Pen Dinas

2-storey building, aligned east-west with full-length catslide outshut at rear. Painted roughly coursed rubblestone with slate hanging to right gable end; slate roof with exposed purlin ends. Symmetrical front has central entrance with ribbed door under wide glazed porch flanked by 3-light casements with slate cills and 2 horizontal glazing bars to each light; 2-light casements with same glazing bar pattern in gabled eaves dormers directly above ground-floor windows; integral end stacks, right with slate drip and dentilled brick capping, left rebuilt above drip.

Thick walls to lean-to at rear, which is not in fact an addition as the external appearance of the building may suggest, but the remnant of a single-storey cottage. Plain joists to main part of house, which has C19 straight-flight staircase in line with entrance.
