Navigating the Financial Blueprint of Residential Construction
Understanding cost allocation allows homeowners to manage expenditures strategically. Inexperienced homebuilders frequently overspend on preliminary civil structures, leaving insufficient budget for essential daily-touch finishes like tiles, joinery, and sanitary fixtures. Below is the realistic percentage allocation for a modern turnkey home.
| Category | % Share | Key Inclusions |
|---|---|---|
| 1. Civil Structure (Gray Structure) | 42% – 46% | Excavation, footings, RCC framework, steel, cement, bricks, sand, aggregates, and plastering. |
| 2. Finishing Works | 28% – 32% | Flooring tiles/granite, interior/exterior painting, teak main door, flush doors, UPVC windows, and stair railings. |
| 3. MEP Services (Plumbing & Electrical) | 14% – 16% | CPVC/PVC pipe networks, bathroom fixtures, CP taps, modular switches, fire-retardant wiring, and distribution boards. |
| 4. Planning, Approvals & Contingency | 8% – 10% | Architectural/structural design fees, municipal building permits, electricity board charges, and unforeseen site contingencies. |
