Custom Home Builder Newcastle | Thoughtfully Crafted Homes

Design-led homes built with integrity, craftsmanship, and a deep understanding of how Novocastrians live.

Custom Homes that Reflect Newcastle Living

At Alchemy Built, we create custom homes defined by design integrity, exceptional craftsmanship, and a deep understanding of how you live. Every home is considered from the ground up, tailored to your site, surroundings, and the people who call it home.

Whether it’s a new architectural build in Boolaroo or a knockdown rebuild near Merewether beach, our process is grounded in collaboration, transparency, and care. We bring together the right people – clients, architects, and designers – to create homes that feel timeless, functional, and deeply personal.

Building Alongside You and Your Architect

Exceptional homes begin with strong foundations, not just in structure, but in partnership. We work seamlessly alongside your architect or designer, or can connect you with trusted local professionals who share our commitment to design excellence.

Our team considers every detail – proportion, materiality, light, sustainability, and flow – ensuring each element works in harmony. Every decision is made with intention, resulting in a home that feels cohesive, enduring, and beautifully resolved. From inner-city residences to thoughtfully designed coastal retreats in Redhead, our projects are united by craftsmanship, quality, and restraint.

The Alchemy Approach

Building a home is one of the most important decisions you’ll make – and as a custom home builder in Newcastle, we believe the process should feel personal and seamless from start to finish.
We guide you through the journey with clarity and warmth. We keep communication open, expectations honest, and timelines clear. But above all, we make sure your vision is honoured – every decision, every finish, every detail is chosen with intention and respect for the outcome.

We care about how the build feels: the trust you feel in us, the excitement of seeing the design take shape, the confidence in the craftsmanship. Because when the process is as thoughtful as the home itself, you end up with something truly special – a home built for the way you live and built to endure.

From Our Clients

We couldn’t be happier with our experience working with Jeff and Alchemy Built! From day one, Jeff’s communication was amazing- he kept us in the loop every step of the way and always took the time to explain things clearly. The craftsmanship is absolutely beautiful. You can tell Jeff really cares about the work he does- every detail in our home was done with so much care and pride. He constantly went above and beyond to make sure everything turned out even better than we imagined. We honestly love our house, and it’s all thanks to Jeff and his team. If you’re looking for someone who’s not only talented but also genuinely great to work with, we can’t recommend Alchemy Built enough!

I have engaged Alchemy Built a number of times at my property- a Victorian weatherboard c 1890 that has required updating in a number of areas. Jeff is focused and very pleasant to deal with. He has the experience required to plan the workflow and coordinate the trades in a timely manner within the deadline required. Jeff also has the ability to provide guidance and expertise in relation to the projects undertaken. Alchemy Built is my builder of choice - and I look forward to working again with Jeff on future projects.

Jeff is an outstanding builder who was an absolute pleasure to work with. His work ethic and the quality of his finishes are exceptional. He made the renovation of our home an enjoyable experience. Could not recommend him any higher.
