There are several ways to economize when building a shed: Install three-tab roof shingles instead of architectural shingles, or use grooved-plywood siding in place of cedar bevel siding. But don't ever skimp on the building materials used for the floor frame or plywood floor deck. I can't tell you how often I've walked into a shed and found the floor to be dangerously spongy. One building in particular had a floor so badly rotted it felt like one of those inflatable moonwalk attractions you see at carnivals.

· Gable shed — they are also common due to their stylish two-faced roof that meets at the center forming a peak. Their roof shapes are conducive as they provide adequate space, but not as much as the gambrel styled sheds. They provide adequate spaces for storage of garden tools. They also accommodate larger items as motorcycles. The property that makes these sheds become common is their stylish shape that blends in well with any compound with a house of any design.
There are many types of roof design that you can use to add to your shed. But since you are a beginner, I would advise you to build a simple roof structure so as to avoid the frustrations that can come with building complex roof structures. Complex roof structures also require additional tools and greats skills hence, it is time consuming and a bit expensive compared to the simple roof structure.
We now need to create a base that we can nail the frames for the walls into.  We did this with four 2x8's and some bent i-bolts along with a lot of mortar.  The basic process was that we bent the bottoms of the i-bolts after heating them with a blow torch, and then anchored these in some of the holes in the cinderblocks with a lot of mortar.  Then we drilled holes in the 2x8's where the i-bolts were and put these on top and screwed them in.  The frames can now be solidly attached to the base with the framing hammer.
Don’t be tempted to get sloppy when you square up the floor and walls of your shed. An out-of-square start will haunt you through the rest of the project, from doors and windows to trim and roofing. For a concrete slab, measure diagonally across the opposite corners of the form boards. Then adjust the forms until the diagonal measurements are equal. Do the same for a wood platform floor. If you’re installing sheet siding on the walls, before you stand them up, measure diagonally and square up the wall before you nail on the siding.
I think that we had to purchase some additional hangers that were built especially for bike tires. This system worked pretty well, one comment that I have is that they don't hold up to the weight of several combined bikes as well as I would like. You need to make sure that the track is anchored very often, as having hooks in between anchor points starts to flex the main rail and can result in the hooks popping off.

I'm always surprised at how little forethought most backyard builders give to the shed's doors. After all, there's no sense in building a shed to store a particular item, such as a lawn tractor or wheelbarrow, if you can't fit it through the door. I saw a shed recently that had its doors removed. When I asked why, the homeowner explained that he framed the doorway wide enough for his riding lawnmower, but didn't take into account the amount of space taken up by the hinged inset doors. So, he had to remove the doors to fit the mower inside. (He's in the market for a skinnier mower.)
Level the ground (if necessary) and install deck piers along a grid to support the shed. The piers will allow you to string support beams beneath the floor of the shed. In the example design, the piers are spaced 6 feet (1.8 m) apart in one direction and 4 feet (1.2 m) apart in the other for a total grid area of 12 x 8 feet. This is convenient because once you lay supports along this grid, it will take exactly three standard 4- by 8-foot plywood sheets to cover it.[1]
There are a lot of plans and designs to choose from when building the shed, so make sure you take a look over several alternatives before starting the actual construction. Invest in weather-resistant lumber (pressure-treated lumber), making sure all the components are in a good condition and perfectly straight. Drill pilot holes before inserting the screws, to prevent the wood from splitting.
The best spot for a shed is level, well-drained ground close to where you work in your garden or yard. The location doesn’t need to be perfectly flat; the foundation design shown in the plans allows for adjustments to make the floor level. Small sheds require only a top-of-soil foundation, even in locations with freezing winter temperatures. Precast concrete deck blocks work perfectly for this.
