The Building Project That'll Ruin You Financially

“Budget does not mean your build cost.” Matt drops that early, and it should be printed on every set of concept plans. In this episode of The Mindful Builder Podcast, Matt and Hamish sit down with Brad McEwan from Sanford Buildco for a blunt chat about project feasibility and why so many custom home builds in Australia blow out financially. If you’re a homeowner, builder, or designer trying to avoid budget shock, this one will save you a lot of pain.

We talk about the gap between a client’s budget and the reality of what the design actually costs, plus the hidden “other costs” that show up before you even start building. Think site works, services, reports, permits, access, and all the stuff that never makes it into the Instagram floor plan tour. Brad also breaks down how “small” choices like garages, alfrescos, tiles, and finishes can swing the price wildly depending on what you pick and how it’s installed.

If you’ve ever wondered how to pressure test a budget early, what a feasibility estimate is actually for, or what to ask a builder before you spend big on documentation, we cover it in plain language. Keywords: project feasibility, construction budget, build cost vs budget, custom home build Australia, building costs 2026, cost overruns, variations, architect budget, builder advice, pre construction process.
