Ggirl - B&Q (and i'm sure all the others too) will cut polycarbonate to order - so if you have timber you want to use that is a certain size, then you can make the lid to match. you can get slide on edging strips for it too, to finish it off. mr Chicky made mine about 10 years ago and it is still going strong. He sized it to fit round three of the black plastic trays they sell in GCs - since that was the only thing he couldn't customise.
they are wonderful things
