Maes-yr-Helmau Farmhouse

Maes-yr-Helmau Farmhouse is an early 17th-century, two-unit cross-passage house with an end chimney, featuring a hall and two service rooms. It is located downhill, adjacent to a similarly dated farm building on the left.

The farmhouse is a single storey with a loft, constructed from whitewashed rubble masonry. It has a steeply pitched slate roof with plain eaves and close verges. To the right, there is a square stone end stack with water tabling, and to the left, a late 19th-century stock brick stack. The roof features three late 19th-century gabled dormers that are fully integrated into the roof structure, complete with bargeboards and slate-hung cheeks. The windows include two-light, small-paned casements, and there is an enlarged modern window on the ground floor to the left. The doorway, located to the left of center, has a stone lintel and a 19th-century plank door. To the right of the doorway, there is a small original window with a stone lintel and a two-pane fixed light window, as well as a blocked window at the extreme right.

On the rear elevation, there is a deepened window to the right with a stone lintel and a four-pane casement. A blocked door from the former cross-passage has a modern window inset to the right of center, also with a stone lintel. There is another deepened window to the left with a stone lintel and a four-pane casement, along with an enlarged window to the left featuring a timber lintel and a two-light small-paned casement.

Inside, the broad former cross-passage includes a raised cruck truss on the left, with the collar removed, and evidence of wattle infill. The ceiling features hollow stop-chamfered transverse beams, with the end beams resting against the walls. The cross-passage beams have ogee stops, while some joists are stop-chamfered, although the hall joists appear plain, suggesting a possible inserted ceiling. There is a stop-chamfered bressumer above the broad fireplace. A staircase dating from around 1800 leads to the loft, which contains two additional collared trusses, including a high yoke-like collar between the cruck and the chimney end. The hall seems to have remained unlofted beyond the cross-passage.
