Like other ready-made sheds, the Keter Fusion eschews raw wood in favor of a composite, better able to endure year-round weather exposure. However, despite requiring next to nothing in the way of maintenance, the rugged construction of the shed manages to retain the look of wood, even down to the natural finish and texture of its shiplap-style siding. Inside, strategically placed beneath the steel-reinforced roof, there are air vents to help prevent dampness and odor. Plus, there's plenty of natural light, thanks not only to the windows set into the double doors, but also to a skylight that runs the full length of the rustic yet modern, easy-to-assemble shed. Available at Amazon; $1,800.
