12 x 16 Storage Shed Plan

Introduction

With 192 square feet, a shed this size will allow you to store virtually anything. The double doors on the shed open to five feet across, which gives you plenty of room to move the bulkiest and most awkward equipment or furniture in and out of the shed. The building has two fresh air vents in the gable-end walls that will keep the air fresh even when the doors are tightly locked.
The wall cavities have ample space for wiring and plumbing. If you're going to place it far from a power source, the roof is more than ample for solar panels to electrify the building. Not only will they hold the weight of solar panels, there may be room inside the shed for battery storage.
