Inserting new windows which look similar to those previously used in the house will often not require planning permission. Some rules apply to new additions, for example if they are on an upper-floor side elevation they must be obscure glazed and non-opening or more than 1.7 metres above the floor.

Installing a new bay window on the front elevation would require planning permission as it is classed as a forward extension.

If you live in a listed building or conservation area you should contact your local planning authority.

 Any new openings will have to comply with building regulations, this may impact thermal heat loss, structure, ventilation and fire safety.

You can use a member of a competent person scheme to complete any work, this will ensure that the work is completed in-line with regulations.

A pergola is classed as permitted development, meaning an application for planning permission is not required provided it meets specified conditions and limits.

Outbuildings cannot be installed on the principal elevation of the property, additionally any platform must not exceed 0.3 metres in height.

If the building is listed, then you will need to apply for listed building consent and planning permission for the change.

For more details read our outbuildings common project.

National planning regulations allow certain alterations to be made to a property without requiring planning permission; these are known as permitted development rights. In some cases, local authorities may remove or restrict these rights for specific types of development that would otherwise be allowed. This is achieved through the use of Article 4 Directions, which are intended to protect the character, heritage, and appearance of designated areas.

If your local planning authority has issued an Article 4 Direction, some of your permitted development rights may no longer apply. As a result, you may need to submit a planning application for works that would not normally require one.

You can check whether an Article 4 Direction affects your property by visiting your local authority’s website.

It is likely that you will require planning permission to extend an existing front porch to add a toilet.

Adding a porch falls within permitted development rights meaning an application for planning permission is not required provided specified limits and conditions are met. However, to fall under permitted development rights for a porch, the total ground area must not exceed three square metres. This is unlikely to be enough room to fit toilet and the required additional components.

Read the full rules for porches under permitted development on our mini guides.

If your porch exceeds these limits, it will be classified as an extension. These can be permitted development but come with a different set of rules.

Extensions are not permitted development if they are built forward of the ‘principal elevation’ of the house. As such, you will be required to submit an application for planning permission to your local planning authority.

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

Changing a standard garage door to an electric garage door will not normally require planning permission. Instead, they are covered by permitted development rights.

Permission may be required if your property is listed, you live in a conservation area or there will be a visual impact on the appearance of the house as viewed from the street. If you are unsure, it is advised that you contact your local planning authority.

Work to install an electric garage door must comply with Part P of the building regulations. This can be done by using an electrician who is registered with the competent person scheme.
