Every square foot matters in real estate. FAR determines how much you can build, GFA dictates what gets approved, and BUA influences what you can sell. A higher FAR boosts development potential, a well-optimized GFA eases approvals, and a clear BUA ensures customer trust. Developers who strategically align these three elements improve efficiency, increase saleable area, and maximize returns. Misjudging any of them can lead to cost overruns or reduced margins. Understanding how they interplay allows smarter pricing, better ROI forecasting, and streamlined project execution from concept to completion.
