Erw-pwll-y-glo

Erw-pwll-y-glo is a largely 18th-century, two-storey, symmetrical three-bay farmhouse with single-storey ranges extending to either side. The main building is constructed of roughly coursed rubble stone, formerly rendered to the front and butter pointed to the rear, with slate hung to the left return. It has a hipped slate roof with a deep eaves soffit formed of painted slate slabs and rendered stacks on the left and right. The three-window front features unhorned twelve-pane sashes with slate sills. The central entrance has a 19th-century panelled door, originally from elsewhere, beneath a wreathed and radiating fanlight set in a narrow rectangular frame, all contained within a slate doorcase with panelled pilasters, consoles, and a flat hood. A single-storey, hip-roofed range on the left has a small rendered projection with a small window containing stained glass and margin lights, brought from a house in Welshpool. The single-storey range to the right features a glazed door on the left with a 20th-century rooflight immediately to the right, a nine-paned window, and an integral end stack. The rear wall of the main house has twelve-pane sashes (unhorned on the first floor) flanking a tall fifteen-pane staircase window; the lower right window replaces what was formerly a doorway.

The central hallway has a consoled arch at the foot of the original dog-leg staircase, which has a wreathed and moulded handrail and two stick balusters to each tread. Six-panel doors lead to the front rooms, while those to the rear rooms are plank doors with six panels applied to their outer faces. Panelled window shutters are also present. Painted slate fireplaces are found in two principal ground-floor rooms, featuring bracketed mantleshelves and cast-iron grates. The single-storey section to the right, formerly the kitchen, has a partly rebuilt open fireplace with a timber lintel and a bread oven on the left, with exposed thin joists to the ceiling and a loft above. One sash box removed from a ground-floor window in the main range bears the pencilled inscription "Owen Morris made this July 6 1831".
