A coach house and two gateways built in 1735 from red brick in Flemish bond with ashlar dressings and has a hipped pantile roof with a single wooden ridge turret with a pyramidal lead roof. For the full description and the legal address of this listed building please refer to the appropriate List of Buildings of Special Architectural or Historic Interest. {1} The coach house is a detached, single storey building located on the north side of the Stable Courtyard. It is built out of handmade brick, laid in Flemish bond, and has a high ridged, pantile covered, hipped roof. The Coach House has a square timber turret vent with louvres that rises from the ridge line of the roof. There are short curved connecting walls, with single arched gates through them, that run from the Coach House to the Clock House to the southwest and the Stables to the south-east. The southern elevation is the principal façade of the building, and it has three sets of double doors at the centre, with single doors on either side. The double doors have rounded heads made of header bricks with a central keystone carved with WM and 1735. The doorways are big enough to allow access for large horses. The eastern elevation is plain, and is partially obscured by vegetation. The northern elevation faces onto an enclosed yard and garden area, which appears to be ancillary space away from the formality of the courtyard. The east end of the elevation has a wide doorway with a timber lintel. The west end of the elevation has a timber, mono-pitched extension built off of it. The western elevation of the Coach House has had a doorway inserted into it at a later date. The Coach House has 4 internal rooms, plus 2 additional rooms in the timber extension. The first room, at the western end of the building, contains evidence for wall mounted brackets that likely supported line shafting powered from the engine in the extension (this power drive would have operated belt driven machinery). This room is open to the rafters, although there is evidence for a loft or first floor as there is a brick blocked opening in the upper gable of the northern wall, which may have been a doorway. The next room over is the smallest room, which has a brick floor and is open to the rafters with further evidence for a loft (as seen in the blocked opening in the southern wall). There are two parallel lines of stone slabs in the floor, which is indicative of the original use as a cart or coach house, and would have prevented the iron rimmed wheels of the coaches from digging into the soft brick floor. At the start of the 20th century, the room was used to house batteries that were charged from the engine on the opposite side of the north wall. These were used to maintain a power supply to the main house at night or when the engine was off. The third room is the largest in the coach house, and is accessed via the three sets of double doors in the south wall. The interior arrangement has changed since 1735, when is functioned as a double coach house. The floor is cobbled and has two sets of two parallel rows of stone slabs. The slabs on the east side of the room have had a vehicle inspection pit dug between them, providing evidence for the switch from carriages to cars. In the early 20th century, a hand operated winch was installed to lift heavy parts, and electric lights were installed in the work area. The fourth room, at the eastern end of the building, is double stables. It is open to the rafters, and entry is via the large doorway in the south wall. The eastern portion of the room has been subdivided by a central timber stall, likely used for the larger horses that pulled the carriages. An unsual feature of the room is a rectangular piece of timber with chamfered sides and a central recess with a pointed head. This has been interpreted as a niche for a lamp or candle, which was used to light the stable. It is very ornate , considered to be a rare survival, and likely part of the original design of the Coach House. The final two rooms are in the timber extension off the northern elevation of the Coach House. The extension was built in the early part of the 20th century. It is built out of timber, with vertical timber plank cladding, and has a mono pitch roof covered with pantiles. It has 2 windows in the northern elevation. The first of the extension rooms is the sawmill. It has the remains of a saw bench, which survives along the north wall. Overhead metal belting wheels formed a power drive from the engine in the adjacent room. There is some evidence for a second power drive. The second room in the timeber extension is the engine room. It contains a centrally located engine, which generated power for the house. The engine was built by Robey and Co. Ltd. in Lincoln, and is an excellent example of a stationary open sided crank diesel engine. Each engine was tailor made dependent upon the requirements of the client, and had a unique number to ensure the correct parts were installed. The Gunby Hall engine is No. 44559, which was stamped on to a brass plate. It has a large fuel tank on top of the crank shaft, which would be topped up with diesel. The engine provided power to the batteries in room 2 of the Coach House. {2}
