Enclosing Side Return?

[sallyfran]

We live in a typical ED terraced house with side return. We'd like to put a glass roof over part of the alley and a glass wall with door at the end, to create a workshop accessible to power and water (no room in garden). We're not looking to knock any walls down, just to enclose some space, but don't want it looking too much like a really rough lean-to as it will be visible from the kitchen, living room and garden. Has anybody done something similar. Any advice/recommendations?

Is it just me or does this thread sound rude?

Would be interested on the cost of this?
