Former Root Shed, Leighton Farm

The Former Root Shed at Leighton Farm is a Grade II* listed building consisting of two parallel single-storey ranges with vaulted tunnels beneath. It features a brick structure built on a random rubble basement, with a roof that has slate on the outer pitches, corrugated asbestos-cement, and glazed panels on the inner pitches. The gables are coped and supported by moulded kneelers.

The southern gable ends face the road and are characterized by wide round-headed doorways, with the right doorway being lowered. These doorways originally had vertical sliding gates, which are now in front of inserted sliding doors. The eastern side wall includes breathers arranged in lozenge patterns, along with an inserted door at the southern end. The northern gable ends also feature breathers in lozenge patterns. Beneath the random rubble basement wall, there are openings leading to six brick-vaulted tunnels, although one tunnel is now concealed by an inserted door.

Inside, a row of central posts has been infilled with concrete blocks, dividing the space into two units. The western range has a roof supported by king and queen posts and raking struts. The eastern range is noted to have a sloping cartway. The western range has a modern concrete floor, but the shafts used for passing roots can still be seen in the vaulted tunnels of the basement.
