GFA vs BUA vs NSA Efficiency Calculator
See the gap between what you're permitted to build (GFA), what you actually pour concrete for (BUA), and what you can put on the price list (NSA). UAE benchmarks, parking-strategy aware.
A common cause of broken Dubai pro-formas: the investor budgets against GFA, the contractor builds BUA, and the agent sells NSA. The three differ by 25–50%. Move the controls — see the leakage.
5–8% of your efficiency ratio is recoverable with Design Management.
Poor architectural coordination quietly drops the efficiency ratio by 5–8%, costing millions in lost sellable space and bloated construction cost. Through rigorous Design Management and Value Engineering, INGEX rationalises structural cores, optimises MEP routing, and minimises dead space to maximise your net sellable area.

We benchmark your current scheme against UAE peer projects, identify dead-space concentrations, and quantify the sellable-area uplift available through targeted design intervention. Held under NDA.
High-level estimates based on typical UAE real-estate benchmarks. Actual areas are strictly subject to final architectural design, authority regulations (DM, DDA, Trakhees, RERA) and specific plot constraints. Contact INGEX for a precise design efficiency audit.
