Unterbasen
Unterbasen, also known as subbasements or lower basements, are additional levels of underground space constructed below the primary basement of a building. They are typically used for various purposes such as parking, storage, or additional living spaces. The construction of unterbasen can be particularly common in urban areas where space is at a premium. These spaces are often accessed through a separate entrance or a staircase leading down from the main basement. The design and layout of unterbasen can vary widely depending on the specific needs and constraints of the building and its surroundings. In some cases, unterbasen may be integrated into the overall building design, while in others, they may be added as an afterthought to maximize the use of available space. The construction of unterbasen requires careful consideration of structural integrity, ventilation, and safety measures to ensure they are functional and safe for their intended use.
