Plas Colwyn

Two-storey, 3-bay Regency villa, with storeyed lean-to pavilion wings recessed to the sides. Of coursed, rough-dressed stone blocks (originally stuccoed) under a shallow-pitched, hipped roof of graded slates; deep bracketted eaves and plain end chimneys with weather coursing. Symmetrical facade with central entrance to raised ground floor, via 8 slate steps; modern 6-panel door (upper 4 glazed), with rectangular fanlight with decorative intersecting glazing bars. The original 12-pane unhorned sashes survive to both floors, all with projecting slate sills; those to the first floor are slightly smaller and are tucked under the eaves. Narrow, horizontal basement lights flank the entrance, with modern glazing. The flanking pavilion wings are of 2 low storeys with lean-to slate roofs. That to the R has a modern part-glazed entrance with an original 16-pane sash above; that to the L has a similar sash to the ground floor and a fixed (later) 8-pane window above. This side has a modern window under the eaves on its L return, and has a small single-storey lean-to addition extruded in the rear angle between it and the main block.

The interior was not inspected at the time of survey.
