Ray says maybe the hardware cloth.... or the wood... under the steel roof we also have plywood. so, yeah. hard to say.Well, the run is basically Cinder blocks, 2x4's, 2x6's, metal roof, and hardware cloth. I really didn't keep track of price too much? I'd say though the lumber was the most expensive as the hardware cloth is all sandwiched between 2- 2x4's or a 2x4 and a 2x6. Try to buy the lumber onsale... next would be the 1/2"hardware cloth, that stuff is pretty spendy, also get that onsale. The metal roofing wasn't bad.
It all adds up though!
(I'll ask my husband when he gets home what he remembers was most spendy, he may have a better memory of it than me, I just wanted what I wanted, lol)
