. It incorporates rusticated brick quoins, a frieze, and coped end gables with a terracotta string and oculus. A verandah supported by iron posts runs along the front of the building. The ground floor has segmental-arched sashes with six panes over six panes. Above the verandah are smaller segmental-arched openings with keystones, rising into the frieze. Two openings on the left have eight panes, while three on the right have fifteen panes. A single-storey section to the left, with a hipped roof, originally contained cells, now incorporating an inserted garage door; a sash window and a barred cell window are visible on the left-hand side elevation.

The interior has not been inspected.

Historically, this building is an unusually elaborate example of a guard house, situated at the Southgate Street entrance to the Peninsula Barracks. The Lower Barracks were occupied from the mid-19th century as a hospital and prison linked to the Upper Barracks, and were largely rebuilt between 1901 and 1905. It forms part of a complete functional group of late Victorian and Edwardian barrack buildings and contributes significantly to the overall importance of the Peninsula Barracks site.
