Lower ground floor refers to a level or storey of a building that is below the ground level or the main ground floor. It is commonly found in urban buildings and serves various purposes, often providing additional space for residential, commercial, or functional activities.
The lower ground floor is situated beneath the ground level and can be accessed through staircases or elevators. Although it is below the principal ground floor, it is not defined as a basement as it is still considered part of the main structure and usually has windows or entry points for natural light and ventilation.
This area is utilized for different functions depending on the building's purpose. In residential buildings, lower ground floors are commonly used as additional living spaces, such as bedrooms, libraries, playrooms, or storage areas. Commercial buildings often allocate lower ground floors for retail spaces, restaurants, gyms, or conference rooms. Additionally, the lower ground floor may house utility rooms, such as plant rooms, storage rooms, or even parking facilities.
The lower ground floor plays a crucial role in optimizing space utilization, especially in densely populated areas where land is scarce. By expanding below ground level, buildings are able to maximize their footprint while accommodating the various needs of occupants.
