Former stable block to north-east of Matson House

The former stable block located to the north-east of Matson House is a Grade II listed building, dating from the late 18th century and originally built for George Augustus Selwyn. This structure served as servants' cottages in the stable yard of Matson House and was later repurposed as a school building within the grounds of Selwyn School.

The building is constructed of dressed stone in courses and brick, featuring a gabled roof made of tile and stone slate, along with a brick stack. It has an L-shaped plan, with the longer east range originally serving as stables and the shorter north range consisting of two cottages, enclosing the north corner of the service yard behind Matson House.

The exterior consists of two storeys, with the front elevations facing the courtyard designed in a late 16th-century style, likely incorporating reused features from the demolished manor house. Notable elements include a moulded string course at the parapet level and a coped parapet. At the north end of the east range, there is a large carriageway entry with a segmental arch. To the right of the archway on the ground floor, there is a doorway with a Tudor arched head and eared hoodmould, flanked by two two-light stone-framed and mullioned casements, each with hoodmoulds. The first floor features three similar casements.

On the front of the north range, the cottage on the right side has a doorway with a Tudor-arched head and hoodmould to the right, along with a two-light stone-framed mullioned casement to the left. The first floor contains two similar casements. The cottage on the left has a comparable design, but the doorway and window on the ground floor are raised to a higher level, and the first-floor windows are blind. The gable-end wall of this range is made of brick, with the gable rebuilt in brick and a late 20th-century window.

The interior of the building has not been inspected. The structure incorporates materials from the former manor house of the Robins family in Matson, which was purchased by Selwyn from the Dean and Chapter of Gloucester Cathedral in 1766 and subsequently demolished.
