Guard House

The Guard House, built in 1861, is a significant structure located at the main north-east entrance to the gunboat yard. The design was created by the Admiralty Works Department, led by Colonel Greene and William Scamp, who specifically designed the guard house and police barracks. The brickwork was contracted to Messrs Rigby of London.

Constructed from red brick laid in Flemish bond, the building features limestone dressings. The guard house and police barracks were originally designed as mirror images of each other, each roughly square with a central courtyard.

The exterior of the single-storey guard house includes a colonnade of eight bays with round arches supported by square piers. The piers have dressed stone bases and springers for the arches, and there is a stone band at the base of the parapet. The hipped roofs and chimneystacks, which have brick detailing at their heads, are partially visible. The windows around the building feature round or segmental-arch brick heads and stone cills. Notably, six of the colonnade archways on the northern block have been infilled with brick and small windows as part of a later modification.

The interior was not inspected.
