Cockloft

A cockloft is a horizontal void between a building's uppermost ceiling and its roof, with no habitable space.They are typically of combustible construction, with limited or no access. They may create a large space over multiple occupancies or adjoining buildings. They are commonly present in North America in older commercial buildings and rowhouses, with the roof above sloping from front to back, creating a shallow attic-like space.[1][2][3]

Cocklofts have particular significance in firefighting, since they are difficult to access, are unlighted, require stooping or crawling, with no walkable floors, and are typically constructed with exposed lumber. Fire may remain active and undetected in such spaces, and may flash over when oxygen is introduced by ventilation.[2][4][5]
