Wing of Long Marston Hall, Now the Old Granary

The building known as the Wing of Long Marston Hall, now called The Old Granary, is a house dating from the late 17th century, with alterations from the 18th century and a conversion in the 20th century. It is constructed of red-brown brick and features a 20th-century pantile roof, along with stone quoins. The structure has two storeys and is arranged in a 2 x 3 bay format. The gable facing the road has two 20-pane sash windows on the ground floor and 16-pane sash windows above, all set in reduced openings. On the right side, there is a central blocked cambered-arched cart entrance that has been fitted with 20th-century double doors. The building also has 20th-century small-pane windows and a projecting band at the mid-first-floor window level.

This building is listed for its historical significance as a remnant of the late 17th-century southern wing of Long Marston Hall. It is believed that the property was divided into two separate homes in the 18th century, after which the wing was converted into a barn. The blocked gable windows, which once had eared ashlar architraves, likely resembled those that remain at Long Marston Hall and were depicted by Samuel Buck around 1723.
