The hotel, which currently has 20 rooms, is set for an additional 32 rooms, a new lift to improve disabled access and on-site staff housing, after plans were approved by Aberdeenshire Council.
Dating back to the 1970s, the hotel was originally a popular shooters lodge and was fully refurbished in 2008 when its current owners took charge.
Recently, the ground floor of the hotel underwent an “extensive” refurbishment in order to “keep in line with modern trends.
Score Group plc applied to Aberdeenshire Council, on behalf of Quitie Limited.
According to a report by the local authority’s infrastructure boss Stephen Archer cited by the Evening Express, the development was approved due to the “negligible impact” on the surrounding area.
He said: “The proposed extension would be to an existing building and within its curtilage, within the coastal zone.
“No alternative location outwith the coastal zone would be appropriate due to this being an extension and the siting on an existing area of hardstanding means there would be a negligible impact on the coastal location.”
