In many cities in the UK, space is at a premium, which means you can’t add an extension to the rear or side of your property. So another option worth considering to create additional space is a cellar or a basement conversion

If you have a basement you already have a room to work with, so upgrading this space will be less expensive than creating an above-ground extension. Plus, it's the perfect way to add value to your home with a new bedroom or social space.
