Here’s what you need to know:
You don't need planning permission for internal works to a house such as moving walls or changing finishes.
Key areas to watch out for:
Don't do anything which changes the core use of the house e.g. start using it as a commercial premises - this would require planning permission.
Knocking 2 houses together to use as one, or subdividing a house into several separate apartments counts as a change of use - these scenarios would require planning permission.
Requirements are different for protected structures - altering the internal walls, floors, ceilings and finishes may require planning permission.
Some other important things to consider when planning a build:
Anything you build (regardless of planning) will have to comply with the Building Regulations. These govern everything from energy performance to the size of window openings.
Depending on the size and duration of your project, you may need to appoint project supervisors to ensure your build goes safely.
Consider using the services of a registered Architect, Engineer or Surveyor who will be familiar with the planning system.
