“4. The Appellant has constructed a first floor rear extension which does not extend beyond what was believed to be the original single storey lean to and a single storey extension of 4m depth from the outer wall of the lean to. There is no first floor extension above this 4m extension and the LPA has acknowledged that these works were carried out in good faith being permitted development … …….. 6. …………….On land within an AONB, the enlarged part of the dwelling house may, if it is only one storey, extend up to 4m beyond the wall of the “original” dwelling house and may be up to 4m in height. The “enlarged part” which is 4m in depth is only a single storey extension extending from the rear wall of the original lean to and therefore is permitted development. It does not have a floor above it and so cannot be considered to be a two storey extension – see attached correspondence with the Council and the planning lawyer’s advice given to Council (Doc 3). 7. With regard to the first floor extension, this is directly above the original lean to and does not extend beyond the rear wall of the original lean to as outlined in the red line drawing. Article 2(c) of the Schedule 2 to theTown and Country Planning General Permitted Development Order 1995 (sic) provides that an enlargement of more than one storey should not extend beyond the rear wall of the “original dwellinghouse” and therefore is permitted development. ………………. ……………. 10. The Appellant submits, for the reasons set out at paragraphs 7-9 above, that the extension which has been constructed benefits from Permitted Development rights or alternatively that the majority of the development benefits from permitted development rights and that what has been constructed is not materially different from that which would be designated as permitted development and therefore planning permission should be granted. 11. In addition to the rear Permitted Development rights, the property also benefits from Permitted Development rights which allow the Appellant to construct a substantial two storey extension to the front of the property, as shown at Doc 7. ……………….. 13. If planning permission is granted for the extension which has been constructed the Appellant would be prepared to forego his right to exercise his permitted development rights to the front of the building. …………….. ……………. 15. In addition the Appellant submits that the planning permission should be granted as what has been constructed is significantly more appropriate to the Green Belt than what he could construct to the front and rear of the property under permitted development rights which is the fall back position. …………….”
“on designated land, no permitted development for rear extensions of more than one storey 3.”

“25 The fallback argument is in truth no more or less than an approach to material considerations in circumstances where there are, or may be, the opportunity to use land in a particular way, the effects of which will need to be taken into account by the decision-maker. That involves a two-stage approach. The first stage of that approach is to decide whether or not the way in which the land may be developed is a matter which amounts to a material consideration. It will amount to a material consideration on the authorities, in my view, where there is a greater than theoretical possibility that that development might take place. It could be development for which there is already planning permission, or it could be development that is already in situ. It can also be development which by virtue of the operation of legal entitlements, such as the General Permitted Development Order, could take place. 26 Once the question of whether or not it is material to the decision has been concluded, applying that threshold of theoretical possibility, the question which then arises for the decision-maker is as to what weight should be attached to it. The weight which might be attached to it will vary materially from case to case and will be particularly fact sensitive. Issues that the decision-maker will wish no doubt to bear in mind are as set out in the authorities I have alluded to above such as the extent of the prospect that that use will occur. Allied to that will be a consideration of the scale of the harm which would arise. Those factors will all then form part of the overall judgment as to whether or not permission should be granted. It may be the case that development that has less harm than that which is being contemplated by the application is material applying the first threshold, and then needs to be taken into account and weight given to it.”
“…. Whatever the depth of the lean-to, the extension at first floor level was built out from the (first floor) rear wall and results in the enlarged part of the dwellinghouse having more than one storey. It is thus not permitted development.”
