What is the minimum depth of the area before entrance vestibules according to BP 344?

The minimum depth of the area before entrance vestibules, as stipulated by BP 344, is set at 1.8 meters. This requirement is established to ensure accessibility and convenience for all individuals, particularly those with mobility impairments. The depth allows sufficient space for movement and maneuvering, especially for those using wheelchairs or other mobility aids, thereby promoting inclusivity in building design. This standard directly reflects the intention behind BP 344, which emphasizes the importance of accessibility in public and private spaces. By maintaining a minimum depth of 1.8 meters, designers can create an environment that is easier to navigate, thereby fulfilling legal and ethical responsibilities to provide accessible facilities for everyone.
