Indoor design mezzanine ground level

Quick answer：

Mezzanine and ground level in indoor design refer to the architectural elements that create additional space within a building. A mezzanine is a raised platform within a room, typically used for storage, office space, or as an additional living area. Ground level, on the other hand, refers to the floor at the base of a building, which is usually the main living or working space. Both elements are important for optimizing space and functionality in residential or commercial buildings.
