Mezzanine Floor Planning Permission
Unless prohibited by a condition attached to a previous consent, you will not require planning permission, as long as the changes are internal.
The Government has, however, been trying to control the expansion of retail floor space in out-of-town developments, and has brought in legislation requiring planning permission for floors above 200m².
Nonetheless, it is permitted to add several floors, each just below the 200mē limit without requiring planning consent.
