Llandyfan House

Llandyfan House is a farmhouse built from rubble stone, featuring a stone tile roof and stone end-wall and ridge stacks that project outward. The house has two storeys and an attic, with a raised plinth and an irregular three-window range. The windows are horned sashes, unusually with 5 over 5 panes. On the first floor, three sashes are roughly evenly spaced, while the ground floor has one sash on the extreme left, followed by a mid-Victorian stone porch aligned with the first window above. Next is a sash aligned with the centre window, but the last sash is set inward of the third window above. Further to the right, there is a door with a brick head, which may have been added later. The windows feature stone voussoirs below and oak lintels above, with a drip mould of stone tiles over the centre first-floor window.

The porch is made of squared red sandstone, similar to that of a nearby church, and has a pointed arch with bargeboards. Inside the porch is a half-glazed door. The south end wall has a large projecting stone stack with a square shaft and offsets on both sides. There is one first-floor 4-pane window to the right of the stack, above a stone-tiled lean-to. The north end stack also projects, with a large offset to the left and a smaller offset to the right. There is a 4-pane sash to the left of the stack with a timber lintel and an attic casement above it. The ground floor features a window with a stone lintel. The north end of the lean-to has a ground floor 8-pane fixed light and a three-pane window above, both with slab lintels.

At the rear, there is a lean-to that is also stone-tiled and includes a window, door, and two additional windows. Inside, the house has stone-flagged floors and original fireplaces with new oak bressumers. The ceilings feature chamfered beams throughout, and the wood door lintels also have chamfers, along with original oak plank doors. There is a reclaimed oak staircase and roof trusses, with one dairy slab remaining in the rear lean-to.
