14x20 lean to storage shed

Shed overview


The 12’x24’ Longbow Storage Shed is 288 square feet of workable space that can be outfitted with a variety of storage applications. This amount of floor space can accommodate a number of recreational vehicles as well as a riding lawn mower and other outdoor equipment. The windowless design offers more wall space for shelving and storage closets that can be used to lock up harmful pesticides or chemicals and out of reach for children. The shed is built with long-lasting construction material and will provide years of endurance. It can be modified as a “drive-in/drive-out” system by duplicating the door design on the back wall. Architectural shingles or metal roofing can also, be used for the desired look and added performance. The shed can be stained or painted to match the exterior of any house and is very low maintenance.

Premium 12×24 Shed Plan Description


The 12’x24’ Longbow Storage Shed plan is a simplified method for building sizable storage sheds. The plan incorporates a step by step instructional guide that is designed for beginners as well as experienced carpenters. A detailed material list includes information about the types of lumber for the shed and different construction materials needed from start to finish. It utilizes a solid foundation plan with a concrete footing and mortared brick support. The plan includes detailed pictures with measurements for lumber and shows illustrations in 3-D. It helps the builder to understand how the finished product should look and how all of the cut pieces of lumber fit together. A series of smaller steps will guide the builder step-by-step until the shed is complete. It provides different angles of all four sides of the shed as well as the roof and foundation. The plan does a good job at showing the builder how to make the barn-style doors, louvered vents, and door ramp. It also includes a simple, but low-cost and sturdy roof design.

FAQs & Answers


1. Do I need a permit?

A: In most local townships and municipalities, if a shed is less than 100sqft, you do not need a permit. For sheds more than 100sqft, it’s always best to go to your local town office and inquire about a building permit. 

2. How much it would cost me to build?

A: According to most building cost estimator programs, the average cost for materials to build a shed is about $22.85 per square foot. For example, an 8’x10’ shed equals 80sqft x $22.85 = $1,828.00.  

3. How much time will I need to build it?

A: The size of the shed plays a role in how long it will take to build it. An average 8’x10’ shed can be built in 3 to 4 days from start to finish.  

4. Do I need expensive tools or large equipment?

A: You do not need expensive tools, a typical miter and table saw will work just fine. You will also need basic hand tools, corded drill or cordless screw gun, standard 7 1/4’ skill saw, and a variety of garden tools for the foundation. 

5. Can I move my shed to another location?

A: You can move your shed to another location; however, a new foundation will need to be installed. Additionally, interior bracing, heavy-duty straps, and a small crane or front-end loader may be required to safely lift the structure to put it on a trailer or move it to another location on the property.
