After tearing down our very old 10 X 20 shed we decided to build a new one. It was just going to another shed. However, after a few minor changes to our plans it became a 12 X 20 building of multiple uses. The bottom will be used as a shop/garage with air conditioning and heat, the upstairs with a full 36 X 80 door put in on its side with weights inside to make it self opening will be used for storage and a play room for our grandchildren. The Ryobi cordless drill and impact made this job so much easier without lugging around the extension cords.
