12x18 Gable Storage Shed Overview

Featuring a roomy interior, this 12×18 gable is a perfect solution for homeowners who have accumulated more stuff than their garage can hold and are looking to reclaim it. The shed delivers 216 square feet of storage space, offering a safe and dry area where you can keep supplies, tools and equipment, outdoor furniture, sports gear, bikes, and other items organized and protected against the elements. You can add hooks to the 7-feet tall walls to hang your rakes, garden hoes, shovels, and ladders off the floor. 

Take advantage of the classic gable roof to hang small items overhead or create additional loft storage space. Some shelves and drawers will also help you maximize the shed’s capacity.

The shed comes with an ultra-wide 64-inch door and stable ramp that allows you to bring virtually everything into place with ease. Its framework utilizes pressure-treated lumber, so you can trust your shed to last for years. Moreover, it is built on a reinforced concrete foundation for durability and performance. 

With its versatile design, this shed can serve as a backyard workshop, pub, home office, home business, pet shelter, chicken coop, or studio. Its wooden side walls allow for easy customization to add features of interest. 

Paint the shed to match it with your house or other outbuildings.
