Have you ever wondered why so many large chain stores have two sets of doors? No, it is not just to store shopping carts.

Where I live, any home that is around 100 years old (that hasn't seen any renovations) will very likely have two front doors. Putting it simply, you open one door, step into a small space, and there will be another door in front of you.

The space goes by many names, including: arctic entry, mud room, breeze room, vestibule, airlock, foyer, and more. For sake of simplicity, I am going to call them "entry vestibules."

Entry vestibules create a buffer between the outside and the inside of the building, preventing drafts. This can help greatly with temperature regulation in both the winter cold and summer heat. I can't find number details on energy saving, but the fact that large chains still build them may hint of their importance for money-saving.

In homes, this space also typically serves as the mud room ( a place for shoes and jackets).

In the name of "first impressions," and open concept designs, vestibules are often the first thing to go during renovations, and I think that's a real shame.

I've had two houses over a hundred years old. The first was a "shot gun shack". As soon as you'd open the front door in the winter the thermostat would click. Had some front doors installed dividing the living room from what we called the foyer. It made a big difference. My house now has a mud room at the side door. I've kept the original door which I'm sure isn't energy efficient so it cuts down on draft
