Naval House

Naval House, formerly known as the Municipal Offices, is an early 19th-century building that served as the dockyard owner's house. It features red Flemish-bond brickwork and hipped Welsh slate roofs, standing three storeys tall with a low attic on the second storey and plain parapets, presenting a symmetrical front.

The exterior includes a second floor with a five-window range, although the windows on the south-western half of the facade are now blind on all floors. The three remaining windows have double-hung sashes with a central vertical glazing bar and flat rubbed brick arches. The first floor features a central elliptical rubbed brick arch that contains a three-light 20th-century window, flanked by two double-hung sash windows. The ground floor has two similar double-hung sash windows on either side of a large semicircular-arched brick entrance, which is set on painted impost blocks. The entrance door has six raised-and-fielded panels beneath a large Adamesque fanlight. There is a tarred plinth and a flight of five steps, two of which are made of stone.

To the south-east, there is a contemporary lean-to, while the north-west flank has a two-storey, slightly recessed block with a double-hung sash window on each floor and an up-curved parapet against the main block. A large stack is located at the southern end of the main part of the building. At the northern corner of the original range, there is a large mid-19th-century three-storey extension, also in red Flemish-bond brickwork with block pointing, featuring tripartite and conventional double-hung sash windows with margin glazing and a slate hipped roof.

The rear of the early 19th-century range has a three-storey bow projection with double-hung sash windows that also have central vertical glazing bars. In front of this projection is a two-storey cast-iron segmental plan verandah with a lead tented roof supported by lattice. The ground-floor level of the verandah features interlocking back stays with rosettes at the intersections, many of which are now missing.

Inside, the building boasts a semicircular cantilever well staircase with a continuously curved soffit, stick balusters, a wreathed handrail, and a circular roof light over the landing.
