20, St Andrewgate

No. 20 St Andrewgate is a house, now divided into flats, built around 1780. It was designed by architect Thomas Atkinson for his own use and underwent renovation with a new wing added in 1978. The front is made of pink-cream mottled brick laid in Flemish bond on a high stone plinth, featuring a stone doorcase and cornice, with vertically tooled stone dressings. The rear is constructed of red brick in stretcher bond. The roof is slate, coped with stone, and has brick stacks.

The building has two storeys and an attic, with a five-bay pedimented front. The central entrance features a rusticated doorcase with a moulded pediment on carved consoles, set within a shallow elliptical arched recess. The door has two incised and two sunk panels beneath a moulded fluted impost band, topped by an elliptical fanlight with wheatear glazing bars. The central first-floor window has a shaped architrave and a moulded cornice. The ground and first-floor windows are 12-pane sashes with slender glazing bars and stone sill bands, while the attic windows are 2- and 4-pane horizontal sliding sashes with stone sills. All windows, except for the central first-floor window, have segmental brick arches. The moulded cornice of the gable pediment features a cross-glazed oculus in a moulded surround, encircled by a carved festoon suspended from a scallop shell.

At the rear, there is a three-storey gable, with the left part obscured by the 20th-century wing. A segment-arched doorway is located in the centre, with a two-storey inserted bay window to the right. The bay windows are tripartite, and there is a round-arched staircase sash window above the doorway, along with a louvred roundel in the gable end.

The interior includes various simple contemporary fireplaces and two stone cantilevered staircases, with the main staircase featuring cast-iron balusters and a mahogany handrail.
