Do I need planning permission to convert my garage into a workshop?
If the garage will remain in domestic use - for example, as a personal hobby or home workshop - then planning permission is typically not required.
However, it’s important to check whether there are any planning conditions, covenants, or restrictions attached to your property or the garage itself that may limit or prevent conversion.
