Main Mill Building at Bourne Mills

The main mill building at Bourne Mills is an early 19th-century structure located on the south side of London Road in Brimscombe. It is built from coursed rubble limestone and features an ashlar chimney and a diagonal asbestos slate roof. The building is four storeys tall, with a three-storey block at the south end, forming an L-shape.

On the west side, there are eight windows with two-light chamfered mullioned casements, many of which still have their original leading. An upper floor doorway once had a high-level timber walkway leading to a small mill building to the west. There are some alterations on the right side. The east side features eight segmental arched windows, all with leaded timber casements. The gabled ends have parapets, with the northern end displaying segmental arched doorways on each floor and a hoist gantry above. A cut-down gable-end chimney is also present.

The lower block at the south end has one corner that was cut off and rebuilt due to the construction of the adjacent Cheltenham and Great Western Union Railway in 1844. The interior has not been inspected. It is likely that the east wall of the mill was rebuilt around 1840, which accounts for the apparent difference in construction dates between the two main walls. The small mill building to the west and the canal bridge to the north are also noted.
