how to make a secret door a room or closet. I think we'll figure out how to do this for double doors. I have double doors between my sew/craft room and what will be the dining room. more storage in what would have been lost space .
Simple built-in to create a mudroom and/or storage anywhere from an entry, to kids room or in a laundry room by adding shelves or a deeper bench for sitting. Put drawers under bench or have the seat lift up to store things.
