Stable block and coach house approximately 12 metres to south west of Whitton Hall

The stable block and coach house, built around 1756, is approximately 12 metres south west of Whitton Hall. It represents a remodelling of a 17th-century building, although it has undergone some 20th-century alterations. The structure primarily comprises red brick with a timber-framed core, and is topped with a plain tile roof. It consists of five bays and has a single storey with an attic.

The north west elevation features a high plinth, a toothed brick eaves cornice, and parapeted gable ends. A prominent central octagonal wooden cupola rises above, displaying round-arched openings framed by impost blocks and keystones. It has a large square base and an ogee lead cap topped with a wrought iron weathervane, reportedly inscribed "I.T., Esq., 1756," likely the initials of John Topp II.

The north east front has six segmental-headed blind windows, with the left-hand one painted to imitate stonework. Some 20th-century wooden casements have been inserted. A wooden forecourt gate post and gate are attached to the left, featuring square posts with chamfered corners and moulded tops. The left-hand corner is chamfered upwards to the attic level. The left-hand gable end incorporates a wooden two-light attic casement and a pair of large boarded coach house doors with a segmental head. A stone mounting block is attached to the right. The rear of the building has been partially rebuilt in the 20th century, and includes a boarded loft door, two pairs of large boarded doors (the left-hand one a 20th-century sliding door and the right-hand with a depressed-arched head), and various small segmental-headed casements and boarded doors.

Internally, remnants of the original 17th-century timber-framed structure remain, including framed wall sections between bays, along with post and brace elements and a collar and cambered tie-beam roof with queen and V-struts. A truss between bays incorporates honeycomb brickwork, likely indicating it was once an external gable end. Pairs of staggered purlins are also visible in the roof structure. Straight joints in the gable end to the north west and a joint in the south west front suggest that the north east and south east walls were rebuilt before the rest of the building. The framing suggests the building was originally a barn; the nearby 18th-century barn to the west incorporates reused timbers that may have originated from this structure.

The stable block forms the south-west side of the forecourt to Whitton Hall and stands opposite the former service block.
