The Meruelo family will have to wait until January to know if the Miami Beach Historic Preservation Board approves its plan to almost double the size of the historic Deauville Hotel.

The preservation board liked the proposed 412-room hotel tower the family wants to build next to the iconic 56-year-old building at 6701 Collins Ave. But the board said Tuesday before approving any new construction it wants to make sure the existing hotel is being properly maintained under “historic preservation” standards.
