Good day, our house came with a shed on the property that needs a new door. Previous owners put an interior door on the shed which has fallen apart. The frame is also rotted. It's a non standard size so I am trying to decide what to do. Rough opening is 34-3/8 x 77-1/8. I'm thinking it will be cheaper to just make my own door out of siding and some lumber. To do that, I'll probably need to build some kind of door frame. Pressure treated for that frame or no? Tips or things I may not be aware of?

Hi, I have a lot of recycled blue stone treads (18" x 1 1/2' x between 3' and 7'). Unfortunately, they still have a lot of concrete stuck to them as they came from a pool that was being renovated. To chisel off the concrete would, I imagine be an enormous and time consuming effort even though I have air powered chisels. Could I have these treads set on gravel or sand or concrete or a combination thereof, and keep them in place by edging them in concrete? Or would it be more economical (especially if I have to pay my mason to chisel of the concrete) to just buy new clean treads? My thanks in advance for your advice and help.
