Thank you Wes and Bonniebeth.
It looks great!
Is there a way for the wall to be opened so you can get into the roofed in area?
The stairs keep the door from being operable which is just as well, that first step would be a killer and I wouldn't want the Trolley's falling down the stairs.

You could put it on the other side of the house and avoid the stairs all together.
