What Affects Your Final Quote

Five unseen details beyond the sliders.

The calculator gives baseline, per-square-foot guesses. After a complimentary site visit, your final, tailored quote will take into account the particular site circumstances listed below.

  • Ground & Foundation RealitiesSoil testing can shift the footing depth and also tweak the reinforcement requirements, especially when the land is reclaimed or basically low-lying
  • Access & Plot DynamicsWhen the approach roads feel narrow, the costs for moving materials go up, while plots that are irregular or kind of cornered can quietly reduce FAR efficiency, because the geometry just doesn't cooperate
  • Height & Structural ClassOnce you move past G+3, the frame design has to be stiffer, and that changes the concrete and steel ratio per square foot, which people don't always notice at first
  • Interior Tier VariancesEven if the finish package sounds identical on paper, differences show up in marble batch selection, hardware brands, and the lighting specifications; these little things redirect internal costs
  • Location LogisticsRunning through four active site offices helps keep transport overhead steady inside certain zones, yet external locations usually bring a small delivery premium; it adds up over time

    Common Questions

    About the estimate, answered directly.

    Is GST always included in the total shown?
    Yes — the 5% GST line is always calculated and added into the Total Estimate above. Nothing is added later that isn't already visible on this page.
    Can I mix package tiers, like Signature construction with a Smart interior?
    Yes — the three dropdowns are independent. Any combination of Construction, Architecture and Interior tier is valid and recalculates instantly.
    How close is this to my actual final quote?
    Typically within 5–8%, before the five site-specific factors above are confirmed. A project engineer finalises the exact number after a site visit and soil report.
    What's excluded from this number?
    CMDA/DTCP approval fees, EB & water connection deposits, borewell and compound wall — all charged separately and confirmed upfront, never buried into a "miscellaneous" line.
    Can I lock in today's rate?
    Yes — package rates are locked for 30 days from the date you sign a construction agreement, regardless of material price movement during your build.
