A building consent is usually not required to construct, alter or remove an internal wall or doorway.
Planning permission for doors is typically not required when replacing existing doors with similar ones or making minor alterations. However, you may need permission for significant changes, such as relocating your front door, creating new openings, or modifying doors in listed buildings or conservation areas.
If you're adding a new window or door or changing the size of an existing one, then you are changing structure. The reason you need a permit for this is to ensure the continued safety of people in the home when structural changes are made. Why not just get a permit?
As a general rule, anything which changes the structure of the property will need building control approval and to obtain this you'll need technical information from a structural engineer.
As a general rule, you don't need planning permission for removing internal walls. But, if you are renovating a listed building, then you need consent for any external or internal work. You may also need your council to approve the work if it is load-bearing.
The average cost of knocking down an internal wall is around £1,000-£2,500. It is worth noting that there are several costs involved with this type of work. Why would such a wall be removed anyway? Removing a load bearing wall is a fantastic way to free up more space in a room, or even combine two rooms into one.
Can I change the internal layout after planning permission? Most internal changes don't need you to secure planning permission. This also includes removing an internal wall. However, listed buildings work a little differently and require you to seek approval from your local authority.
Unless you live in a listed building, planning permission will not be required, but it is still necessary to let Building Control know and they will, in all likelihood want to send a building inspector out (particularly if it's a loadbearing wall you are dealing with).
Furthermore, if any modifications do not comply with local building regulations, you may face unpleasant consequences further down the line and not be able to sell the property. In summary, if you're planning on knocking down an internal wall, it's not just recommended, but essential, to involve a structural engineer.
You'll likely need a permit since this project may require soil grading to avoid drainage issues. Repairing your floor may be more cost-efficient than replacing it if grading is necessary. No permit may be required to hang drywall on exposed wooden wall studs in your garage.
Hanging or installing a door isn't as difficult as it may seem. Replacing an existing door is easy if the new door core is the same size. Installing a door in a new partition wall is also very easy if you buy a prehung door so you don't have to build the door frame yourself.
Various state regulations require contractors to pull permits. California, for example, mandates that anyone who works on your home must be licensed by the Contractors State Licensing Board (CSLB) if the project is over $500.

You do not normally need planning permission to change your windows and doors as this is considered 'permitted development' for dwelling houses.
Any domestic dwelling that is three storeys high or over must have fire doors installed. All doors between habitable rooms and stairwells must be fire doors. If there is an internal garage or a converted loft, these areas also need to have fire doors installed as entryways to the house.
Generally, you don't need to apply for planning permission for internal alterations, including removing internal walls. However, if you live in a listed building, you will need a listed building consent for any significant works, internal or external.
You should consult directly for accurate rates. For hourly rates, expect to pay between £90 and £200. A basic project usually ranges from £350 to £450, while complex projects can reach up to £10,000 in cost. For a detailed structural engineer report, costmay range from £500 to £2,000.
However, you do need building regulations permissions. This is necessary for any door upgrades you are planning, including any slimline doors you are adding to your home. Any door upgrade to listed buildings or those in conservation areas will need planning permission, so speak to your local authority to find out more.
