Yes, you may need permissions to change a boundary wall, depending on the type of work you plan to carry out. The permissions and regulations vary depending on the type of wall, its location, and the proposed changes. Here are some of the permissions and regulations you need to consider:
Planning Permission: You may need planning permission if the proposed changes affect the height, location, or appearance of the wall. You can check with your local planning authority to determine if you need planning permission.
Building Regulations Approval: You may need building regulations approval if the proposed changes affect the structural integrity of the wall or if the wall is a party wall. Building regulations approval ensures that the work meets the necessary safety and structural requirements.
Party Wall Agreement: You need a party wall agreement if the wall is a shared structure between you and your neighbor. A party wall agreement outlines the rights and obligations of each party concerning the shared structure.
