It can eventually be improved to look both more unique and fitting, right now the exterior is essentially the same as it always was, except with a perimeter of hedge to allow it to blend with grass, and also retain that little bit of familiarity due to Tony Montana's house being there previously. Yes it is far from ideal, but I don't see it as a huge clash in the way that is being made out, if anything the Studios are meant to be something of a quirk.
I would also place more importance on the location of the building over the size of it.
