Cerrigllwydion Hall

Double-width entrance hall (formerly divided) with twin arches off to rear; plain architraves and cornice. Adamesque fireplace of grey figured marble to the drawing room (leading off to the L); plain cornice, 6-panel door. Double-doors lead from the hall to the former dining room. This has a Regency reeded doorcase, a plasterwork cornice with palmette decoration and an Adam-style plasterwork ceiling rose. Classical chimneypiece of white and grey marble with relief-carved frieze decoration. Leading off from the hall to the rear is a service corridor and the principal stair; of dogleg type with mahogany rail, stick balusters and oak treads and risers.

Medium-sized, 2-storey country house. Of brick construction with scribed stucco to the main elevations and plain, rendered chimneys; hipped slate roofs, that to the principal section with deep, feathered eaves. The house consists of a main 3-bay block with lower service ranges adjoining to the R and rear around a small light-well. The main section has a symmetrical facade with an advanced central (entrance) bay. This has a shallow gable with deep verges, and has a stone plaque inset in the apex bearing the initials E E and L, together with the date 1787. C20 arched, boarded double doors to the entrance, with 6-panel door within, having narrow, flanking 4-pane sections, these and the latter part-glazed. In front of the entrance is an early C20 tetrastyle portico with slender Tuscan columns supporting a flat roof with moulded and dentilated cornice; modern flanking urn finials. Primary 12-pane recessed, unhorned sashes to both floors, those to the ground floor and above the entrance with C20 8-pane outer casement sections; projecting stone sills. The SE elevation of the main block (to the L) is of 3 bays, the two right-hand bays having a similar portico projection and the left-hand bay being recessed; windows and secondary glazing as before.

Adjoining the facade of the main block to the R is a single-storey dining room block with hipped-roofed, canted bay; 8-pane sashes with 8-pane outer casements, that to the R extended full-length to 10 panes in a French window arrangement. Hipped return (NW) with 8-pane sash plus casement, as before. Adjoining this to the R, and advanced slightly in front of it, is a 2-storey, 2-bay section, hipped and stuccoed in the same manner. This has a shaved left-hand corner to the ground floor with an 8-pane glazed entrance; plain 2-pane later C19 sash above. The R bay is occupied by a 2-storey canted bay with 8-pane sashes and narrow 4-pane side sections.

The rear of the main block is roughcast and has asymmetrically-placed windows. These include a near-flush 16-pane sash and a 9-pane round-arched window with intersecting tracery lights. Adjoining to the L and advanced at right-angles with the latter, is a 2-bay section of a partly-demolished wing, the lost section of which was undergoing reconstruction at time of survey. Its (original) SW side has two 8-pane casements and a 12-pane sash to its first floor. Between the former is a reset, renewed stone plaque with the carved initials E, E and L, together with the date 1783. The ground floor has a modern conservatory (partly overlapping the rear of the main block), with associated verandah; modern part-glazed doors within.
