8 x 10 Garden Shed Plan

Introduction

This 8x10 garden shed combines functional storage with a cottage-style exterior appearance. Besides providing plenty of storage space, it also has ample natural light from two generous windows. The shed could double as a playhouse for your kids or a retreat for you and your hobbies.
The compact size of this garden shed might keep you from having to pull a building permit from your local jurisdiction. Most local codes require permits for outdoor structures over 100 square feet and with 80 under this roof, you'll be well below their threshold.
