You don't actually need to own land or property to apply for planning permission for it. This means you can apply for permission before deciding whether or not to buy a piece of land.

The following people must be informed about a planning application relating to land or buildings that they have an interest in:

• The owner or all the part-owner/s (if you are not the full owner)
• Any leaseholders with at least seven years' lease remaining
• Any agricultural tenants.

You can contact your local planning authority for pre-application advice or book an appointment with our Planning Guidance Service.

Find out more about pre-application advice.

A soakaway does not normally require an application for planning permission provided it deals with surface water and does not discharge into a public sewer. Additional regulations may apply if you are in a conservation area or within the boundary of a listed building.

Building regulations will apply to the creation of a soakaway. The soakaway must comply with Part H of the building regulations which specifies where they can be located and the size that is permitted.

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.

Adding a storey on top of an extension will always require an application for planning permission.

If you want to add a storey on top of your house under permitted development rights, it must be on the principal part of the house.

If you want to add an additional storey on top of your house, it can be permitted development. It is only permitted development if it follows certain rules:

The current house

• Is not a building containing one or more flats, or a flat contained within such a building
• Was constructed between 1 July 1948 and 28 October 2018
• Has not already had additional storeys added to it
• Is not on Article 2(3) land or a site of special scientific interest
• Was not changed to be used as a house (from a previous non-residential use) under permitted development rights.

How many storeys can you add?

• If the house is one storey then one storey can be added
• If the house is two or more storeys then two storeys can be added

Where can the storeys be added?

• The additional storeys must be added to the principal part of the house. The principal part of the house is the main part of the house excluding any front, side or rear extension of a lower height (regardless of these being part of the original house or subsequent additions).
• Engineering operations must only include works within the existing curtilage of the house to strengthen existing walls and foundations

How high can it be?

• The house cannot exceed 18 metres in total height
• Each storey cannot add more than 3.5 metres to the total height
• If the house is not detached the total height cannot be more than 3.5 metres higher than the next highest building that the house is attached to, adjoins, or is in the same row as.
• The additional storeys must not exceed 3 metres in height or the height of any existing storey in the principal part of the house (measured internally from floor to ceiling)

What materials can be used?

The materials used must be of a similar appearance to those used in the construction of the exterior of the current house

Where can windows be placed?

Windows must not be placed in any wall or roof slope forming a side elevation of the house.

Following completion of development:

• The house must remain in use as a domestic residential property
• No visible support structures must remain on or attached to the exterior of the house
• The roof pitch of the principal part of the house must be the same as it was prior to the development.

 If any of the limits set out above are exceeded then an application for planning permission will be required. If you are unsure, you should contact your local planning authority.

You can put one flagpole up to 4.6 metres high in your garden without needing to apply for planning permission. If it is higher than this or you live in a protected area such as a Conservation Area or listed building then consent will be required.

Certain flags can be flown without needing consent, such as national flags.

Read government guidance on flying flags for more information.
