Widening or creating a new external doorway will likely fall under permitted development rights, meaning an application for planning permission is not required provided you meet limits and conditions set out in legislation. If the change is on the side or rear of the building it is more likely to comply with planning regulations.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

New external doorways which create a new or widened opening must comply with building regulations as they may impact the structure of a building.

Planning permission is not normally required to turn two properties into one by knocking through a party wall provided the changes are internal and do not impact the external appearance of the property.

You should check with your local planning authority that they agree, and there are not any previous planning changes or conditions which may have an impact.

Additional permissions may be required depending on the building’s history and their location. If the building is listed, an application for listed building consent will be required before any major changes are made to the dwellings.

The work will have to comply with building regulations, the focus will be on structural work and safety.

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.

Work to refit a bathroom with new units and fittings does not generally require building regulations approval, although drainage or electrical works that form part of the refit may require approval under the building regulations.

If a bathroom is to be provided in a room where there wasn't one before, building regulations approval is likely to be required to ensure that the room will have adequate ventilation and drainage, and meet requirements with respect to structural stability, electrical and fire safety.

You do not need planning permission to move internal walls.

Removing a load bearing wall will require building control approval as it is altering the structure of the property. You will be required to provide a report from a structural engineer who will provide structural calculations.

Work on internal walls may also affect fire escape routes, ventilation, drainage or electrics. These should be considered during the design process and work should be carried out by a member of the competent person scheme where possible.
