So, this is my first proper night-render.
Any thoughts on how to kill noise inside the windows?
And would also be nice to make it rain. Would it be better to post that or is there a proper way to render rain?

NOISE!!!

what you have there in rooms? Area Lights?

luminous boxes.

I think the best idea is put square lumi on the ceiling in centre room. It will bright whole room. Colour must be very warm.
