While "lobby" and "foyer" are often used interchangeably, they can have different meanings depending on the context. A foyer typically refers to the entrance hall of a home or smaller space, while a lobby is usually a larger, more public area found in hotels, office buildings, or other commercial properties.

In a building plan, the lobby is a designated area near the main entrance that serves as a gathering space or waiting area. It often connects to various parts of the building, such as elevators, reception desks, or meeting rooms, and is designed to welcome visitors and direct them to their destinations.

In design, a lobby is the first impression of a building, so its design is crucial. It involves creating an inviting, functional space that reflects the building’s overall aesthetic. This can include elements like seating areas, artwork, lighting, and architectural details that enhance the visitor experience.

A home lobby, often referred to as a foyer or entryway, is the space just inside the main entrance of a house. It's designed to be both functional and welcoming, serving as a transitional area where guests can enter and residents can store everyday items like shoes and coats.
