A very simple protection cover for our AC. Its built entirely
on free wood I got from the lumber yard. They store stacks of
impregnated wood with small impregnated wood sticks in between. These
sticks are then thrown away, and I asked if I could have them. Even the
larger frame is from the scrap bin. The roof is just stick screwed on
top of each other. Looks a bit better than w/o.
