17 In considering the application with regard to the principles in Progress and Securities, I accept Mr Hall's submission that the circumstances have changed since the original approval. The two-storey development, setback and use of the upstairs rooms at No. 22 is different to what existed at the time of the original approval. While I accept that this was done by the McCarthy's to seek to minimise the impact of the development at No. 20 on their outdoor living space, it is a change in circumstances that is sufficient to mean that the impact of the terrace on No. 22 can be reassessed. It is obvious that the impact of the proposed roof terrace may be different depending upon what it adjoins.
18 In examining the impacts of this proposal, I find that the view from the deck over No. 22, even without the privacy screen, is limited. With the privacy screen there is no view over the adjoining property. The additional bulk that the privacy screen adds to the development is negligible. Views to this part of the garage from No 22 are largely restricted and the increase in the height of the balustrade with an opaque glass screen will not materially add to the bulk of the building. Particularly when the overall bulk of the development is considered, which Mr McCarthy understandably finds to be oppressive.
