The Royal Dublin Hotel is to undertake the €8 million restoration of the last surviving Georgian townhouse on Upper O'Connell Street which it will eventually lease or dispose of as an office complex or corporate headquarters. To make it suitable for modern office requirements, Number 42 will be separated from the hotel - it's ground floor has been in use as part of the hotel foyer - and a glazed link to its rear will connect it to a third generation office block which, remarkably, will encase another historic protected building, O'Connell Hall. Built in the mid 18th century, the four-storey over basement townhouse is the last surviving example, on what was originally a residential street, of the original Sackville Mall Mansion.
