Part T

Toilet Accommodation

Building regulations effective 1 October 2024 governing the provision of toilet accommodation in non-domestic buildings: minimum proportions of universal toilets, separate-sex facilities, and ambulant accessible WCs in new and materially altered non-domestic buildings. Does not apply to dwellings, so out of scope for ordinary domestic extensions. Included in the graph for completeness when the site covers commercial conversions or mixed-use schemes.

The buildwiz build guides walk through a UK extension in sequence and link to Part T (and every other Approved Document) at the exact stage it bites. That is usually a more productive way to use this material than reading the document cover to cover.
