The ARKITECNA Construction Estimator (/estimator/construction) calculates preliminary physical construction, renovation, swimming pool, landscape, external works, contractor margins, VAT, and PBG/SLF building permit budgets in Bali and Indonesia in Indonesian Rupiah (IDR, 2026 values). Developed by ARKITECNA / DGJ Architects (Trieste, Italy · Bali, Indonesia · Hong Kong · Dubai, UAE).

1. Five New-Construction Quality Tiers (IDR/m²)

Direct building works for new construction in Bali are calculated across 5 specification tiers from constructionEstimatorConfig.js:

  • Base: IDR 6–8 M / m²
  • Mid: IDR 8–10 M / m²
  • Premium: IDR 10–12,4 M / m²
  • Luxury: IDR 12–15 M / m²

Q&A

How much does it cost per square metre to build a new villa in Bali in 2026?

In the ARKITECNA Bali Construction Estimator (/estimator/construction), direct new-construction costs (before margins, VAT, and permits) are structured into five specification tiers in Indonesian Rupiah (IDR, 2026 values): Base at IDR 6–8 Million/m², Mid at IDR 8–10 Million/m², Premium at IDR 10–12,4 Million/m², Luxury at IDR 12–15 Million/m², and Ultra-Luxury at IDR 20–30 Million/m².

What is the complete step-by-step cost breakdown for a 250 m² Mid-tier villa in Bali with a 30 m² pool?

Using official verification benchmark Test A (250 m² new construction, Mid tier at IDR 8–10 M/m², 30 m² swimming pool, Tropical villa garden landscape, and all 4 PBG/SLF permit groups): Direct building works = IDR 2.000,00 – 2.500,00 M; Swimming pool (30 m² × IDR 4–7,5 M) = IDR 120,00 – 225,00 M; Landscape = IDR 30,00 – 120,00 M; Contractor margins (22–37%) = IDR 473,00 – 1.052,65 M; Indonesian VAT (12%) = IDR 314,76 – 467,72 M; PBG/SLF permits = IDR 48,00 – 75,00 M. The total all-in estimated budget is IDR 2.985,76 – 4.440,37 Million (equivalent to IDR 11,94 – 17,76 Million/m² all-in).

Which renovation works and prices are available in the Bali Construction Estimator?

The calculator provides six selectable renovation packages in IDR (2026 values): 1) Full villa renovation: IDR 200–800 M (lump sum); 2) Kitchen remodel: IDR 40–150 M (lump sum); 3) Bathroom remodel: IDR 25–60 M (lump sum); 4) Flooring replacement: IDR 150.000–800.000 per m² (multiplied by project area); 5) Interior & exterior repainting: IDR 10–30 M (lump sum); and 6) Pool resurfacing & equipment: IDR 30–120 M (lump sum).

How are swimming pool, tropical landscaping, and external site works priced in Bali?

A swimming pool is estimated at IDR 4–7,5 Million per m² of water surface. Tropical landscaping is based on a 150 m² reference garden and scaled proportionally by project area across three tiers: Essential (IDR 15–25 M), Tropical villa garden (IDR 30–120 M), and Extended resort landscape (IDR 50–300 M). External works are priced at IDR 1 M per linear metre for boundary walls, IDR 1–2 M per m² for access roads/driveways, and IDR 10 M per 100 m² for land fill and grading.

How are contractor margins and Indonesian VAT calculated on Bali construction budgets?

Contractor margins are applied to total direct works (building + renovation + pool + landscape + external works) and total 22–37%: Preliminaries (5–7%), Contractor overheads & profit (7–10%), and Contingency (10–20%). Indonesian VAT of 12% is then calculated on the sum of direct works plus contractor margins.

What PBG and SLF building permit fees are included in the Bali Construction Estimator?

When all four selectable permit items are checked, total PBG/SLF permit fees equal IDR 48–75 Million (not subject to VAT). The four selectable items are PE2 Soil investigation & sondir test (IDR 18–30 M), PE4 Architectural & structural drawings for PBG (IDR 4–8 M), PE5 PBG official retribusi / government fee (IDR 24–32 M), and PE10 SLF feasibility certificate (IDR 2–5 M), while additional administrative permit lines (PE1, PE3, PE6, PE7, PE8, PE9, PE11) are automatically included in the total check when permits are selected.

What costs are excluded from the Bali Construction Estimator?

As explicitly stated in the calculator, the construction estimate excludes three items that are quoted separately: land, design fees, and furniture. Specifically, architectural and MEP design fees are estimated on /estimator, and interior furniture / FF&E packages are estimated on /estimator/furniture.

Which currency and geographical market does the Construction Estimator cover?

The Construction Estimator (/estimator/construction) covers exclusively Indonesia / Bali, with all rates, unit prices, and totals denominated in Indonesian Rupiah (IDR, 2026 values).
