I have a small space and a normally opening door takes up too much room. Is it possible to have a door that swings out and slides along the wall like the side door on a van or SUV? If anyone knows how this can be done, I would love to hear about it. To clarify - this is an exterior door, so it would need to be inset and secure once it is closed. I thought of a van because this is how the doors work! A pocket door would not work, as it would interfere with exterior insulation (I live in the NE, cold climate).
