Small shed for storing child wagons and such, but tall enough for an adult to stand up in the back. Doubles as a playhouse when the wagons are out and the toy plastic kitchen is brought in. Air circulates but rain does not enter.
Total cost around $350USD and built in a weekend by 2 amateurs (not including planning and material gathering).
Made of long-lasting materials, including Ondura roofing, Hardy (cement fiber)and Polycarbonate siding, and plexiglass windows.
