TVS Emerald Altura: Is their 3BHK carpet area efficient?

Been looking for a bigger 3BHK for my growing family for months now. My tip for TVS Emerald Altura: don't just see the brochure's BHK count. Really deep-dive into the carpet area efficiency and layout. For kids, usable space matters most, not just total sqft. Is their layout really practical for daily living, ya sirf on paper acha hai? Any parents agree?
