Love this idea!--- for the next house you build - Pocket gate for kids or pets. One of the best ideas I've ever seen. I could see doing this instead of a baby gate between the kitchen and living room area or the basement stairs etc.
secret door to an underground storm shelter/panic room/hid out in the kitchen island! Best secret passage ever! Definitely a dream home feature! (would also be good if someone broke into your house and you had to hide somewhere) Zombie apocalypse.
