Airy lobbies are a type of architectural feature found in many buildings. They are open, airy spaces that are usually located at the entrance of a building. The term 'airy lobbies' is derived from the Latin word 'atria, ' which means an open courtyard or hall. Atria were often used in ancient Roman architecture to provide light and ventilation to the interior of a building. Today, airy lobbies are still used to provide a welcoming atmosphere to visitors and to create a sense of openness and spaciousness.
