High House is a substantial Renaissance farmhouse of 1675. The idiosyncratic design with its exceptionally high roof-ridge is unique in Monmouthshire. The remarkable dated porch of 1675 has enriched dentil decoration similar to the fireplace, window and door-surrounds at Great Marlborough, Grosmont, and may be work of the same craftsman. It has painted render and an exceptionally high, steeply pitched slate roof. In the centre of each slope are massive rendered stacks which have square bases and four, tall, diagonally set flues. A great symmetrical gable front faces south. The wall of the lower gable breaks forward to form the two-and-a-half-storey entrance front. The monopitch lean-to roof has three twentieth century rooflights and is hipped, the slope of the hips is carried back on each side to merge with the roof of the main house. The first floor has three 2-light mullion windows with 2+2 pane casements and the ground floor (centre) has an impressive single storey gabled porch flanked by 3-light sunk chamfer mullion windows on each side: window to left with 2+2+2 panes, and to right with 6+6+6 panes. The timber framed pediment carries an unglazed wooden oculus and an ornamental pendant at the apex, dated 1675. The bargeboards and door-head are elaborately carved with enriched dentil decoration. The door jambs have reserved panels which carry enriched decoration, featuring a disc with arabesques in relief. The inner entrance doorway has an elaborately decorated surround with complex ovolo and ogee moulded jambs and runout stops with arcaded flats. Inside, Fox and Raglan record the exceptionally unusual double-pile layout, with centre staircase flanked by fireplaces separating front and back ground-floor rooms on each side. An exceptionally fine dated dog-leg stair of 1675 has chamfered newel post with scroll stops, splat balusters and carved ornamental band on outer face of string.

It is highly graded as an exceptionally important and well-preserved Renaissance house of 1675 with highly unusual plan and very fine porch.
