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.
@Blair Older houses in my country also have them, and they’re called just like that: vestibules. And what’s interesting is that the buildings from the communist era also have them. I grew up with them being called simply “holul de la intrare” (literally just “the entry hallway”). Indeed, it’s a place where everyone leaves their jackets and shoes so that they do not bring all the dirt inside the house. In fact, my studio has an entry hallway as well, but I rarely close the door fwiw.
Newer buildings, if I recall correctly, tend to blur this demarcation, as they try to turn everything in an open space (so that it looks bigger) - as such, there’s usually no door that leads to that little hallway - probably because having an AC makes it less important to have another door after you get inside the house. But I saw that it’s still properly marked by walls, so you know in your mind where to leave your shoes, your jacket etc.
Well businesses use them because there is so much traffic coming and going. Hope you don’t have that much at your place.
I could only think that we have better weatherproofing around doors now (and better doors themselves too with better insulation). And the rest of the house is better insulated and air tight too, so less of a need. We used to have screen doors that cut the wind as well, don’t see many of those but those could come back. Interesting idea but I can’t really see them coming back, especially with many new houses being those small skinny houses.
Smaller houses had them too. I have been in a ton of houses from the early 1900s or late 1800s that had the entry vestibules.
You are right that advances in insulation and HVAC have made them less common. Another factor is people tend to come in through a garage, so there is a mud and/or laundry room there that acts in the same capacity. Older homes usually only had a back door and a front door with no garage so the main point of entry for the homeowners was the front door. Larger homes did sometimes have a porte cochere with a side entry to the home with a mud room, those houses usually had a garage built onto the home where the porte cochere was.
It’s blocks airflow when only one door is open. A cache of sorts. Insulation isn’t really the issue, since a single door allows free airflow, regardless of how well insulated the door is.
It’s also part of why revolving doors are useful (though those also help with stack pressure in multi-story buildings).
If only the sq ft of living space was affordable enough to have a shoe and jacket room. Nevermind getting two people into a space like this.
I grew up in a rural/small town area where mud rooms are still highly valued to this day. Even small houses will occasionally have mud rooms.
It won’t be very long. The house bubble will settle over the rural Midwest. It’s already begun. 3br 1bath 1k sq ft are already north of 300k. The one dollar tree in town won’t support it. Trailer parks are already getting bought up by equity. We need guillotineabules, not vestibules.
I mean I agree with you, but in my small Midwestern town, it’s cheaper and easier house maintenance to have a mud room instead of constantly cleaning the floor in front of the door. I think houses in the cities will see them disappear, but not in places where the towns are ~300 to 50k people. It might become hard to find in small houses in the Midwest, but it will still be there in most mid sized houses
Fun fact: The german term I learned for his literally translates to the “windcatch”.
Edit: It’s “Windfang” in German
