Former Root Shed, Leighton Farm

Consisting of 2 parallel single-storey ranges with vaulted tunnels beneath. Brick on a random rubble basement, with roof of slate on the outer pitches, corrugated asbestos-cement and glazed panels on the inner pitches, and with coped gables on moulded kneelers. The S gable ends face the road and have wide round-headed doorways (the doorway to R lowered) with raised original vertical sliding gates in front of inserted sliding doors. The E side wall has breathers in lozenge patterns (and inserted door at S end). The N gable ends also have breathers in lozenge patterns. In the random rubble basement wall beneath are openings to 6 brick-vaulted tunnels (one now concealed by an inserted door).

A row of central posts is now infilled with concrete blocks, dividing the interior into 2 units. The W range has a roof with king and queen posts and raking struts. The E range is said to have a sloping cartway. The W range has a modern concrete floor but the shafts through which the roots were passed can be seen in the vaulted tunnels of the basement.
