Plas Uchaf

The house has walls up to 1m thick and unusually large rooms. The later entrance on the E side of the N-S range leads into a small stairhall, with wide straight staircase to rear with close string, moulded handrail and square newel posts. Immediately to the L is a panelled door leading into the parlour which retains 2 chamfered cross beams with ogee stops with fillets, and a wooden fireplace on the R side of the bay window, set at an angle. To the R of the staircase is the doorway into the former hall which retains a chamfered cross beam and reduced, infilled fireplace to N, connected with the truncated lateral stack. A round arched opening to the W leads into the E-W addition, and a doorway from here to the N leads into the long kitchen range which has 2 boxed-in beams. A door in the W side of the kitchen leads into the large lean-to, formerly used for cheese-making, and containing part of a truss and a quarry tile floor.

The main staircase leads to a small 1st floor landing, with panelled doors to L and R. In the bedroom to the L (in the N-S range) is a fireplace set at angle, directly above that in the parlour. It supports a fine over-mantel bearing a coat of arms which retains colour and gilding. A moulded roundel bearing arms is flanked by obelisks and supported on a moulded sill. Outside the roundel, at each corner, is the following: 16 / 03 / RM / MM. To the rear of the landing is the original spiral stone staircase in the projection which leads both up and down. Immediately L of the rear staircase at landing level is a Tudor-headed stone doorway with planked door leading to a narrow room.

Two and 3-storey house of complex form. Roughcast over stone under slate roofs with rendered stacks. The 3-storey E-W range contains the original entrance on its N side, offset to the far R. To its L is a massive lateral stack now truncated. The arrangement of windows is irregular, many of them C20 replacements. The entrance consists of a 2-storey gabled porch (now in the angle with the N service range), open to the ground floor and supported at the angle by a chamfered timber post with ogee stops and 2 ornate cusped brackets. The moulded sill beams have saw-tooth decoration. Inside the porch is an early studded door with strap hinges, protected by a C20 half-glazed door. The upper storey of the porch has a 2-light casement window offset to the R facing N. To the L of the porch are a pair of C20 wooden casements to the lower storey, that to the L under a segmental head. Small 2-light mullioned window to R at 1st floor level. Tiny light with quarries to L of lateral stack at ground floor level. The E gable end of this range has a wide window with large sill to each storey; a 3-light casement to the 2nd floor and mid-C20 metal-framed windows below.

The N-S range is also 3-storey and is dated internally by the coat of arms. It has a full-height staircase projection to the rear (W), whilst a new front entrance was added to the E side in the C18-19 in the angle of the 2 main ranges. It consists of a gabled porch with a part-glazed panelled door under a flat head flanked by side lights with quarries. Above is a small 3-light mullioned window, partly blocked. To the L of the porch are 2-light multi-pane casements to the ground and 1st floors. The S gable end of the range has a 2-storey bay window with pediment (said to have been pargetted) and a high outshut to the L. The bay has French doors flanked by multi-pane lights which wrap around the sides, under a full width moulded lintel. Full width window above with plain glazing flanked by multi-pane lights under similar lintel. Three-light late C20 window to 2nd storey of gable end. To the L are 2-light multi-pane casements to ground and 1st floor of outshut and a tall lateral stack to roof pitch. To the W (rear) is the staircase projection to the L with tiny stairlight to upper storey. To the R is a butt joint marking the end of the staircase projection with the later outshut continuing to the R. Below is a single-storey lean-to with small stack, a planked door to R, small light further R, and large C20 window to L.

Small E-W range, probably for service originally, adjoining W gable end of main E-W range. It is of one-and-a-half storeys with C20 windows under segmental heads, one to the attic and 2 below. In the angle with the N-S range is an added flat-roofed porch.

The long N-S kitchen wing is 2-storey and is not aligned with the main N-S range. It has a large ridge stack. The E side has a late C20 door to the R and a pair of C20 windows to the L. Two earlier horizontal-sliding sashes to upper storey, immediately under the eaves. The N gable end has an external stone staircase leading to a segmental-headed door. Lean-to against rear (W) of kitchen wing with planked door under segmental head to S end, with brick garden boundary wall extending to W.
