Double-pile plan. 3-window front, slightly recessed 16-paned sashes with slate cills to first floor.

This is through a slightly recessed door with 2 lower panels and 3 arched and glazed openings to the top; plain semi-circular fanlight. Left return is slate hung.


C19 fireplaces to front ground-floor rooms. Dog-leg staircase with open string and cut brackets, stick balusters (2 of iron) and turned newels, the larger one on the landing possibly a replacement, lit by a tall round-arched window with the name of Herbert Jones (son of the first tenant) scratched on the glass.

Reasons for Listing

Included as a well-preserved slate quarry manager's house built at the entrance to the quarry itself. The house is a polite building exhibiting features typical of modest rectories and gentlemen's houses of the period; makes good use of the local material (slate).
