This in-home storm shelter made of Kevlar and steel provides a safe haven in Category 5 hurricanes and F5 tornados. When the weather's calm, the foundation-anchored structure can double as a closet or powder room. It's ventilated, receives cell phone signals, and installation in an existing home takes less than a day.
Approx. $6500 for a 4x6-foot room; Approx. $9000 for 7x10, installed. Dupont.
