Barracks and offices for Royal Engineers, now offices. Dated
1846, restored 1990. Red brick with grey header bricks in
Flemish bond. Low pitched Welsh slate hipped roof. Late
Georgian style.
PLAN: central open courtyard with stair and single-depth rooms
to 3 sides.
EXTERIOR: 2 storeys, 7 bays, centre 3 bays project.
Symmetrical front with matching sides. At centre is a 2-leaf 6
panelled door with fanlight under gauged brick round arch set
in later projecting porch with stone coped facing gable,
moulded stone apex with inscribed shield which reads 'R.E.
Office'. To left and to right six 12-pane sashes each set
under gauged brick flat arch. First floor has 7 similar
sashes. The centre 3 bay projection has stone band at first
floor, brick band over first floor and facing stone gabled
parapet, flanking bays have brick band, stone cornice and
rendered block parapet. Left and right returns are similar
with central pediments, on left of right return is a later 6
flush panel door with margin glazed overlight.
INTERIOR: largely complete interior with a large open central
stair hall containing an interesting cast-iron Imperial stair,
with galleries to 3 sides on first floor and stairs leading up
on 4th side, with cast-iron risers, tread balusters and
handrail, and original joinery and plasterwork.
HISTORY: the exact purpose of this precisely planned building
is not known, and Engineer's barracks are rare. The patterned
brickwork is similar to that found on the c1810 stores at the
former Ordnance yard at Gunwharf. Of considerable historic
interest, and for its unusual plan form and stair.
