Every job starts with a site measure and a conversation about what you want and what it's likely to cost. From there, two ways to run it — depending on the size of the job.
A kitchen, a bathroom, a deck, a single-room extension.
Usually no DA — just the certifier.
Whole-house renovations, raises and extensions, commercial fit-outs.
Full design and documentation, through to approvals.
Quoted per stage, so you know the cost before each step starts.
The person who sketches your idea is the person who draws it for the builder. Nothing gets handed down the line.
I'm not a certifier, engineer or town planner — but I've got good ones that I can put you in touch with, and I coordinate them for you.
