Design · Build · Maintain
From first idea to final key — one team, one budget, no gaps.
We manage your renovation or extension end to end — feasibility, your independent designer and consultants, buildability, real-quote pricing and the turnkey build. Already have approved plans? We’ll price them line by line and build exactly what’s drawn.
Why projects blow out
Most budgets are broken before the build even starts.
We manage design and cost together from day one — so what gets drawn is what you can afford to build, and one licensed builder is accountable for all of it.
Plans drawn without a price
The design comes back at double the budget — and you’ve already paid for the drawings.
Quotes that guess
Vague allowances look cheap on paper, then turn into variations halfway through.
Nobody owns the gaps
Designer, engineer and builder each point at the other when something doesn’t fit.
Your options
Four ways to work with us.
Every project starts in one of these four places. Every fee is published — before we ever meet.

What our clients and trade partners say
“They know their trade inside out, plan the work properly and keep everyone involved informed, which makes a real difference on the more complex jobs… They’re honest with their clients, realistic with timeframes and the standard of finish speaks for itself.”
“Professionalism shone through from our first meeting. He understood what our aims were and talked through options… kept us informed on timing throughout and completed works ahead of anticipated timings.”
“A very quick turnaround of just one week to update a unit we’d purchased… Everything was finished to a very high standard… very considerate when working alongside other trades onsite. He made the entire renovation process smooth and stress-free.”
“Professional, expert experience combined with vision and resourcefulness make Jamie my go-to builder for those important projects. From newly designed walk-in robes for my own home to rebuilding decks and stairs for my clients.”
“Well done team, great finish. Very happy with the result and the whole process. Easy to communicate… super honest. Will definitely use them next time.”
“Worked harder than any other tradie I have ever had. Offered a quality finish too. He also moved his schedule around to complete additional work for us that came up mid job.”

Good questions, honest answers
What if I decide not to go ahead?
Stop after any stage before the build contract. You keep your Feasibility Estimate and quote, and there are no exit fees.
Which fees come off my build price?
If you sign within 60 days: the Feasibility Estimate, the detailed quote fee and small works site visits. Management fees don’t, because they pay for a service.
Do you design the project?
No — we’re builders. An independent building designer or architect prepares your drawings and sets their own fees. We recommend one, brief them on your budget and manage them for you.
Can I use my own architect or designer?
Yes. If your drawings and engineering are done, choose Build Only: we go straight to a detailed quote, and the fee comes off your build price.
Why might my price change between stages?
Because the detail changes. Selections, finishes and design decisions all move the price. Once you sign, it’s fixed except for approved variations and listed allowances.
Is my small job too small for you?
No. Repairs and one-off jobs under $20k with a clear scope are Small Works: a free quote from photos, or $500 + GST if we need to measure on site.
Are you licensed and insured?
Yes. QBCC Licence 15559311, $20 million public liability, Master Builders Queensland member, and eligible work is covered by the Queensland Home Warranty Scheme.
