Plas Dolguog

Plas Dolguog is an early 17th-century house comprising several ranges, built around a courtyard arrangement.

The main early 17th-century range is a 4-unit structure of 2 storeys with attics, rendered and covered with old slate roofing. It has a tall lateral stack to the rear elevation and a small stone stack at the left end. The original entrance position is unclear, but the current entrance is positioned to the right of centre, in the angle with the front wing. A porch canopy with slate roof on timber posts forms a lean-to against the wing, sheltering a half-glazed panelled door inside. The windows are 12-pane hornless sashes of variable size; one appears to the right of the entrance with two more on the upper storey. A datestone is set between the upper storey windows. To the left of the front wing, single windows to ground and upper storey are not vertically aligned, with skylights breaking the roof pitch. At the rear, the rendered lateral stack sits slightly right of centre. The first floor features sash windows set under gablets with wave-moulded barge boards; a wide gabled bay to the far left (a later addition) contains a 4-pane tripartite sash. Above the gablets sit small gabled attic dormers decorated with Y-tracery and embellished barge boards, each containing 2-light wooden casements (the left one is plain-glazed). The ground floor is largely obscured by late 20th-century wooden conservatories built on stone plinths, and a low block to the far right with shallow-pitched roof.

The front wing is 2-storey, rendered beneath a shallow hipped slate roof with overhanging eaves. A canted bay with modillion cornice to the front contains French doors with large-pane wooden glazing, with a tall tripartite sash window above. On the right return, beneath the porch, stands a narrow 12-pane sash window. A later single-storey lean-to with shallow-pitched roof adjoins the left return, with a canted south-west angle containing a 3-light transomed window. At the left end of the left return is a late 20th-century half-glazed door beneath a lean-to porch canopy, with a 20th-century top-hung window to its right and another to the upper storey.

The west block is said to be late 17th-century, though its external character appears later. It is 2-storey with a large stone end stack and is lower than the main range, set slightly back. The front has a 16-pane horned sash to the ground floor; a canted oriel window with late 20th-century glazing sits to the left of the upper storey, with a 4-pane sash to its right. The rear features a doorway to the left with a split door, a small 4-pane window immediately to its right, and a 12-pane sash to the upper storey. A narrower 2-storey range adjoins to the west, with a lean-to to its front and a 20th-century wooden window to the rear ground floor.

The east block is 2-storey with a rendered end stack to the right and a small brick stack to the left, which may relate to the original building. The front has 12-pane sash windows aligned to each storey; the rear has a 16-pane sash to the lower storey, above which rises a large tripartite sash. A 20th-century half-glazed wooden door is offset to the right of the gable end, with an adjacent small-pane casement.

The entrance leads into a narrow stair-hall with an open-well staircase to the rear, featuring plain balusters, newel and moulded handrail. The ceiling has been raised with moulded coving, but the left wall retains an original cross-beam deeply chamfered with lamb's tongue stop. A corridor extends left, immediately right of which lies the original hall. This has a large lateral stone fireplace with chamfered timber lintel, and the ceiling is fitted with 3 deeply chamfered cross-beams. On the first floor, one bedroom retains part of a box-panelled partition; old lath and plaster infill was discovered here. In the attic, substantial tie-beam trusses with collars and raked struts are visible, their timbers pegged together; parts of box-panelled partitions also survive.
