AMBERSTONE GROUP
Sydney Custom Home Builder
BUILD YOURLuxuryHOME
Amberstone Group is a Sydney custom home builder, crafting bespoke luxury residences of enduring quality across greater Sydney.
From knock-down rebuilds to luxury duplex developments, every project is designed, engineered and delivered by our own team — one contract, one dedicated site manager, and one uncompromising standard of craftsmanship from slab to keys. Where we truly excel is design. Our architects and interior designers take the time to understand how each family lives, then translate that insight into a bespoke residence shaped around their lifestyle, taste and long-term aspirations — a home refined down to the very last detail. This is high-end custom building at its most considered.
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

FAQs
What's included in the price of a custom home?
The price typically includes all construction work, interior finishes, and exterior landscaping. Some builders may also include design and architectural services.
How long does it take to build a custom home?
The timeframe can vary widely, depending on the complexity of the design and the size of the home, but on average it takes about 10-16 months from start to finish.
Do you offer a warranty?
Yes, we offer a warranty that typically covers workmanship and materials for a certain period of time after the home is completed.
What type of contract do you use?

Do you have a design team, or should I hire an architect?
We have an in-house design team that can help you design your dream home. However, if you prefer to work with an external architect, we’re happy to collaborate.
