The stone work is of high quality, although the stone is laid random
rather than coursed, the individual stones are large and yet have
tight joints. This shows the quality of building skill used - most
random stonework was of smaller stones and had broader jointing,
mainly because they were usually then rendered; only later was
render removed and new pointing used.
The rough-dressed quoins have a nice contrast in colour and the low
arched lintels complete what I think is an attractive building. The
roof tiles are unusual, similar to double roman style, but modified
to allow for staggered horizontal coursing, whereas normal double
roman tiles are laid with straight vertical joints. Also the rafter
ends are exposed, which again is unusual for Castle street.
Looking back at early maps, it appears that an earlier building here
was larger than the current one. It appears to be double fronted.
Both the 1750 illustrative map and the 1840 tithe map show this
larger building. But by the 1880 map, this building shows as it is
now, which obviously suggests the old building was demolished and
the current building was built between 1840 and 1880. Or possibly
there were originally two adjoining buildings that were replaced by
just the one?

Because the building is set back from the building line of the rest
of Castle street, it is partly hidden from the east side. The only
photos showing this from higher up castle street only really show
the western gable wall. There has not really been much change other
than the present first floor window in the gable wall, which I think
was only installed after 2000.
