ACCESS TO AND USE OF BUILDINGS
Means of escape in case of fire: the scope of Part M and AD M is limited to matters of access to, into and use of a building. It does not extend to means of escape in the event of fire, for which reference should be made to Approved Document B – ‘Fire Safety’.
Stairs and ramps: Approved Document K (Protection from falling, collision and impact) contains guidance on internal and external steps, stairs and ramps when they are part of the building. Additional guidance is provided in this Approved Document when external stepped and ramped access also form part of the principal entrances and alternative accessible entrances, and when they form part of the access route to the building from the boundary of the site and car parking.
Manifestation on glazed doors and glazed screens: Approved Document K (Protection from falling, collision and impact) contains guidance on manifestation.
BS 8300:2001 Design of buildings and their approaches to meet the needs of disabled people. Code of Practice: this supersedes BS 5619:1978 and BS 5810:1979. BS 8300 provides guidance on good practice in the design of domestic and non-domestic buildings and their approaches so that they are convenient
to use by disabled people. The design recommendations are based on user trials and validated desk studies which formed part of a research project commissioned in 1997 and 2001 by DETR. The guidance in this Approved Document is based on and is complementary to the BS, although the BS contains much additional material that is not apt for, or not considered appropriate for, inclusion in guidance accompanying regulation. Also, in a few cases, the guidance in AD M differs from the recommendation in BS 8300. Compliance with the recommendations in the BS, therefore, while ensuring good practice, is not necessarily equivalent to compliance with the guidance in AD M.
Attention is drawn to the following extracts from The Building Regulations 2010.
Interpretation (Regulation 2)
Regulation 2 contains the following definition:
‘independent access’ means in relation to a part of a building (including any extension to that building) a route of access to that part which does not require the user to pass through any other part of the building.
The meanings of the expressions ‘institution’, ‘public building’ and ‘shop’ used in Regulation 5 are explained in Regulation 2.
Meaning of material change of use (regulation 5)
For the purposes of paragraph 8 (1)(e) of Schedule 1 to the Act and for the purposes of these Regulations, there is a material change of use where there is a change in the purposes for which or the circumstances in which a building is used, so that after the change:
a. the building is used as a dwelling, where previously it was not;
b. the building contains a flat, where previously it did not;
c. the building is used as an hotel or a boarding house, where previously it was not;
d. the building is used as an institution, where previously it was not;
e. the building is used as a public building, where previously it was not;
f. the building is not a building described in Classes 1 to 6 in Schedule 2, where previously it was;
g. the building, which contains at least one dwelling, contains a greater or lesser number of dwellings than it did previously;
h. the building contains a room for residential purposes, where previously it did not;
I. the building, which contains at least one room for residential purposes, contains a greater or lesser number of such rooms than it did previously; or
J. the building is used as a shop, where previously it was not.

a. that part complies in all cases with any applicable requirements referred to in paragraph (1)(a);
b. in a case to which sub-paragraphs (b), (d), (e) or (f) of paragraph (1) apply, that part complies with the requirements referred to in the relevant sub-paragraph;
