Seapy - nicely shot, and very similar in structure, tho' not shape, to my one. Mine was in a corner of the roof-space, and filled the corner completely - about 20-24" wide, almost 36" deep, 18" high at the front tapering to about 6" at the back of the space (under the timber lining of the roof). It was truly massive and the debris filled two large black bin-bags.
