Brook Mill consists of a group of silk throwing and weaving mills, water- and later steam-powered, dating from 1785 with extensions in the early 19th century and a significant addition in 1835. The complex is constructed of brick with stone foundation courses, and has slate roofs. The plan is irregular, following the water course, with the two original four-story mills and a five-story weaving mill added in 1835 at an angle to the east. Ancillary buildings are located in the yard to the south.

The main block is four to five stories high, with a window range of 4:9:9 for the earlier section and 8 for the 1835 eastern range. The earlier mills are lower and narrower, with stone lintels. The western section features a four-window width and a stair tower at the end, while the wider mill to the west has a lavatory tower on the south side. The two earlier mills are slightly canted to one another. The 1835 mill displays dated rainwater hoppers, a parapet, coped gables, and rubbed brick flat arches. A half-round dry shute privy tower, with small openings to each floor and an open ashlar base, is located on the left-hand gable of the western section; a round stair tower formerly attached to the eastern gable has since been demolished. Interior features of the earlier mills include timber cross beams and king and queen post roofs, while the 1835 mill features two rows of cast-iron columns supporting box beam floors.

Attached iron spear-headed railings run along the northern wall bordering the stream, and a former yard wall with an ashlar base extends along the western side, following the stream, and returning towards the south.

Originally built for throwing and weaving silk, the mill used both water and steam power by 1821. The 1835 mill was specifically for powered weaving, and the privy shute is a well-preserved example of advancements in mill worker amenities. From 1835, the complex was adapted for silk spinning, with dressing and spinning occurring on the ground floors and weaving on the upper floors. Brook Mill represents the largest surviving complex of silk mills in Congleton and the only remaining example of a silk spinning works in the region. It is a site of considerable historical interest, illustrating how even modest water power sites could be exploited and the increasing scale of mills from the late 18th to mid-19th century.
