The work, which represents £300,000 of a £750,000 investment in the venue, has seen the hotel bar extended to three times its original size, doubling its covers from 45 to 90.
Outside, a new terrace has been created for the hotel where a wood-fired oven has been installed.
The latest phase in the re-development also included the refurbishment of the hotel’s restaurant and reception area.
The food and drink offer at the Banchory Lodge Hotel has also been revamped with the introduction of a new menu which is said to focus on fresh, seasonal, locally-sourced produce with options including a seafood platter and char-grilled meat section.
A new wine list has also been introduced offering a choice of over 30 wines and Champagnes.
Robbie Mitchell, general manager at the hotel, said he is “very excited that the third phase of our refurbishment is now complete”.
“We’ve worked hard to deliver a venue for Deeside that is as much for the locals as it is for guests further afield,” he said.
“Whether coming to dine or drink, all guests will experience a friendly welcome and the highest standards.
“We’ve restored and added to the building and grounds to make sure that Banchory Lodge Hotel becomes an unbeatable and memorable choice for visitors.
“There will be something for everyone.”
The Banchory Lodge Hotel was purchased by current owners Wilson Anderson and Carol Fowler in 2012.
