Owner-Builder Companion

Build Roadmap

Five stages, matched to the real NSW critical stage inspections a Principal Certifier signs off on. Stage 0 is open for everyone — the rest unlock with the full pack.

A compliance toolkit, not a replacement for the mandatory NSW Owner-Builder Course (10290NAT).

Before You Start

Council, certifier, and standards basics before you break ground.

01

Footings & Slab

Critical stage inspection #1, and locking in drainage before the slab is down.

02

Frame

Critical stage inspection #2, and where trade coordination most commonly breaks down.

03

Lock-up

Critical stage inspection #3, and the neighbour-dispute mistake that's easy to avoid.

04

Fit-out / Final

The inspection that gates your Occupation Certificate, and where to spend vs. DIY.
