Main changes made by the 2023 amendments

Clarification is also provided on how the how the capacities should be derived in these buildings.
Provision of toilet accommodation
Design considerations
Replace 5.6 with the following:
5.6The provision of an enlarged cubicle in a separate-sex toilet washroom can be of benefit to ambulant disabled people, as well as parents with children and people (e.g. those with luggage) who need an enlarged space. In large building developments, separate facilities for baby changing and an enlarged unisex toilet incorporating an adult changing table are desirable. Changing places toilets, facilities designed for individuals with complex and multiple impairments who may require the assistance of up to two assistants, should be provided in addition to any wheelchair accessible accommodation in separate sex toilet washrooms, wheelchair accessible unisex toileting facilities and baby changing facilities.
Further guidance on layout and equipment is available from the Changing Places Consortium campaign website: www.changing-places.org and by reference to guidance in section 18.6, diagram 48 and annexes F and G of BS 8300-2-2018
Note: For specific guidance on the provision of sanitary accommodation in sports buildings, refer to ‘Access for Disabled People’.
