Description
Denbigh House is a two-storey building with attics that features applied 'half-timbering', which may be covering an original timber-framed structure. It has a slate roof and a central red brick chimney. The building includes three dormers adorned with carved bargeboards and finials, along with small-pane casement glazing. On the first floor, there is a small-pane casement window beneath each dormer, and the mock timber-framing is applied here as well.
The ground floor has been extended forward with a flat-roofed shop extension made of red brick, which contains two late 19th-century shopfronts. Each shopfront features central double-leaf doors that are partly glazed, set back between shop windows. The ends of the shopfronts have classically derived pilasters with a fascia and cornice above.
At the rear, the elevation facing the churchyard has a rendered upper storey with applied 'half-timbering' and three small-pane casement windows. The brick ground floor has a door for each shop, two small-pane casement windows, and to the right, a larger window with six-pane horned sash glazing. Inside the shops, there is a longitudinal moulded beam supported by iron stanchions, which features spurious inscriptions reading '1501' and 'Powis'.
