My DLF Garden Estate flat feels smaller, what did I miss?

Honestly, I thought I had everything sorted when I got possession of my flat at DLF Garden Estate last month. But living here, I realized something important about carpet area. Builders often show you super built-up, but actual usable space for furniture and daily movement, especially in a 3BHK, feels tighter than expected. My 1600 sqft unit, after all the walls and common areas, feels more like a 1200 sqft flat. Did anyone else notice this with their units here? It's not just about the numbers on paper, but how the layout actually works for daily life. Like, my living room feels a bit cramped after placing a decent sofa. It's a small detail but makes a big difference. Hope this helps other potential buyers to really check the floor plans minutely during site visits. Kya aapko bhi aisa laga?
