As somebody said previously, these matters should've been addressed in the planning stage. I am stunned that we are not allowed to design something because it overlooks in someone's garden, but Tate got its permission for an actual viewing deck towards residential areas!! I found it outrageous then as I find it now. As much as I like the new addition to Tate, this shouldn't have happened.
But also, in planning stages the residents have had their time to voice their opinions - if they weren't vocal then, now is too late.
