Select the "Explore" icon on the Town Map, and keep exploring until you don't find anything, then pay attention to the text hints that you're given - they'll point the way to the burning building.
Sorry, I don't know what you mean by "noisy place" or "dustbin" - neither of those are in CK. To advance Roxy's storyline all you need is the AURA power and then to explore the burning building. I think it's the first floor you need to check.
