Description

This building is a late Georgian surgery, featuring three stories and a three-window front made of cement render. The facade includes rusticated long and short work quoins and an advanced giant arch in the central bay, with similar detailing at the angles. The hipped slate roof has wide eaves and a brick stack on the right. Each floor has later two-light sash windows with rusticated surrounds and voussoir lintels. The porch has a flat bracketed hood and a recessed six-panel door beneath a five-pane fanlight. The left side elevation is simply cement rendered.

There are modern extensions to the right that are not of special interest.

To the northwest, there is a contemporary three-sided single-storey and attic courtyard that was formerly used as stables and is open to the street side. It has rendered rubble walls, slate roofs, and a brick stack. The northwest range features a plain rubble gable end with a boarded loft door on the inner side, which retains the original roof construction of overlapping purlins.

In front of the garden, there is a rubble boundary wall that marks the site of the original almshouses.
