A vestibule is a modern term for the area surrounding the external entrance. It serves as a transitional space between the external and inside structures. It frequently links an entryway to a lobby or hallway. It is the space occupied after passing through the door but before entering the building's main interior. The word comes from Latin vestibulum, meaning "cloak room," which in turn comes from the Greek kleos "cloak" + temenos "sacred place." In medieval Europe, a vestibule was where one changed clothes before entering a holy site such as a church or mosque.
In buildings with more than one entrance, such as hotels, restaurants, and museums, there may be separate vestibules for each entrance. Each vestibule usually contains information about guests and staff, as well as some storage space.
Vestibules are often tiled or have wood floors to make them comfortable for visitors while they wait for their rooms to be ready. They may also have plants in them to add color and reduce the feeling that people are waiting in a cold, empty space.
Hotel vestibules are usually small, so it's important to be aware of what you put into your backpack when checking it at the front desk. You don't want to fill up all the space or cause other travelers to walk around with their arms full!
Doors, windows, ventilators, and other similar devices are collectively referred to as "openings" in some technical situations. (I suppose I could remark that apertures raise the cost of a concrete construction.) You'll observe that apertures can be interpreted to be framed (in wood, metal, etc.) rather than simply being voids of material. This is true even if they are completely open; for example, a door might have a frame around it, even though only the edge of the door is visible outside of the building.
Doorways and window openings are usually graded or sloped to allow water to run off of their roofs or walls. These are called "slopes". The angle varies depending on how much water is expected to collect on the roof or floor but it usually ranges from 1 degree to 45 degrees. A slope of 1 degree means that any water that falls from above will be directed right back into the sky, while a slope of 45 degrees would cause any rain or snow to remain on the ground.
The grading of a site should be considered when choosing materials for your house openings. For example, if you plan to use brick for your exterior wall, then those walls should have a slope of not more than 15 degrees to allow water to drain away from the house. If the site is flat, however, then you can choose to build without slopes or with very shallow ones instead.
Household openings include doorways, windows, and chimneys.
The door, hallway, or general area of a building's entrance is referred to as an entryway. An entrance is the opening, doorway, or tiny room that you pass through on your way inside a house or structure.
The distinction is that an entrance is an aperture or hallway that allows entry into a structure, but a foyer is a lobby, corridor, or waiting area of a hotel, theater, or other establishment. Both terms may be used to describe any room or area where guests can check their bags before entering a more private space.
In homes, the term "entryway" is commonly used to describe the area inside a house where keys are kept in a hook or rack, and coats are stored on a closet rod. This is usually a small room with a door that leads into a larger living room or hall. The word "foyer" is often used instead. Even when these rooms are not specifically named, they still function as entryways because they are areas where people can leave their belongings before moving further into the home.
People use the words "entryway" and "foyer" interchangeably, but they have different definitions with different implications. An entryway is a small room where you can leave your bag before going into another part of the house; a foyer is a large room with a staircase leading up to other floors of the building where guests can see their luggage being held while they enter a party or event.
