2:30 intresting that is sort of kind of simular in Sweden. In Sweden most buildings have a air lock to keep the cold out. For flats, the airlock is typically in the main entrance. But in a house, there is normally a small room that is the airlock right outside of the main hallway (or that is also common, the kitchen double up as the main hallway. You always take of your shoes there and walk around in your socks... But there is one is one exception is typically in summer houses when there is a summer party. Then you typically can walk in the house with shoes. Of cause, during the summer the shoes will be way cleaner, and also the airlock will be fully open during summer month. Also summer parties is often a inside come outside event. Also pretty common is a winter garden with floor to ceiling glass doors. Those are typically fully open during summer parties and this will give the effect in houses that have floor to cealing window doors both to the inside and outside of the winter garden that there is no border between indoors and outdoors.
