12x18 Garden Shed Overview

Serious gardeners who want a spacious, durable, and convenient storage facility in their backyard will find this 12 x 18 garden shed very useful. The shed offers 216 square feet of floor space for storing all gardening and landscaping tools and equipment. With its spacious interior, it is ideally suited for lawnmowers, tractors, wheelbarrows, power tools, bicycles, and all sorts of landscaping gear. 9′ 9″ tall siding walls complement the spacious interior while offering sufficient height for long-handled items like shovels and rakes.

The shed comes with a 64-inch wide door which allows you to move tools and machines in and out with ease.

The shed is also suited for multiple purposes thanks to its sturdy construction and functional design. You can use it as a home office, a tiny house, a workshop, or a studio. It is outfitted with square windows with 3 feet 4 inches sides that let plenty of natural light in, so you won’t struggle to locate items inside.

The lean-to roof allows water to run off, minimizing the interior’s chances of dampness and looks great in most settings. You can even paint or stain the siding walls to your liking and add beauty to your property.

A nice set of plans to give us an idea… A nice set of plans to give us an idea of what it costs to build on site vs buying a prefab structure, and the quality differences between them. This set of plans is "bomb proof" according to my local lumberyard guy. 2x6 joists on 12" centers, compared to 2x4s on 24" centers for the prefab models. A real foundation, not just some 4x4 skids. It looks like a major amount of work, but the result could be a really nice garden shed sturdy enough to house our commercial-grade chipper as well as the big mower.

The price for plans is way too high The price for plans is way too high, but the plans are fairly decent. You DO have to know a little something about construction and adjustments of measurements, but for the most part, not too bad.

The plans are missing a critical step The plans were missing a critical step, and my original message to Shedplans wasn't received. I received a message from them after posting my problem here, and they subsequently sent me the revised instructions. Very grateful for their follow-up. Now if lumber prices would just return to normal....
