Yes, it is possible to have a bedroom without natural light or a window. There are certain architectural designs and building configurations that can result in rooms without windows, such as inner rooms within a building or basement rooms. Additionally, in some urban areas or high-rise buildings, bedrooms may have limited access to natural light due to their location or orientation.
However, it's important to note that building codes and regulations in many jurisdictions require that habitable rooms, including bedrooms, have access to natural light and ventilation for safety and well-being. These requirements vary by location, and there are typically minimum standards in place to ensure that living spaces have adequate access to daylight and fresh air. These standards aim to prevent issues such as poor air quality, lack of ventilation, and potential health concerns.
If you're considering creating a bedroom without natural light or a window, it's important to consult with local building authorities or professionals to ensure compliance with relevant regulations and to address any potential concerns regarding safety, health, and overall livability.
