ATS Le Grandiose: Carpet area efficiency ka real deal?

ATS Le Grandiose Phase I mein carpet area aur super built-up ka difference bohot feel hua site visit pe. Is it just me, ya actual living space thoda cramped lagta hai compared to brochure? Also, maintenance charges kitne aate hain monthly? Sunte hain amenities ka cost kaafi add ho jaata hai. Koi actual figures bata sakta hai?
