The worry is committing to a build without knowing what you’re really getting.
Your current home might feel cramped and dated. Your vacant block might be waiting for the right design. Or your family might need two homes with room to live independently.
You’re ready to explore the possibilities. But comparing builders can leave you with more questions.
Does the price include the site work? Are the allowances realistic for the finishes you want? Will the inside feel as considered as the façade?
Then there’s the worry about what happens after signing. Chasing updates. Discovering extra costs. Explaining the same decisions to different people.
This is a home you’ll live with for years. You want to feel confident about the builder and the decisions before construction begins.
A clearer way forward
Get the important details clear before the build begins.
JB Prime Homes starts with your land, your family and your budget. We review the site, bring the design and construction budget together, and clarify inclusions, allowances and major selections before construction.
We then coordinate the project through approvals, construction and handover, with progress updates every two weeks and support after completion.
You can make decisions with a clearer understanding of what’s being built, what’s included and who is managing the work.
02
A premium custom home on vacant land
Build around your block and your priorities, from entertaining spaces and high-end finishes to basements and designs for sloping or difficult sites.
03
A custom premium duplex
Create two homes on the same land for multiple generations with their own privacy, or pursue investment goals such as two rental incomes, capital growth and increased equity. Site suitability must be assessed, and financial outcomes are not guaranteed.

Customer reviews
What our clients say.
Feedback from custom home, knockdown rebuild and duplex projects across Sydney’s north.
“We’d lived in Chatswood for twenty years and didn’t want to leave. JB Prime Homes managed the knockdown and rebuild from start to finish, and the fortnightly updates meant we always knew where things stood.”
“From the first consultation through to handover, everything was explained clearly. The inclusions and allowances were spelled out before construction, so there were no surprises.”
“We built a duplex so our parents could live close by with a front door of their own. JB Prime Homes coordinated the planning and kept the whole process calm and structured.”
“Demolishing and rebuilding in the suburb we love felt daunting, but the site review and design discussion early on made the decisions much easier. We couldn’t be happier with the result.”
“Our block slopes, and other builders were vague about what that meant. JB Prime Homes explained the site requirements and the construction approach clearly before we committed.”
“JB Prime Homes assessed our land properly before we committed to the duplex. The fortnightly progress updates during construction were exactly what we needed.”

Built for living
A home that feels right on an ordinary day.
There’s room for everyone at dinner. A quiet space when someone needs privacy. Living areas that open onto the outdoor space you’ve wanted for years.
For a family duplex, it might mean parents close by with a front door of their own. For a home on vacant land, it’s finally seeing the place you imagined become somewhere you belong.
The pleasure is in living there, long after the first time you show friends around.

FAQ
Questions before you build.
How much will my custom home or duplex cost?
The cost depends on the land, design, size, site requirements and inclusions. We start with your budget expectations, then work through the design and scope to establish realistic construction costs for your project.
Can you build on my vacant block?
Yes. Premium custom homes on vacant land are part of our work. We review the block’s conditions, access and planning requirements as part of assessing the project.
Can I knock down my current house and rebuild?
Yes. We work with owners who want a new custom home in the suburb they already love. The initial review helps identify the site requirements and planning considerations for your rebuild.
Can you build a duplex for family living or rental use?
Yes. We can discuss a duplex designed for independent family living or rental use. Whether the proposed build suits your land needs to be assessed. Rental income, capital growth and increased equity are potential goals, not guaranteed outcomes.
Do I need completed plans before contacting you?
No. You can come to us with an idea, concept drawings, detailed plans or approved plans. We’ll discuss your current stage and the work needed to move the project forward.
Can you handle a sloping block or basement?
We have the capability to handle basements, sloping land and complicated builds. Your site review helps establish what the proposed design involves and how those requirements affect the scope and budget.
How long will the build take, and how soon can we start?
Timing depends on your design stage, required approvals, site complexity, scope and scheduling. We discuss your intended timeframe during the consultation and work through the project schedule as planning develops.
How do you handle extra costs and variations?
We clarify inclusions, allowances and major selections before construction. Our commitments are no hidden variations and no builder’s margin on variations. Changes to the work can still change its cost.
How will I know what’s happening during construction?
We have a process to update you on building progress every two weeks. These updates keep you informed as the build moves through its stages.
What if something needs attention after handover?
We complete handover inspections, document outstanding items and provide post-completion support. We provide a two-year defect rectification warranty and six-year structural warranty, and pass on fixture and appliance warranties.
