Sheds have become multipurpose, must-have buildings that are competing with pergolas and gazebos as your next backyard project. Pictures on social media only grab people's desires more. Before going any further, do your research. Figure out what you need it for and why, and whether you will build the shed yourself, or hire a pro. Check with your local planning department to comply with codes and guidelines. Determine if the shed will mirror the architectural features of your home--always a good idea. Assess your budget, materials needed, and the time it will take to complete the project.

If you have a router, use a hinge-mortising bit (or straight bit) to cut the hinge recesses (Photo 10). Otherwise, use a sharp chisel. Screw the hinges to the door and trim. To hang the door, line up a temporary 2×4 with the bottom of the siding and screw it to the wall. Then rest the door on the 2×4 and drive 3-in. screws through the trim into the framing to hold the door in place (Photo 11). Finish the door installation by adding the top and side trim pieces.
Now we can actually start building!  Before you start putting down cinderblocks, lay limestone screening down in all of the channels and run and burry your electrical.  Make sure that your electrical wires are clearly marked (we used caution tape) so that nobody digs them up accidentally in the future.  Once your all set, you can start putting down some cinderblocks.  You may need to break some cinderblocks in half, and this is easily done with a chisel, a hammer, and a bit of time.  Tip:  Set Rebar posts in each corner and tie strings across to help you keep the walls straight.  You need to check every single block for level, especially on this layer as the base of the foundation will affect the rest of the foundation and in turn affect the main structure.
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.
