I’m an electronics engineer, and being the engineering type, I build my own structures. I had been wanting to build a shed a couple of years ago, but OSB had gotten up to $18 a sheet (stuff I use on the exterior walls under the siding and for roof sheathing). A few years before that, a 4′ x 8′ sheet of OSB was only $6 a sheet. Knowing previous pricing, I couldn’t stomach spending the additional $10 per sheet and figured that if housing crashed, prices would drop. I waited and now OSB in my area is back down to $7 – $8 a sheet. Studs have also come down. Shingles are still a bit high, but I guess they may be affected more by oil pricing. I built my shed (16′ x 30′) a month ago and saved a bundle for waiting. I think I used 42 sheets of OSB in the structure, not counting the tongue and groove plywood for the floor (which had also dropped in price). I saved over half of what it would have cost to build the shed two years ago.
P.S. My friends call it the super shed, because it is so large. But I use it as a shed, so, to me, it is a shed.
