It was built with multi-coloured stone in a square or rectangular shape, laid in irregular courses, and features Bath stone ashlar dressings and a Welsh slate roof. The building is designed in a restrained Gothic style and has a double depth central entry plan with a stair at the rear.
It stands two storeys tall and has three bays, with a single storey flanking wing that has a stepped parapet descending in height towards the right. The left-hand bay is narrower and has a 2-light window on both the first and ground floors, with the ground floor window being transomed. The central bay is gabled, featuring a chimney finial that rises through the centre of the gable. It has a 3-light mullioned window on the first floor, with a pointed relieving arch above a ground floor pointed doorway that has a dripstone. To the right of the doorway is a mullioned and transomed window.
The right end bay contains a 3-light mullioned window on the first floor, while the ground floor has a single light transomed window and a 2-light transomed window. The single storey wing to the right has a 3-light mullioned window and a stepped parapet. Each return at the base of the stack features a 2-light flat-headed mullioned window with a pointed arch above. The roof is steeply pitched with gable copings and end stacks.
The rear elevation includes a central stair window with 2-lights and two transoms, with a back door below.
