Plas Newydd

Interior extensively remodelled c1900 as a result of the house's ruinous state by the end of the C19. All ceilings, floors, beams and roof structure are renewed, except for the collar-beam truss and chamfered purlins above the restored oak staircase; hall was until 1991 stone flagged. All internal partitions are also c1900 except for a fragment of plank and muntin partitioning adjacent to the staircase on the ground floor. Single large room on first floor has panelling of c1900 and there are 2 fireplaces, that to south-west with the carved emblem of the semi-mythical C10 warrior, Cilmin Troedd Ddu, and the date 1637. His arms appear again in a plaster shield on the second floor, this time with the initials TG and the date 1632, Thomas Glynne claiming ancestry from Cilmin Troedd Ddu; the room in which the shield is set and the landings on both the first and second floors have reused C17 panelling, some of it with foliated patterns in semi-circles.

Original 3-storey and attic rectangular plan structure of 4 bays, aligned roughly north-west to south-east and possibly incorporating an earlier structure; 2-storey porch projection on north-east (entrance) front and similar but wider staircase projection on south-west side. Irregularly coursed rubblestone with buttered pointing (parts formerly rendered) with outlines of former roof pitches visible to gable ends; slate roofs with stone-coped verges. North-east elevation: tall gabled porch roughly to centre with room above entrance has 3-light wooden mullioned and transomed leaded windows (like virtually all windows in house renewed c1900) to front and returns and Gothic head to doorway (also c1900); stone water butt adjoining porch to right. Massive projecting lateral chimney immediately on left with tall shaft to top, the small space between on the ground floor infilled with a cloakroom; cross-windows to far left and right, repeated as 3-light windows on first and second floors, with on latter a further 3-light mullioned and transomed window above and to left of porch roof, those on second floor all of reduced proportions. Similar fenestration to north-west gable end; cross-window to right on ground floor, two 3-light mullioned and transomed windows on first floor with centrally placed cross-windows to second floor and attic, latter of reduced proportions; 3-light window to ground and first floors of south-east gable end and small cross-window to attic, both gables with integral end stacks. South-west elevation is most regularly composed with three 3-light mullioned and transomed windows on each floor, one tier to left and 2 to right of staircase projection and chimney, albeit that several of the windows are of different sizes (window to lower left in fact a cross-window); lead rainwater head dated 1632 to downpipe between 2 right tiers of windows. Gabled staircase projection has 3-light mullioned and transomed windows to front and right return, former above a tall narrow lean-to (c1900) with 2 cross-windows at front and to the left a pointed doorway approached by a contemporary straight flight of steps; prominent lateral stack immediately to left of staircase projection, similar to that on north-east elevation but flush with main wall.
