This application is proposed by Grŵp Amos Cymru Cyf, who are seeking to renovate both Mona Inn and Mona Isaf, along with the conversion of the associated outbuildings, into open-market residential units. These buildings are designated heritage assets, which are Grade II and Grade II* listed respectively, and have fallen into disrepair following years of neglect. Recent emergency works were undertaken to repair and replace part of the roof of the Mona Inn, which was in critical condition, and this proposal seeks to ensure the long-term future of these buildings through a well-considered, viable scheme which adopts a conservation-led approach.

The development seeks to renovate the existing buildings and will locate all new residential units within these existing buildings, which have all been subject to structural surveys and deemed suitable for conversion. These buildings have also been subject to ecological surveys and a heritage impact assessment (HIS), and the proposal has been deemed to be suitable. Physical works will be limited only to those necessary, and new external materials will seek to match existing finishes.

The application is accompanied by a landscaping scheme which will provide significant biodiversity enhancement, along with a sustainable drainage strategy which adopts water conservation principles and will deal with both surface and foul water drainage.
