Balconies, verandas and raised platforms will often require planning permission as they do not fall under permitted development rights.

An exception to this is Juliet balconies which do not have any external access or platform, allowing them to be classed as permitted development.

A raised platform of under 0.3 metres is also allowed without planning permission, this may be an area with slightly raised decking.

When applying for planning permission for a balcony it is important to consider your neighbours privacy and garden. The features and location of the property may have a significant impact. If the building is listed or in a conservation area, then this may have a bearing on any decisions.

Your planning application must be made up of:

• The necessary plans of the site
• The required supporting documentation
• The completed form
• The correct fee.

The local planning authority will not be able to process your application unless the mandatory supporting documentation has been provided. You can also attach any other relevant documentation which you think will help the local authority determine the application.

What supporting documentation must be provided depends on the application type,  development type and local planning authority.

There are two levels of mandatory documents, national and local. If you’re applying online, the service will tell you what mandatory documentation you need to provide and allows you to attach the relevant documents. Most applications will require you to provide a location plan and a site plan.

In addition to the national list, your LPA may produce a list which details any specific documentation that is required to accompany the application. The requirements may vary according to the type of application, i.e. household, full, outline, etc. If you are applying online, this list is available from the supporting documents screen or your local planning authority’s 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.

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.

Creating a new basement will usually require planning permission, particularly if it affects the external appearance of the property. For example, installing a lightwell to bring natural light into the basement may be subject to stricter design rules if it is visible from the street, especially at the front of the property, compared to those at the rear or side.

Because basement construction involves significant excavation and structural work, permission is often necessary. It’s recommended that you consult your local planning authority early on to understand what is likely to be considered acceptable before submitting a planning application. Building regulations will also apply to a new or conversion of a basement.
