Extensions & Renovations
Extensions and renovations delivered with the same fixed-price certainty, honest communication, and Spruce Standard finish we bring to every new TCB Build home.
The Problem
Ask anyone who has renovated and you'll hear the same stories. A quote that doubled once the walls came down. A builder who vanished for weeks between trades. A six-week bathroom that dragged into six months while the family lived out of boxes.
Renovating your home shouldn't mean surrendering control of it. The uncertainty, the open-ended costs, and the silence between updates are exactly the problems we set out to solve.
Our Approach
Every extension or renovation starts with the Straight-Talk Discovery: an honest conversation about what you want to change, what your home can support, and what you can spend. If something in your brief isn't achievable within your budget, you'll hear it from us before anything is signed - not after demolition day.
From there we scope the work in detail, investigate the existing structure properly, and hand you a fixed-price contract you can hold us to. No provisional sums doing the heavy lifting. No surprises hiding in the fine print.
The TCB Build Difference
Most builders quote on plans they didn't draw, so when budgets blow out, you're stuck between them and the architect. We're different. We manage design and build together with precision scheduling, keeping plans on budget and backing it with a 12-month guarantee.*
01
We sit down face-to-face to discuss your vision, your non-negotiables, and your hard budget ceiling. We'll introduce you to our Design Portal to find the perfect starting point.
02
We take your chosen layout from the portal and tweak it to match your exact block and family needs. You get a fixed-price contract with absolute certainty - no allowances, no estimates, just the real number.
03
You'll see visible progress every single week. Our organised, tidy sites ensure maximum efficiency and Million Dollar Standard quality, even when you aren't watching.
04
No limbo, no dragging on. We hand over the keys to your pristine new home within 12 months of going ahead, making handover a true celebration.
The TCB Build Difference
A lot of builders quote on plans they didn't draw, leaving you caught in the middle of arguments between architects and builders when the budget eventually blows out. We do things differently. We oversee the entire design process, working hand-in-glove with our trusted design partners. Once on site, there isn't just one project manager; our entire team drives the momentum forward. By managing the whole job with precision scheduling, we ensure the plans match your budget, and we can confidently back our 12-month guarantee.*

Our Work
Testimonials
We were terrified of building after hearing horror stories from friends about budgets doubling and timelines blowing out. TCB Build was straight up with us from day one. The site was always spotless, the communication was clear, and they handed us the keys exactly when they said they would.
The Henderson Family, Wynyard
What sold us on TCB was that the fixed price actually was fixed. No surprise invoices, no "oh that wasn't included" conversations halfway through. Every variation was costed and signed off before a tool was lifted. We moved in on budget and we still talk to the team like friends.
Mark & Sarah, Burnie
We had a hundred questions as first-home builders and every one of them got answered within the day. The portal showed us exactly where we were up to, which trades were on site, and what was coming next. It felt less like a building project and more like a partnership.
The Patel Family, Devonport
You can tell the difference between a house that's been thrown up and one that's been built properly. Doors close with a thunk, the joinery is dead level, and the finishes still look brand new two winters in. The Spruce Standard is the real deal.
Jessie & Tom, Latrobe
From the first design meeting to handover the whole crew treated our home like it was their own. They protected the floors, cleaned up every Friday, and walked us through every detail at handover. We'd build with TCB again tomorrow and we tell anyone who'll listen.
The O'Brien Family, Smithton
Timeline Certainty
Living through a renovation is only bearable when you know exactly when it ends. Your timeline is agreed up front and written into your contract, and we plan every trade months in advance so the job never sits idle waiting for the next crew.
We deliberately limit how many projects we take on each year. We never overcommit, and we never stack jobs - which is how your extension keeps moving while other builders' sites sit quiet.
Why Clients Choose TCB
Renovation clients choose TCB Build because we act like partners, not contractors. We protect the parts of your home you're keeping, keep the site clean and liveable, and work around your family's routine wherever the build allows.
Every Friday, no matter what stage the work is at, you receive a photo update from site. If something changes, you hear it from us first - straight, clear, and without spin.
Extension & Renovation Pricing
Every home and every brief is different, so extension and renovation pricing is quoted on application after the Straight-Talk Discovery and a proper inspection of your existing home. That inspection is what lets us fix the price with confidence.
All pricing is locked in before you sign - no open-ended estimates, no allowances designed to blow out later. Start a conversation and we'll walk you through the complete process from first chat to fixed-price contract.
The Spruce Standard
The Spruce Standard is our benchmark for scheduling, workmanship, and site care - and it applies to renovations just as it does to new builds. Trades are booked months ahead, every stage is sequenced to eliminate lag days, and the finish is checked against the same standard we hand over on a brand-new home.
The result is an extension or renovation that blends seamlessly with your existing home - matched finishes, clean junctions, and a build process that respects the fact you're still living there.
