Plas Heaton Farm

T-shaped house of one-and-a-half storeys; of limestone rubble and partly brick construction with pebble-dashed principal elevations; slate roofs with slab-coped gable parapets having curved kneelers. Central brick chimney with early C20 heightening and a projecting, gabled end chimney to the rear arm, with brown sandstone stack (reduced). The S (yard-facing) front has three 12-pane unhorned sash windows to each floor, the upper ones breaking eaves and contained within hipped dormers; similar ground-floor window to the R gable end. The L gable end has a projecting brick gabled chimney with modern top section; this partly overlays an earlier, C16 or C17 window (now blocked) with pegged oak frame.

The rear wing has a C19 outshut to its W side with modern stable-type door and a small-pane modern window to the L; tall brick chimney at the corner. The corresponding eastern side has a single-storey early C20 porch extruded in the corner, with part-glazed contemporary door. Modern multi-pane wooden window to the ground floor R, with a 12-pane dormered sash above, as before; 12-pane fixed window to the L.

In the angle between the wings is a C17 well stair with flat pierced balusters and geometric patterning of conjoined ovals and rectangles to the string; square newels with S-shaped relief carving. On an ex-situ wooden plaque affixed to the stair: HIM:AN:DO:1680 (for Heaton). It is likely that the staircase, probably second-quarter or mid C17 in origin, was updated and simplified c1680 when the house was remodelled. Two-panel fielded cupboard door, probably mid C18.
