We bought a shed from Home Depot that we assembled to store my fabrics in when my daughter and 3 granddaughters moved in with us. At that time I had to sew on the kitchen table and go out to the shed to get fabric or patterns. We had no trouble with leaks or any weather damage for the 8 years they lived with us. I had two of my neighbors get a shed built for them. It would be a good idea to have one built and then you could customize it the way you want to your specifications. Now I have two extra bedrooms to put all of my sewing things in and it is great. Good luck on your decision
