Whitecross House, including No 1 Powell Court and attached front railings

Whitecross House is a double-depth central entry plan house, originally dating from the early 18th century. It is three storeys high with five windows. The exterior is rendered and painted, with a Welsh slate roof. It features painted long and short chamfered quoins, keystones over the windows, and decorative band courses at floor levels. The front door has six raised-and-fielded panels and an interlace transom light, topped by a hood with heavy moulded brackets now supported on slim cast iron columns, forming a small porch. The windows are flush-framed sash windows; the ground and first floors have 6-over-6 panes, while the top floor has 3-over-6 panes. The roof is hipped, with tall chimney stacks on the right side wall, with one stack inset and one external to the left. Attached spearhead railings run along the front. The building has blind return walls and backs onto Holly House Powell's Court.

The rear elevation has been altered and extended, and its appearance is partially obscured. The interior demonstrates joinery from two periods: early 18th century features such as doors with butterfly hinges, cupboards, and a shell-headed cupboard with shaped shelves; and from the early 19th century including a stick baluster staircase with a mahogany handrail and 6-panel doors. While the staircase was partially replaced, it retains original 18th-century straight flights and a closed string. The rear layout shows alterations likely associated with its former use as a public house, including flagstone floors and a beer cellar that extends underneath the adjoining Holly House. Upstairs features include shutters, an alcove, old floorboards, and doors. The attic floor has no visible features.
