KCC Engineers Enclave: Who thinks carpet area is fair?

Does anyone actually feel KCC Engineers Enclave's carpet area is good value for money? Honestly, the brochures show decent layouts, but I'm worried about the actual usable space. My parents keep saying 'bigger is better' for a first home, and these units feel a bit cramped for the price. Is it just me, or do you really get less usable area than advertised for ₹40L? Feels like we're paying for walls. Change my mind.
