Skylit foyers are a type of architectural feature found in many buildings. They are typically open-air spaces located at the entrance of a building, often with a skylight or other source of natural light. The term 'atria' is used to refer to these spaces, which can be used for a variety of purposes such as providing a place for visitors to wait or providing an area for plants and other decorations. Skylit foyers are a popular design choice for many modern buildings, as they provide a bright and inviting atmosphere.
