The right configuration is not only about buying more space. It is about how you expect the home to work over the years you plan to live there.
Think about the rooms you need now
Consider sleeping spaces, work-from-home needs, visiting family, storage and how often an extra room would have a real purpose.
Think about how your household may change
If your family or working routine may change, compare how flexible each configuration feels rather than deciding only from the brochure label.
Compare the actual floor plans
A well-planned 2 BHK can sometimes suit a family better than a poorly planned larger home. Compare room dimensions, circulation and usable spaces before deciding.
