Garden Igloo
Simple to set up and environmentally friendly, the Garden Igloo is an interesting alternative to the backyard hideout. The frame of this geodesic dome is made with PVC struts and high-strength nylon joints, and covered by a transparent PVC cover. It's over seven feet tall at its highest point and nearly 12 feet in diameter, so there's plenty of room inside, and should you decide you'd rather have shade than shelter, the optional canopy cover offers added privacy from the rear and an open entrance that's ideal for warmer weather.
