Tore down our old DIY hardwood shed and assembled a new plastic resin shed. Used an existing wood frame from the old shed as the foundation. Wrapped the foundation in a heavy duty tarp to protect against moisture. Stays dry, critters aren’t interested in living in it, looks ok.
Having assembled a plastic shed, I think it might be easier to build from scratch!
You’re spot on! If this thing fails, everything inside just gets covered with a tarp. HOA be damned.
