I'm considering converting my derelict stable block located in the Cotswold AONB (not listed). It is my understanding that as it is not classed as an agricultural building, plus some structural alterations may be required I cannot proceed through Class R conversion, therefore I would need to proceed with a full planning application.
May I have some advice as to whether by converting the stable it would effectively become a 'new' dwelling and therefore have to comply with the countless requirements for a new build, energy efficiency (possible solar PV, air-souce heat pump), attenuation tanks, electric vehicle charging, mini sewage treatment plant, BNG, etc. etc.? Or would I be able to avoid some of this?
