In many circumstances, rules known as ‘permitted development’ rights allow you to extend a house without needing to apply for planning permission, providing specific limitations and conditions are met. If you want to exceed these limits and conditions, then it is likely that an application for householder planning permission will be required.

The limits and conditions for building an extension under permitted development rules are covered in our guidance on the Planning Portal, and there are other points to take into consideration.

If you plan to put up a small, detached building like a garden shed, garden room, garden office, annexe or summerhouse (all classed as outbuildings), building regulations generally won’t apply if the building has a floor area under 15 square metres and does not include any sleeping accommodation.

For buildings with a floor area between 15 and 30 square metres, building regulations approval is usually not needed - as long as the building does not include sleeping accommodation and either:

• it is at least one metre away from any boundary, or
• it is built mainly from non-combustible materials.

Removing a non-load bearing wall will likely not require building control approval provided it does not affect fire escape routes, ventilation, drainage or electrics.

It is best practice to get a report from a structural engineer to ensure the wall is non-load bearing prior to starting any work.

Running a taxi business from home will require planning permission as it constitutes a change of use of the property. The business may cause increased traffic or visitors, staff being in the property and external advertising, all of which would have an impact on the surrounding area.

You should contact your local planning authority or the Planning Guidance Service for more advice.

Demolishing and building a new lean-to will still have comply with planning requirements.

If you live in a conservation area or listed building you may require approval for the demolition.

Whether a lean-to requires planning permission will depend on what the lean-to is used for, it may be an extension, pergola, carport, conservatory or gazebo.

In some cases a building a lean-to will be classified as permitted development, meaning an application for planning permission is not required provided specified limits and conditions are met. If these are exceeded, then you must apply for planning permission.

Permitted development rules vary based on the type of work you are completing, visit our interactive house mini guides for details on the specific rules.

If you live in a listed building, you will need listed building consent for any significant changes.
