Description
Llanddewi Court is a house of probable 17th-century origin, with later additions and alterations. The main part of the house is a tall, two-storey building, rendered and painted over local rubble stone, with a Welsh slate roof. The front elevation has three windows, with a gabled porch inserted between the second and third windows from the left. The windows vary in size, and although all are modern 2-light casements, some of the window openings may be original. The porch, added in the late 20th century, provides a lobby-style entrance against the main chimney stack. A bay to the right of the porch is believed by Fox and Raglan to be an extension from the 19th century, but this is unconfirmed. The steeply pitched roof has a small stack centrally to the right. The left-hand gable has a small casement window on the ground floor, and the right-hand gable has a matching casement on the ground floor, with a larger 2-over-2 pane sash window above. The rear elevation of this wing has two small, probably 19th-century, lean-to additions on the ground floor, and a 3-light casement window above.
The single-room rear wing has a 3-light casement window under an oak lintel, in an original opening, with a 2-light casement above. It has a steeply pitched roof and a large stack on the gable end to the right. A blocked 3-light window with diamond mullions is within the gable wall, which likely lit the staircase and was probably never glazed. Other 17th-century windows previously recorded by Fox and Raglan have been replaced. The rear wall of this wing contains a small 2-over-2 pane sash window on each floor.
Alterations to the ground floor of the two-unit wing include the insertion of a 19th-century straight flight staircase into what was originally the hall. The fireplace has been altered, and an oak screen with beaded decoration on its inner room side and an original Tudor-arched door separates the hall from the kitchen (originally the parlour). The fireplace was recently, since 1980, revealed as a lateral one on the rear wall, and the external chimney stack was presumably removed when the lean-to was constructed. The ceiling features stop-chamfered spine beams with run-out stops of the Wern-hir type. A similar beaded partition is found on the upper floor, but is now painted. A spiral firestair is present in the single-unit section, alongside a 4-centred oak door surround. The roofs are interconnected and are of a principal rafter type, with three tiers of trenched purlins and complete secondary rafters.
