Adding air conditioning to your home is considered permitted development provided all the limits and conditions set out in legislation are met. The limits set out the size, placement and quantity of air conditioning units allowed.
If your home is in a protected area such as a Conservation Area then permission will be required. If you live in a listed building then consent will be required.
The installation of air conditioning must comply with building regulations. It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Scheme.
For more information on air conditioning, read our heat pumps common project.
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.
Work to the roof of a house (e.g. re-roofing) that does not change its external appearance will usually not require an application planning permission as it is classed as ‘permitted development’. There are certain conditions and limits that need to be met to qualify for permitted development rights.

A new roof must comply with building regulations to ensure it is structurally safe, energy efficient and properly ventilated.
A garden gazebo or freestanding awning will often fall under permitted development rights provided it abides by the restrictions set out by government. In this instance a garden gazebo or freestanding awning will be classed as an outbuilding and should not be in front of the house or more than 2.5 metres in height.
Different rules apply if the awning is attached to the house itself. It may still be permitted development, but falls under the class of enlargement, improvement or alteration.

Yes, in most cases you can use an outbuilding as a home office without needing planning permission. As long as the use remains incidental to the main dwelling it is still considered part of your domestic residential use.
The green belt is a specially designated area of countryside protected from most forms of development. It is protected to help stop urban sprawl, preserve the character of existing settlements and encourage development within existing built-up areas.
The government are working on improving access to public land records, allowing you to check certain restrictions on land. You can view their progress here and see whether your land is greenbelt (note: this tool is currently under development).
You should contact your local planning authority to find out if your land is in a green belt area, and any policies or restrictions that may apply as a result.
