House Plans with Air Lock (Closed) Foyers

An air lock foyer is a small enclosed entry with two doors. It traps wind, dust, and cold air between them so they don't reach the living space, an effect long called an air trap or windbreak.

For homes in cold climates, in windy regions, or on a dusty rural lot, that buffer cuts drafts and heat loss. It also gives a spot to leave muddy boots before entering the main house.
