The 4 Biggest Cost Drivers in Waikato Construction
1. Section Topography & Ground
Sloping sites, poor peat soil, or high water tables require engineered concrete pile foundations or extensive retaining walls.
2. Roof Form & Span Geometry
Simple hip roofs are cost-effective; multi-pitched architectural pavilions and cantilevered steel spans require custom structural engineering.
3. Cladding Systems
Brick veneer is economical; hand-charred Japanese larch, imported stone, and standing seam zinc involve specialised artisan trades.
4. Glazing & Joinery Ratios
Standard aluminium versus oversized floor-to-ceiling thermally broken low-E argon double glazed suites.
