Berllan-deg

Berllan-deg is a farmhouse, originally dating to the 17th century and altered in later centuries. It is constructed of wholly painted local rubblestone with Welsh slate roofs and rebuilt stacks in grey engineering brick. The house follows a three-room cross-passage plan, with the parlour being larger than the hall and a taller chamber block alongside a lower, in-line service range. This arrangement may suggest a detached kitchen originally, though there is no remaining evidence of this. The building now incorporates an attic space above the chambers.

The front elevation features the chamber block on the left and the service end on the right, with four windows across the facade. The centre is occupied by the cross-passage entry. The left side has four-light mullioned windows on the ground floor and three-light windows above, all with leaded lattice and moulded timber frames under angled dripstones. To the right is a single similar window on the ground floor, but the lower one is larger, modern, and without a dripstone. There is also an unleaded, additional two-light window on each floor. A modern ashlar 'Tudor' door is set under a dripstone. The roof to the left end is very steeply pitched, while the lower service end has a more moderate slope, with two Velux roof-lights on each roof. The left gable has a small stair window, and the roof features paired gable stacks with diamond-set shafts renewed in brick.

The rear elevation mirrors the front, retaining original ovolo-moulded mullions: four-light windows below and three-light windows above. A lean-to porch and utility room, built in the late 20th century, obscures the cross-passage entry, though it replicates the appearance of a previous structure noted in historical records. To the left of the porch is a two-light window below and a three-light window above. A plain 17th-century doorway with a plank door has been transferred from its original location in the cross-passage. Rooflights, replacements of earlier features, are present on each roof.

The interior includes a cross-passage doorway with roll-and-hollow moulding that has been moved to a service room. A stone ashlar doorway with a four-centred head leads from the cross-passage into the hall. A post-and-panel partition between the parlour and hall displays early painted decoration: a large interlace of yellow ribbons in a diamond pattern, which was once concealed. Plainly chamfered ceiling joists feature lambs' tongue stops. The larger parlour indicates a shift towards more private living arrangements, separating the family from the servants. There are two spiral staircases; one, with paired ornate shaped door-heads on the upper floor, confirms the house’s uniform date of construction, and the other, located within the parlour, has solid oak treads and rises to the attic. The roof structure includes two large principal rafter trusses with notched scarfed collars and trenched purlins.
