Number 23 and Attached Front Area Railings and Rear Garden Walls

Number 23 is a house, now used as an office, built between 1788 and 1791 by William Paty. The building features limestone ashlar and coursed Pennant rubble in the basement, with brick gable stacks and a slate double-pile roof. It has a double-depth plan and is designed in the mid-Georgian style. The house stands three storeys tall, with an attic, basement, and sub-basement, and has a symmetrical front with a rusticated ground floor, a plat band, a cornice, and a parapet.

The central doorway is flanked by pilasters leading to a Doric entablature with a pediment, and it features a semicircular arch with a metal fanlight and a six-panel door. The ground-floor windows have large keys and are 6/6-pane sashes, while the second-floor windows are smaller. There are two hipped dormers, and the right-hand return has a semicircular-arched stair light on the first floor. The rear elevation is similar to the front. The rubble basement includes segmental-arched Pennant lintels, and there are tall stacks separated by a semicircular arch.

Inside, there is a semicircular-arched doorway with a fanlight leading to a central stair hall. The right-hand open dogleg stair features a curtail, column-on-vase balusters, and a wreathed and ramped banded rail. There are paired semicircular-arched doorways from the hall and landing, along with cornices adorned with festoons, fireplaces, six-panel doors, and panelled shutters.

The property also includes attached cast-iron front area railings and gates that curve up to the door, as well as rear brick garden walls. Number 23 is one of several houses on the street that have matching fronts but different plans for various clients.
