OUR PROCESS
Custom Home Builder
The Amberstone Difference
Three things you can count on.
Clear communication
Kept informed at every stage, from slab to keys.
Built around you
Any style, any material — shaped to how you live, refined as we go.
Built to last
Considered design that builds in efficiency and longevity.
Our Commitment
Fixed price. Fixed time. Open books.
Our price is fixed
As a builder, we bear the risks in the later stages of construction. You will never pay a cent beyond what is written in the contract.
Our time is fixed
Every site has a dedicated manager and a committed completion date — with compensation for any delay, your build stays on budget and on time.
Our quality is transparent
Log in to our management system any time. A progress report for every stage arrives weekly, keeping each detail open to your inspection.
From first sketch to the day you collect the keys
We lead you step by step through the entire journey — listening closely and solving creatively at every turn.

How We Build
Solid by standard. Finished by hand.
Double brick and suspended concrete on every home — then joinery and finishes brought to the last millimetre.

Common questions.
Everything needed to hand you the keys: the structure — double brick and suspended concrete as standard — all internal finishes and joinery, external works and landscaping as documented, plus the three disciplines we include with every home: a quantity surveyor’s cost plan, panoramic visualisation and in-house interior design. Anything excluded is listed by name in the contract, so there are no surprises later.
Most of our homes take between 10 and 16 months on site, depending on scale, site conditions and council. Your contract carries a committed completion date — and if we run late, we compensate you for the delay.
Yes. Every home is covered by the statutory warranties under the NSW Home Building Act — six years for major defects and two years for other work — and the contract is insured under the Home Building Compensation Fund. Beyond that, the same people who built your home still answer the phone.
A fixed-price residential building contract. The price is built on a quantity surveyor’s cost plan and detailed documentation before you sign, so it does not move unless you change the scope. The same contract carries a fixed completion date.
Both work. We design in-house and have long relationships with architects such as Tesser Arch, and many clients arrive with an architect already appointed — we are comfortable building to another practice’s documentation. Interior design is included with every home either way.
Four stages. Design development and approval: consultants appointed, budget set, development application managed. Detailed design: tender-ready documentation and the quantity surveyor’s cost schedule. Tender and construction: a fixed-price contract, a dedicated site manager and a weekly progress report. Completion: council sign-off, handover and the keys. You can follow every stage through our online project portal.
