Why the Builder Who Disrupted His Own Industry Might Just Fix Australia's Construction Crisis — And What BuildBuddy Means for the Rest of Us

The construction industry in Australia is truly broken. It is the slow, grinding, productivity-going-backwards-for-a-decade or more way broken. It’s far more dangerous than a sudden crash, because we've all just accepted it as normal, while we all complain about the lack of new housing.

So when I sat down with Danny Assabgy on The Proptech Podcast, I was expecting a good chat about his platform, BuildBuddy. What I got instead was a masterclass in what happens when someone with deep industry knowledge has the courage to blow up their own business model.

Danny is the CEO of Hudson Homes — a major home builder that was Australian Builder of the Year in 2023 and NSW Builder of the Year in 2024. This is not some outsider lobbing grenades at the building industry from a safe distance. This is the guy who has his photo, phone number, and email in every single Hudson Homes display home because he wants customers to call him when things go wrong.

And that's exactly how BuildBuddy was born. Four years ago, a customer rang Danny and said, "Mate, I can do a better job building my house than what you can." Danny's initial reaction was predictable — "Mate, I've got 550 homes in construction. You've got one." But when he hung up the phone, he actually thought about it. And that's where things got interesting.

He narrowed down what a builder actually provides to three core things: a structured workflow, a curated trade and supply network, and expert oversight through site supervisors. Then he asked the question that changed everything: "What if we could put all of that into a platform and let the homeowner drive?"

Nine A-1 sheets of paper, 4,000 process boxes, and 20,000 arrows later, Danny created a flowchart of the entire home-building process. He showed it to his school friend Vince Marciano — a software engineer — and they started building during COVID lockdowns. Three years and $5 million in development later, BuildBuddy launched at the Sydney Home Show.

The results so far are compelling. Their very first customer, Greg Lurie, had been quoted $1.35 million by a traditional builder and was about to sell his block of land because he couldn't afford it. Using BuildBuddy, he poured his slab in May, moved in by February, and built his 48-square home for $860,000. That's a saving of nearly $500,000 — after tax.

But here's what I really love about BuildBuddy. It's not just about saving money. It's about what Danny calls "collaborative construction" — a completely new method of building that sits between the traditional builder model and the wild west of owner-building.

The platform's secret weapon is the Construction Buddy — a licensed building professional with at least 10 years of experience who reports directly to the homeowner, not to a building company. Danny drew the Uber analogy, and it's a good one: just as Uber created a new category of driver, BuildBuddy has created a new career path for experienced site supervisors who want to work directly with homeowners. The duty of care shifts entirely — your Construction Buddy works for you.

I also love how Danny has baked building industry best practice into the platform's DNA. The system won't let you proceed to the next stage until you've completed what needs to be done first. It won't let you book your bricklayer until your bricks are on site. And it forces you to select your shower taps before construction begins — because, as Danny patiently explained, that $300 mixer tap can cost you $10,000 if you choose it after the tiles and waterproofing are already done.

Then there's the transparent customer-driven review system for trades. Danny told me the story of "Barry the painter" — his company's painter who didn't show up because "surf was up," resulting in Hudson Homes copping a one-star review for work they didn't even do. Good tradies are worth their weight in gold, and BuildBuddy's review system is designed to reward them for it — not create a race to the bottom on price, but a race to the top on service.

On the AI front, BuildBuddy is using AI to develop an Early Price Guide that can upload a set of plans and generate a cost estimate within 5% accuracy. They're also working on "AI Barry" — an AI assistant that will chase up tradies who forget to submit their quotes. Because sometimes, the surf is just too good.

Danny's ambition is audacious: he believes that within five years, more homes will be built in Australia through BuildBuddy than through any single major builder. Even at a conservative one-in-twenty homeowners choosing the platform, that's 5% of the market — two and a half times bigger than Metricon, currently Australia's largest builder.

If Australia is going to solve its housing affordability and supply crisis, we need more construction innovation, not less. BuildBuddy is exactly the kind of brave, from-the-inside disruption that this industry needs. Danny, Vince, and the team — congratulations on your PropTech Award wins, and I cannot wait to see where this goes.
