Architects battle it out everyday for their visions of the built environment to be made reality. These battles produce areas which are saturated with architectural language as each architect produces and designs forms and idioms that attempt to stand out on their own rather then sing together.

... which in my view is currently very true of the recent development of ego towers in the city.
