Building regulations - Approved Documents

The Building Regulations are legal requirements aimed at achieving adequate standards for the constructions of domestic, commercial and industrial buildings.

They are laid down by Parliament and are supported by separate documents containing practical and technical guidance on compliance, which are known as 'Approved Documents'. These have three purposes:

• To ensure the health and safety of people in and around buildings.
• The conservation of energy and sustainability.
• Inclusive access for all and access and facilities for disabled people.

Summary of the Approved Documents

The Building Regulations are supported by Approved Documents, which indicate how compliance with the Regulations may be achieved.  The approved documents are split into 14 key parts and a number of guidance notes.  These are listed below:

Part A - Structural Safety - Summary

• requires buildings to be built in a way ensuring no collapse will occur disproportionate to its cause.
• ground movement such as freezing of subsoil will not impair the stability of the building.
