Kids have amazing imaginations. One minute, they're playing house with pots and pans, the next they're sword-fighting pirates, playing with twigs from the front yard. One creative dad made his adorable daughter a simple playhouse to fuel her imagination. Using plywood, he whipped up a split-level space, complete with electricity, in just 4 days. The basic design means his daughter can turn the house into a spaceship, a castle, or anything else she can dream up.
