Verandas will often require planning permission as they do not fall under permitted development rights. If the veranda is raised over 0.3 metres, covers more than 50% of the land around your house, is on the principal elevation or on a roof then it will need planning permission.

You may require additional consents if you live in a Conservation Area or listed building. If you are unsure, you should contact your local planning authority.

For more information about planning permission for verandas and balconies, read our common project.

A carport can fall under permitted development rights provided it meets certain limits and conditions set out in legislation. If you exceed or fail to meet a requirement then you will require planning permission.

If not attached to the house, a car port will be treated as an ‘outbuilding’. A full list of requirements is available on our outbuildings common project.

No, a two-storey extension will always require planning permission. Permitted development rights only allow for certain types of single-storey extensions without the need for a planning application, provided they meet specific criteria. All extensions of more than one storey fall outside of these rights and must be assessed through the formal planning process requiring householder planning permission.

Foundations are required to carry and distribute the load of the building safely. Therefore, all buildings should have adequate foundations. The factors that need to be considered when designing a foundation are:

• Type of soil

• Adjacent structures

• Trees

• Drains and sewers

• Size and construction of the new building

• Ground condition

• Landfill sites

It is advisable to contact a structural engineer or speak to a building control body about plans for new foundations.

There are different planning fees for England and Wales, and many different application types depending on the work being carried out.

You can use the Planning Portal's fee calculator to work out fees for different kinds of proposal.

Use the fee calculator (England)

Use the fee calculator (Wales)

While every effort has been taken to ensure that the fee has been calculated correctly, the determination of whether a planning fee is correct is the responsibility of the relevant local planning authority, who will check the fee is correct when the application is submitted and validated.
