Air Locks

 of course you don't want an outside door to open directly into the great
outdoors.  We made a little space outside with another door.
It's a great space to leave shoes and boots. and firewood. Etc.
It sure buffers the cold winds.

Here in the real world, that's called a "mud room."

Can you post a picture of that. I bet it would be a hoot.

 

and to clarify ; an air lock should be on any outside door. maybe even
to the garage.
a mud room is only found on the back door.
Happy Solstice all !

How hard would it be to add one of these as a DIY project?
