The extension, which would create an additional 47 rooms, has been put to Edinburgh City in a planning proposal. The hotel, which currently offers 197-rooms, would also see a new kitchen and dining space added as well as back of house facilities if the plans are approved.
In the proposal 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.”
