About Jack
I'm Jack Chaffey, Director of Development at Stripes Group - a vertically integrated regional business operating across property development, engineering and civil construction, with a team of around 150 people.
My role covers site assessment, feasibility, consultant coordination, approvals, leasing and project strategy. I do that as part of a much broader team, because no commercial development is delivered by one person.
Through that role, I've led more than $45 million in commercial projects - completed and active developments - working alongside the wider Stripes team. So when I teach you what a DA actually costs, where a feasibility blows out, and what builders actually charge, it comes from live projects, not memory.
Development Navigator brings together the frameworks, tools and lessons I use across those projects - what has worked, what hasn't, and the mistakes that cost first-timers the most.
The goal isn't to promise easy money. It's to help you understand the process, assess opportunities clearly, and make your first commercial development a calculated move - not a gamble.
