I don't have one, I live alone so my whole house is my "she-shed"....
But a dear friend got a two story shed from Home Depot. The only thing it doesn't have is running water ie: no toilet. She got it it about 10 years ago and the steep narrow staircase to the upstairs bedroom was fine then. As she and her husband aged, the knees and her overall health became a problem and it is extremely difficult to climb those stairs now. Granted, not everyone will develop bad knees but stair climbing is something to consider as you age.
She loves it and has it set up with her embroidery business as well as all quilting/sewing things.
Good luck with yours.
