Plas Newydd Farmhouse

Plas Newydd Farmhouse is a 2-and-a-half storey building constructed of rubble on boulder and rock foundations, dating from the 17th century. It features a renewed slate roof with slab-coped gable parapets and shaped kneelers, along with tall chimneys that have original moulded capping and weathercoursing. The entrance front faces north, away from the farmyard, and includes two ground-floor entrances with boarded 20th-century doors; the left entrance is recessed, while the right has a three-light modern casement window beyond it. Above the right entrance, there is a former similar entrance that has been converted into a window.

The attic floor has a large dormer entrance with a dormer window to the right; both have coped, kneelered gables, and the entrance features a late 19th or early 20th-century boarded door that reuses original 17th-century decorative hinges. The stairs providing access to both the first and attic floors have been removed, with the latter being taken out in recent years. On the south side, which is the rear, there are two windows on each floor, all modern casements but set in their original openings. The attic windows are located within gabled dormers as before.

To the left of the farmhouse, there are remains of a connecting range, which includes a section of wall reduced to a stepped buttress and a masonry mass beyond that shows evidence of an end fireplace and an associated stone corkscrew stair. There are two blocked first-floor windows on the west gable, with a 20th-century single-storey brick lean-to below.

Inside, the left ground-floor chamber features a wide fireplace with a flat, stopped-chamfered bressummer. There is a plain galleried staircase from around 1900 and four-panel doors. Most ceiling beams are boxed, although one chamfered lateral beam has ogee-stops. The attic floor consists of three bays, with one original pegged oak strutted truss that has fine chamfering.
