Loft conversions are a popular way to add space and value to a home in the UK. Here's a quick overview of what to expect in our loft conversion planning permission guide:
You may not need planning permission for a loft conversion if it falls under Permitted Development Rights, which apply to most houses with certain volume and design restrictions.
