What people actually build
Every one of 423,148 development applications lodged in NSW since 2019, broken down by type of work — 274 distinct kinds, from a new dwelling to a farm shed. Each row is what that work typically costs and how many homes it delivers. Sort any column.

Cost of works is the applicant's own estimate as lodged, so this reports the median rather than a total: the feed contains keying errors large enough to make sums meaningless — the biggest is $1,111,111,111,111 against alterations to a house, and 22 applications state a cost above $1,000,000,000 and are excluded here. Types with fewer than 20 applications are left out, because a median of a handful is noise. Source: NSW Planning Portal — Online DA open API, Creative Commons Attribution 4.0.
