Ansal Aastha owners, actual carpet area ka kya scene hai?

Honestly, I didn't realize how much carpet area matters until now. Ansal Aastha Mig Zone mein just shift hua, but lag raha actual usable space thoda kam hai. Builder ne jo plan dikhaya tha, usse toh kaafi different feel ho raha hai. Does this affect per sqft value ya rental potential in the long run? Koi aur experience share karega? It's a big investment, aur ab thoda nervous feel kar raha hoon.
