Rebuild market

28% of approvals are new builds or demolitions, so knock-down-rebuild is a genuine slice here, not just extensions.

Big-ticket jobs

the typical $152k approval is about 21% of the $725k median home, these are substantial transformations, not cosmetic touch-ups.

Lifestyle spend

23% of approvals are pools, decks and fencing, a discretionary-spend signal for pool, landscape and fencing trades.
