Thanks for replies to prev post.
The dividing wall from neighbour faces south and is 6 feet high. And this wall would form one side of the shed I like the idea of; say 24" long frames accommodating 6" high panes of security glass sitting along the dividing wall. This would provide good light (as they face south) into the interior and raise the shed ceiling height to 7 - 7.5'. Then perhaps a similair narrow window near the top of one of the other walls.
I should get permission from the neighbour !!??
