If you are considering building your own extension and are finding the building regulations difficult to get your head around, then read on for some of our best frequently asked questions about extensions. 

What are building regulations?

Building regulations are basically legislation detailing the methods and requirements for the construction of buildings. Originally building regulations were first brought about as a direct result of the Great Fire of London in 1666 and as such they were primarily concerned with the safety of a building’s structure and its resistance to fire. However, as the centuries have passed, building regulations have focused upon a wider range of issues including the most recent requirements as regards energy efficiency and ensuring that buildings are more environmentally friendly. By complying with building regulations when building extensions, you are ensuring that you will end up with a building which is safe to work and live in.  

When do building regulations apply?

Building regulations apply to practically all new building works and extensions and any other structural alterations which may be carried out on a building. Building regulations will apply in a range of differing situations and you should always investigate which regulations apply if you are in the following situations:

• building a new building
• building an extension on an existing building
• altering or changing an existing building
• providing fittings
• underpinning foundations

Are there any exceptions when building work may be exempt from building regulations?

Yes there are a number of circumstances when the building work may be exempt from regulations, these include:

• A porch area which is less than 30m squared
• Small, detached, single-storey buildings which contain no bedrooms and which are smaller than 30m squared and built of non-combustible materials. These type of buildings may include garages, sheds and greenhouses
• An open-structured carport which is less than 30m squared and has more than two sides open
• Buildings not frequented by people
• A ground level conservatory, less than 30m squared

If you are unsure whether the Building Regulations apply then you would be best advised to contact your local authority Building Control Officer or an Approved Inspector.

How do I apply for building regulation approval?

If you are interested in building an extension then you will first need to make sure that you acquire building regulations approval.  You can either do this through Full Plans Submission or Building Notice. Your local authority Building Control Officer should be able to confirm how to proceed with either of these situations.
