This is a very well designed light weight structure.  It's easy enough for a small lady to build.  The roof, and main door gable were big challenges.  I would have color codeed the tubing for the two doors since they were different.  Instructions are complicated.  Tool parts are labelled, if the little plastic bags could also note where they were designated, that would eliminate guessing in the process (i.e. roof parts, windows parts...etc).

I had put some netting around my wood foundation to prevent uninvited critters.
