The site not only lay in a former walled garden within the conservation area but was also surrounded by listed buildings and in the AONB.  A previous application for a more conventional above ground dwelling was refused and dismissed on appeal but the appeal decision provided some degree of support for the proposal and left the door open for a further amended application.  The result was this extremely exciting design that that not only created a completely one off design but also overcame the reasons the Planning Inspector dismissed the appeal.  As such the planning officer was able to grant planning permission under delegated powers.
