For example, the last three sheds I built were trimmed with white PVC trim boards instead of painted cedar 1 x 4s. This new plastic lumber, which I used for the rake, fascia, frieze and corner boards, is impervious to bugs, warping, splitting or decay, and it never needs painting. Other low-maintenance options include: vinyl or aluminum windows, faux-slate roof shingles, fiberglass or steel doors, composite decking for steps, and fiber-cement siding. (I don't usually recommend aluminum or vinyl siding for sheds; neither material is rugged enough to survive the inevitable beating outbuildings take.)
The ad shows the bright shiny new 8x12 Gabled Shed. However, after purchase, that plan does not show up anywhere. I have emailed and requested that plan several times but no response. So, thanks to those who have already posted the 1-800-390-6035 number for ClickBank customer support. It's a chore to work with their VRU but with patience, you can get a refund.

For the shed's floor deck, use ¾-in. exterior-grade plywood; anything thinner will flex between joists. (Note that a double layer of ½-in. exterior ply is okay, too.) If you plan to store heavy items, such as a lawn tractor or woodworking machines, consider using ¾-in. tongue-and-groove plywood. This costs slightly more, and is a bit more troublesome to install, but its edges lock tightly together, creating a rock-solid, rigid floor. In areas with excessively high moisture and large numbers of wood-boring bugs--such as Florida, Alabama and the other Gulf Coast states--consider using pressure-treated plywood for the floor deck. It's particularly resistant to moisture and insects.

The roof truss can be built using 2x4 or 2x6 lumbers. There are different ways to build the truss, the most common is cutting out the rafters and assembling them using gussets. The easiest way to build the roof truss will be using plans. The other option will be to lay the 2x4’s or 2x6’s on the level floor set them how you want your roof and make a template. Once you are happy with the look of your template you can build the rest.
You can build the walls on any flat surface, but the shed platform is ideal. Snap chalk lines on the plywood deck, 3-1/2 in. from the edges of the platform, to indicate the inside edge of the walls. Measure to make sure the lines are parallel and 89 in. apart. Then chalk a line down the center (Photo 1). You’ll use this line to make sure the angled top plates meet in the center.
Build the framework for the back wall. Make the top and bottom beams (a.k.a. the plates) the same length as the length of the floor which they sit. To keep your measurements simple, make the spacing between the vertical studs identical to the spacing between your floor joists. Note that the back wall should be lower than the front wall so that the roof slopes and directs rain away from the door.[6]
Working from ladders is more dangerous than working from scaffolding. Plus, having to constantly move ladders around is time consuming. When you get to the roof construction, consider renting a set of scaffolding with wheels. You’ll be amazed at how much easier it is to have a stable platform to work from and to set your tools and materials on. You can rent a 5-ft.-tall section of scaffold with three planks and wheels for about $110 per week.
