Cottage. Late C16, probably C18 stair block, minor C19 and C20 modernisations. Footings and entrance front up to first floor level of coursed sandstone. Rest is timber-framed and mostly exposed; it is brick- nogged at ground floor level and plastered infill above; the entrance front is hung with peg-tile above first floor level.

The larger main living room to left (north east) has a large projecting gable-end stack. Unheated service room to right now contains the present kitchen and entrance through right end behind the kitchen. Probably C18 stair block projects to rear of the service end.
2 storeys with attics in the roofspace and cellar.

Ground floor right window (to the kitchen) a C20 casement with no glazing bars. Exposed large framing with evidence that it once had curving tension braces at first floor level. Tall roof is gable-ended. The left end gable is timber-framed and the chimneyshaft rises from the stack free-standing. The right (south west) end is the entrance front and the doorway to right contains an old, probably C19, plank door with coverstrips. The stair turet is probably C18 brick. Some repaired closed studded framing in the rear wall.

Large fireplace with chamfered oak lintel.
