The City Council has granted planning permission to Carra Shore Hotel for the redevelopment, conservation, and refurbishment of numbers 31, 32, and 33, South Terrace, in the city centre.
The buildings will be converted into a new 103-bedroom hotel, as part of the project.
They are protected structures requiring conservation.
A five-floor over-ground-floor and lower-ground-floor annex at the back of the development will connect to the existing buildings by a glazed link at ground floor.
The plans also include an landscaped courtyard and green roof.
