Which way is up?

Which is the correct way to deal with prior approval Class AA upward extensions? Is it in line with the case we reported in Words on the street (DCS Number 400-031-261) in which an inspector ruled that the council’s concern about the impact on the street scene was not relevant, or is it line with a slightly more recent decision (DCS Number 400-031-906) in which the inspector found that it was?

In the more recent case (we’re only talking about a matter of weeks, here) the inspector decided that an additional storey on a bungalow in a street characterised by bungalows and chalet properties would appear incongruous. 

Under ‘Conditions’ AA.2 states that ….(3) The conditions in this sub-paragraph are as follows….(a) before beginning the development, the developer must apply to the local planning authority for prior approval as to…(ii) the external appearance of the dwellinghouse, including the design and architectural features of—(aa) the principal elevation of the dwellinghouse. 

Seems to us you could argue it either way so, sorry, we honestly don’t know. 

The permitted development classes are set out at section 4.342 of DCP Online.
