Let's have a look: Cheapest Home Depot Shed[1]: $800 ($649 +$250 delivery) Windows[2]: $210 (3x$70) Wall Insulation (shed walls are ~10x10): $113.50 ($11.35 for a 40 ft^2 roll of minimum R13 batt) Ceiling Insulation (approximating @100ft^2)[3]: $118.28 (2x$59.14) Actual Door[4]: $99 Drywall[5]: $84.80 (approx. 10 peices) Total: $1524.58 Looks like you're correct, it could be cheaper. Wait a minute, we just have a pile of materials now. Let's put it together. Judging by [6], it's about $1500 of labor to hire a professional to build you a shed. Let's assume that you can negotiate installation of the insulation, drywall, and windows for free (it's for a good cause!). You are now at $3,024.58 final cost. Hmm.
