ok here goes:
The top is stuff you can buy cut to size at B&Q/Homebase, and you can also buy the white trim to finish the edges. The hole has been drilled so that I can stick in a bamboo cane to stop the lid blowing shut (sophisticated !!) - I am sure there are lots more things you coud do to allow it to be open half way. I have been very happy with my two options (ie open/shut !).
As I said, it is now in about its tenth season, and still going strong.
Hope this helps - shout if you need anything photo'ed closer up.
