The Ralph Allen Town House

The Ralph Allen Town House is a significant building that was part of Ralph Allen's former town house, constructed in 1727, with possible earlier origins. It showcases a highly decorative Palladian style, which is attributed to John Wood the Elder.

The building is made of limestone ashlar and features a pantile roof. It is designed as a single depth extension, square in plan, situated behind an elaborate facade.

The exterior presents an opulent three-storey, three-bay front with a Classical order of giant Corinthian half columns above a rusticated basement. Originally, the basement served as an open loggia leading to Ralph Allen's garden, but it has since been filled in. The central arched opening features a keystone and a nine over nine pane sash window, flanked by narrow flat-headed keyed openings with four over six sashes. The first floor is designed as a Serliana, with openings separated by giant columns, and includes a large central sash window with thirty over twenty-four panes and a radiating fan head, flanked by narrow six over six sash windows with balustraded aprons. The upper floor has a six over six sash window flanked by four over four sashes, with relief swags on the outer aprons. The pediment features an oculus surrounded by elaborate wreathing, and balls on blocks at the apexes instead of acroteria. The roof has ridge stacks with pots.

The interior has not been inspected but is believed to have undergone significant alterations. It is known to contain a large 16th-century fireplace with a four-centred arch in the basement.
