Our shed in back has seen better days. If we stay here, we'll probably end up replacing it at some point. However, today I screwed back on a panel of the sheet steel wall that blew out over the winter, removed both doors from the front (one had already been off the slider for some time) and installed a new door frame and assembled the skeleton for a new hinged door. I'm going to use the original doors as the "skin" of the hinged door so that everything matches. Total cost: less than $30.
