Super area games: The real cost trap in Sector 150?

Did a site visit to Ajay Enterprises' new project in Sector 150. Honestly, builders ka super area vs. carpet area game ab bhi chal raha hai. Matlab, 3BHK dikha ke 2BHK jaisa feel dete hain. As an investor, should I focus on spot discounts ya payment plan mein leverage milega? Construction-linked plans worth it yahan? Change my mind.
