This statutory PDF document outlines UK Building Regulations for accessible dwellings, defining M4(1), M4(2), and M4(3) design standards. The document provides formal technical guidance regarding accessibility requirements for residential properties in England. It structures design criteria into three distinct categories: Category 1 for visitable dwellings, Category 2 for accessible and adaptable dwellings, and Category 3 for wheelchair user dwellings. The text details spatial requirements, circulation widths, and installation heights necessary to achieve compliance with the 2015 edition and 2016 amendments. It serves as the primary reference for architects and developers to ensure new residential units meet essential inclusive design standards, covering internal layouts, entrance accessibility, and key living area functionality.
