You could pay hundreds of dollars for a play fort for the kids -- and we're sure they would enjoy it -- but why not build the project yourself? Not only will your family appreciate your effort, but you'll save money in the process. Fort features simple, sturdy construction and has an optional sandbox under the fort, with one also at the end of the slide. A list of the materials you need is provided along with measured drawings and clear instructions. Your success is guaranteed, but you have our weekday customer support if you need it. Canvas rainshield, slide, and hardware materials are commonly available at local fabric and hardware stores. Don't spend $600!! Build this project with a circular saw and common hand tools. 6' square, 10' tall to the top post.
