Description

Y Berllan is a 2-storey, T-plan building with a longer east-west range attached to the south, running parallel to the T-plan’s east-west range. The construction is of roughly coursed rubblestone, with some parts roughcast, and it has a slate roof characterised by deep verges and carved purlin ends. The east front features a 3-light 24-paned casement window on the ground floor of a projecting gable, and a 2-light 16-paned casement above, both with voussoirs to slightly cambered heads. To the left of these is a 2-light 12-paned window and a 4-panel door, the top panels glazed, sheltered by an open lean-to porch set in the angle of a gable. The south front of the long east-west range has an entrance to the far left, immediately followed by a 2-light 12-paned casement window. Directly above this window is another in a gabled dormer that breaks the eaves. A tall 2-light 12-paned window is positioned to the right, likely illuminating a staircase. Prominent chimney stacks are a key architectural feature; those on the west wall of the long east-west range and the south wall of the north-south range are integral with stone bases and paired diagonal purple brick shafts. Similar lateral stacks are on the north side of the shorter east-west range, the western stack having a brick base and a single tall diagonal brick shaft. A single-storey lean-to brick outbuilding is attached to the north-west corner of this range, with a boundary wall attached to its south side that screens the gable end of the long east-west range. The interior was not inspected at the time of survey. Y Berllan forms part of a group of two buildings.
