Description

Wynn Hall is a house dating from the 17th century, although significantly altered and embellished in the 19th century. The external appearance is of timber framing, much of it concealed behind roughcast render, though some decorative framing is visible in the porch and dormer gables. Some walls are said to be brick or stone. The roof is slate, with 19th-century brick stacks topped with terracotta caps. It is arranged with a three-unit plan, featuring an off-centre axial stack and a baffle entrance housed within a wide, projecting gabled wing. This wing contains an entrance passage and a small room, and is distinguished by a whimsical timber-gabled porch with decorative paneling, turned supports, and a carved date of 1649, which is likely from the early 19th century. The gable apex features diagonal small-panelled framing with quatrefoil decoration, probably dating from the early 17th century. Similar decorative detailing is found in the dormer gables above the paired upper windows to the left of the porch and the single window to its right. Original windows throughout, except for a later rear addition, are small-paned, two-light casements with margin lights in heavy wood frames, with drop-ended hood moulds over the lower windows. A small two-light window, and timber 'lancet' lights are found in the return of the porch wing.

The central hall contains an axial fireplace with a plain timber bressumer. Much of the original decorative timber panelling was removed around 1970, but some remains. The staircase, likely inserted in its present position, is thought to be from the early 17th century, with turned balusters, square newels, acorn finials, and is notably steep. A study in the advanced gable has a fireplace with a decorative surround assembled from panelling in a 17th-century style. These features, along with the hall panelling and staircase, represent the surviving fragments of a once-richer decorative scheme, reminiscent of Plas Newydd, Llangollen. A second staircase, located at the rear of the hall and recessed behind a moulded plaster arch probably dating from the early 19th century (with a glazed lantern above), is also from the early 17th century and has turned balusters and square newels. A former front room's wall panelling was removed around 1970, exposing square panelled framing in the internal walls. A rear room features a plaster moulded cornice that encases and panels its transverse beam. The first floor layout has been altered, but the original roofline and the framing of the original rear wall remain visible, along with evidence of a later raising in height.
