Proposals submitted to the City of Edinburgh Council include a nine-story extension to the rear of the building, which would take the property to 242 bedrooms if approved.

In the application, the developers said: “The site is located within a mixed-use area and the change of use would not result in any materially detrimental effects on living conditions of nearby residents.

“The proposed extension to the existing hotel is in keeping with the surrounding area and the materials proposed for both the new and existing development would improve its appearance, especially when considered in the context of the surrounding conservation area and World Heritage site.

“Overall, the proposed development would provide high-quality accommodation in an appropriate location which would support the role of the city centre and the local economy.”

The developers added: “The proposed extension to the existing hotel is considered to be appropriate and it presents a good opportunity to increase visitor accommodation in a highly accessible location.

“The proposed design is in keeping with the surrounding area, and the replacement of cladding on the existing building would improve its appearance.

“In addition, the extension largely falls within the envelope of the previously approved scheme. Therefore, we respectfully recommend that planning permission should be granted.”

If approved, seven car parking spaces will make way for the extension – leaving a total of 15 spaces for hotel guests in the courtyard.
