Two storey house with single storey service wing to rear and single pitched addition to R (NE). Coursed boulder construction including massive stones to the base of the walls; stone lintels and sills. Roof of small slates with stone copings and square gable stacks with dripstones and capping. The main part of the house is a 3 window range with the principal elevation facing SE, the ground floor has 9-pane horned sash windows flanking a wide doorway housing a replacement boarded door with long tulip headed hinges; 1st floor windows are small 4-pane casements set directly under the eaves. There is a similar 1st floor window in the L (SW) gable return and to the rear there is a 6-pane ground floor window with a single, shallow 3-pane light above, offset to L (NE) end of the range.

The single storey service wing to rear is of similar construction and has a tall gable stack at the junction with the added range to rear. The main part of the service wing has a recessed stable door at the L (SE) end of the NE wall, the opposite wall has a 6-pane casement window to L and a small 4-pane fixed light to R. The added range beyond has a boarded door to R (NW) end of the NE wall and a narrow fixed light in the NW gable apex.

The single pitched stable addition at NE gable has a central boarded door with a ventilation slit to L along NE wall and a large 20-pane light in the R (NW) return.

Original layout of hall, cross-passage and two service rooms modified successively by creation of parlour, and then by creation of a single large room, but the framed ceilings of the original rooms remain, as does the stone chimney stair adjacent to the former hall fireplace. Massive hewn chamfered bressumers to fireplaces at both ends, that to the former parlour dated 1770 and L LL (for Lloyd). First floor has 3 collar trusses, one of which is grooved for a partition showing that the original layout was of 2 rooms. Wall panelling in one room said to be a replica of the earlier panelling, replaced in the late C20.
