This is for an office building known as Mill House, located at 8 Mill Street in Southwark. The change involves moving away from its current use as office space (Class E) and transforming it into hotel accommodation (Class C1). The building is not empty and is currently working as office space. This change would mean the office space would be completely replaced by the new hotel with no remnants of its past use. This means all current office space will be converted into hotel use, with no addition or loss of space.
