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.

A designated area is situated within a World Heritage Site, Conservation Area, Site of Special Scientific Interest, National Park, or an Area of Outstanding Natural Beauty, the area is protected by law due to its architectural or historic interest or landscape.

Due to this protection, there will be further limits on what you can do to your property if it is within such an area, for example building an extension, changes to the roof, or work to trees. Restrictions will be put in place and permitted development rights will not apply.

If you live in a designated area, you must seek advice from your local planning authority before starting any work.

Adding a new driveway to an unclassified road for access to a house or business falls under permitted development rights, meaning no application for planning permission is required.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

You will have to apply to the relevant highway authority for a dropped kerb if you wish to cross a pavement to access your property.

Removing a chimney stack may fall under permitted development rights, meaning no application for planning permission is required provided certain limits and conditions are met.

The permitted development right which covers this focuses on the installation, alteration or replacement of a chimney, note that this does not specifically mention removal. Rules in a conservation area may differ, in this instance you should contact your local planning authority directly to understand their position, and if the building is listed, then you will need listed building consent.

To ensure that the local planning authority will allow the removal of the chimney stack you can apply for a lawful development certificate. If approved, then no enforcement action can be taken against the change.

If the chimney is shared (i.e. as part of a terrace), you might need to discuss with relevant neighbour and obtain a party wall agreement.

Building regulations approval may not be required if you are removing the external chimney stack above the roof. If works progress to the internal chimney stack or breasts, then it will require building regulations to understand the structural impact.

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.
