Small Shed Design – Objective
Learn how to design and build your own small shed with this free and easy to use plans. It is a perfect storage shed for a lawn mower and other gardening equipment.
Designing the Shed
The size of the shed is determined by what it will house. If it will only hold a small push mower and maybe a handful of other tools, then it need not be very large at all. The only reason for building a shed with more space than needed is if you are planning to have something else in the future for it to hold. A shed built far larger than necessary is no more than a waste of effort, space, and money. For our purpose, we will consider making the shed 4 x 8. The way to determine how big to make your shed is simple. Lay out a mock shed on the ground with some sort of marking material (rope, extension cord). Be sure to make door opening and practice loading and unloading the shed until you are satisfied with the size of the building and the size of the door.
Post frame construction is the easiest, cheapest, and strongest method for building a small storage shed. for gardening purposes, a floor is simply not necessary. Using the ground for the floor eliminates any need for a shed ramp and cuts down on the cost of the project considerably.
Building the Shed
Lay out for the four post holes just like on post hole lay out. The posts will form a rectangle 93″ x 45″. With this 4 x 8 design the door is one complete end. By the way, this shed is aimed at holding a medium size garden tiller, a push mower, and various other gardening tools such as shovels, rakes, and hoes. Dig the post holes 24″ deep and set the 4 x 4 x 10 posts with two braces on each one. Plumb the posts and nail the braces to 2 x 4 stakes in the ground. Put the braces on the inside and keep them well away from the outside perimeter. Pour premixed concrete in the holes and let the posts set at least overnight.
One of the 8′ walls will be the high shed wall and the other one will be the low shed wall. This super simple construction style needs no ceiling joist and uses simple rafters with no birds mouth or overhang. Determine the high shed wall. Make it as tall as possible. The low shed wall needs to be at least one inch lower, but four inches is preferred. Nail on 2 x 6 roof beams and saw off the posts. Use simple square rafters nailed to the inside of the roof beams and flush with the top. Put them on 24″ center. Top them with 1 x 4’s running perpendicular and on 24″ centers. From the top of the high shed wall roof beam, lay out the posts for 2 x 4 wall girts. 24″ center is good for T111 siding. Nail on the wall girts. Be sure to fill in around the edges on the end where the door will be.
