Description

Botley (Flour) Mills is a flour mill built around 1770 that is still in operation. The front of the building features a nearly symmetrical design with two storeys and an attic, comprising three windows on either side of a central section that rises to three storeys and is topped with a brick dentilled pediment gable. The red tile roof includes a series of hipped roof dormers at both the front and rear, and a parapet with a decorative brick band below the coping. The walls are constructed of red brick in Flemish bond with blue headers, and the windows have red-rubbed cambered arches. There is a stone cill band at the first floor level. A wide arch on the east side serves as the carriage entrance, while another arch under the central section leads to the entrance door. The windows are casements. At the rear, the water level reaches the first floor, where there are three windows on either side of a central door. Inside, the building has a heavy timber frame and retains much of its old equipment. There is a rearward extension on the north side that is of similar age, and a tall modern structure from 1922 is attached to the south.
