16×20 Garage Shed Overview

There are endless uses for a classic garage shed conveniently set in your backyard. This 16 x 20 garage shed is a solidly built facility that delivers plenty of space. It is a perfect option for homeowners and passionate gardeners who need ample storage space for their vehicles and other items. The shed offers a massive 320 square feet of floor space, enough for parking your car and keeping all your belongings, including ATVs, riding lawnmowers, snow blowers, rototillers, wheelbarrows, bikes, and power tools, carefully organized and protected from bad weather and elements.

The shed is set on a reinforced platform and features 8-feet wide access to bring everything inside with minimal hassle.

Even better, this outbuilding’s functional design allows you to customize it, so it serves other purposes. You can transform it into a home office, workshop, studio, or storage facility for your gardening tools and landscaping equipment with its spacious interior. It is fitted with a 6′ x 2′ 8″ door, so it will serve either purpose effectively. There are also 3′ 4″ sided square windows that let in enough light.

The two doors have sturdy ramps to allow you to wheel equipment into place. A gable-style roof crowns the sturdy structure, making it weather-tight completely.

Get this plan and build yourself a spacious garage.
