Do I need permission to create an opening for a new window?
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.
Common Questions
If an outdoor kitchen is not a permanent structure, then planning permission will normally not be required.
Where planning permission is required, it may be granted through permitted development rights, provided it meets the limits set out in legislation. Most outdoor kitchens fall within the set limits unless they are particularly tall or close to a boundary.
While there is no specific permitted development right for ‘outdoor kitchens’ it may be classified as an ‘outbuilding’.

If the structure exceeds the limits set out through permitted development rights, then it will require an application for planning permission.
Different rules may apply if you live in a listed building or conservation area. If this is the case, you may wish to consult your local planning authority.
Read about the building regulations that cover outdoor kitchens.
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.
Building a porch at ground level and under 30 square metres in floor area is normally exempt from the need for building regulations approval.
This is provided that glazing and any fixed electrical installations comply with the appropriate sections of building regulations.
To find out more about the building regulations for porches, visit Planning Portal.

If you want formal confirmation that the existing use of a building is lawful for planning purposes, or that your proposed development does not require planning permission, you can apply for a Lawful Development Certificate(LDC). An LDC can be useful in situations where you need assurance that a particular use, operation, or development is lawful under planning legislation.
Read more about Lawful Development Certificates.
Applications for a Lawful Development Certificate can be submitted online to your local council using Planning Portal. You must include enough detail and evidence to support your case; if the information is insufficient, your application may be refused.
In most cases neither planning permission nor building control approval are required for replacing grass with artificial grass. If you live in a protected areas such as a conservation area, or listed building, it is best practice to contact your local planning authority to check whether any consents are required.
