Practical points
- Count the largest number of people on site at one time, not total headcount.
- Public buildings and venues are sized using BS 6465, which allows for visitors as well as staff.
- Accessible and ambulant facilities are needed in addition to the numbers above where Approved Document M applies.
- Approved Document T affects how toilets are arranged on new non-domestic buildings in England.
