Land and buildings are categorised by their type and purpose through a system known as ‘use classes’. A 'Change of use' can be within the same Use Class or from one Use Class to another.

You can find a full list of use classes and change of use scenarios related to planning on the Planning Portal website.

Firewalls provide protection against fires spread which may occur to neighbouring properties. Building regulations ensure that modern homes are fitted with firewalls as well as other fire safety measures such as adequate fire escapes and alarm systems.

Older homes may not have a firewall installed in the loft, especially in homes with shared loft spaces. There is no requirement to retrospectively install a firewall, but it should be considered to improve the safety of your home and those living in it.

As an adjoining loft firewall is a party wall, you will need to talk to your neighbour to discuss the work.

Planning permission may be required for external insulation if it impacts the external appearance of the building. If materials are of a similar appearance to those used in the construction of the house, then permission will likely not be required.

Listed buildings will require listed building consent for any significant work.

If you live in a Conservation Area or other protected area you will need to apply for planning permission before making changes to the outside of your house.

Further information and building regulations advice is available on Planning Portal. Read our external walls common project.

A bin store is classed as an outbuilding, these fall under permitted development rules meaning they are allowed as long as they adhere to a set list of rules. However, one of these rules is that outbuildings cannot be placed in front of the principal elevation*. As such, you will be required to apply for planning permission to build a bin store or any permanent structure in your front garden.

Read more about the rules for outbuildings.

‍Principal elevation - The most visible or prominent side of a structure, typically facing a street or public area. While often considered the 'front' of the building, it may not always contain the main entrance.

If the garage will remain in domestic use - for example, as a personal hobby or home workshop - then planning permission is typically not required.  

However, it’s important to check whether there are any planning conditions, covenants, or restrictions attached to your property or the garage itself that may limit or prevent conversion.
