Bill of Quantities Generator for Australian Home Builds

Most Australian build-cost calculators land on one $/m² number after a handful of dropdowns — location, size, finish tier. That's a useful ballpark, but it skips the part a licensed builder actually prices against: how many bricks clad the veneer, how much timber or steel frames the internal structure, how the roof shape changes covering area. This generator builds that takeoff first.

Brick veneer — a timber or light-gauge steel frame carrying the load, single-skin brick as cladding only — is the real dominant method across most of Australia, distinct from UK-style double-skin cavity wall or US wood-frame-with-siding. The quantities here use a real single-skin coefficient (roughly 48-50 bricks/m²) rather than treating 'brick house' as one generic category.

Two real Australian cost drivers change actual specification, not just price: Bushfire Attack Level (BAL) zoning and reactive-clay soil classification. Both are decisions you make when pricing your own rate for the affected lines — this tool surfaces where they apply rather than folding them into a hidden multiplier.
