From a 2017 Historic England listing assessment report:

"Between the mill pond and the head of Robins Creek are a group of two buildings. These comprise a long, single-storey, workshop building to the S and a large double-height building with a single-storey western range to the N. The southern building with its northern range is shown on the 1864 OS map and expanded westward on the 1898 OS map. By the 1939 OS map it had again been reduced to its current
footprint. The northern building is probably indicated on the 1898 map as part of a larger complex of buildings. On a site plan of 1922 most of this complex had been demolished. The current buildings are marked as a coal shed and adjoining locomotive shed. Tracks are shown entering the locomotive shed and an overhead gantry enters the N elevation of the coal shed. The southern range of buildings are now marked as stores. On the 1954 OS map the northern buildings are marked as a ruin.

Southern building

Exterior: the single-storey southern building is constructed of concrete blocks with red brick
inserts at the wall tops, as a band on the southern gable end and, evenly spaced with concrete
blocks, in the pilasters which support the side and end walls. The eastern elevation onto
Grove Road is rendered with plain square headed windows with multi-light metal frames and a
large goods entrance at the northern end. The western elevation has two windows again with
metal frames. The gabled roof is of slate with skylights. At the northern end is a narrow
single-storey range, built of brick, rendered on the N and E elevations, with a corrugated metal
covered catslide roof.

Interior: the main workshop space has kingpost timber trusses with raking struts supported by
a lateral steel girder of later date. The walls have internal pilasters and there is a fireplace in
the E wall. At the southern end is a foundry pit from the building’s last use as a bronze
foundry. In the north range, used as offices, is a fireplace with 1930s tiling.

Northern building

Exterior: the double-height northern building is rectangular in plan, built of stock brick with a
hipped roof with replacement corrugated metal covering. It is adjoined on the western side by
a brick single-storey range.

The S elevation probably originally had four centrally placed arched openings. The eastern
upper window has been enlarged with a concrete sill. The lower, slightly wider, opening is
blocked and was probably an entrance. The probable lower western opening has been
replaced with a large goods entrance with a steel beam lintel and the upper window is
truncated. Above the windows is an oculus, now blocked. The N elevation had two large
arched windows which are now blocked. A later square window has been inserted between
the windows cutting into the arches. The E elevation has a single arched entrance, now
blocked. The W elevation has a blocked square doorway. The single-storey western range is
also of stock brick with the upper part of the walling of the N and W elevations of later date.
The S elevation is open (now closed with metal sheeting). The N elevation has a number of
low, bricked-up, arched openings. The roof, pitched to the S and flat to the N, is of corrugated
metal sheeting supported on modern tubular steel trusses.

Interior: the walls of the main building are plastered to half their height with a dado-height
moulding. A half-height timber framed structure occupies the SE corner of the interior space.
There are two thick transverse timber beams at the top of the walls, augmented by two later
steel girders below them The timber roof structure survives intact. There is no surviving
machinery."
