Budget estimate

$4,000,000 – $6,000,000

Based on the size (≈12,500 SF) and the historic‑preservation nature of the project, renovation costs in Hawaii typically range from $300 to $500 per square foot, especially when hazardous‑material abatement and specialty finishes are required. That yields an estimated contract value of roughly $3.8 M to $6.3 M. Assuming the contractor’s profit margin (including overhead) falls between 8 % and 12 %, the net budget to the contractor would be in the $4 M‑$6 M range. Factors influencing the final amount include the extent of unforeseen site conditions, the amount of asbestos/lead remediation needed, and any change orders arising from historic‑treatment requirements.
