But there is something being built in their "backyard" and it was modified in response to their complaints, although I don't know anything about the supposed "bullying" that happened. In my humble opinion, it's sufficiently urban and appropriate for the site given the number of floors and similarity of scale to other streets in the vicinity.
I'm not clear on how negative feedback on a design and demands for modifications in response is claiming property rights on property that's not yours. If they proposed a couple vinyl clad raised ranch houses and aB came out with pitchforks, wouldn't it be a similar case? The argument would be for design mods to be made to achieve something believed to be a better design.
