Knockdown Rebuild
Absolutely. We regularly work with customers who choose to knock down an existing home and rebuild on their current site.
We manage the process holistically - from early feasibility and design through demolition, approvals and construction - ensuring the new home better accommodates the land, orientation, and modern living needs.

Yes. In fact, this is one of our specialties.
Sloping sites, narrow frontages, complex access, reactive soil conditions or challenging overlays require experience and considered planning. Rather than avoiding complexity, we assess it early and manage it methodically.
Our team conducts thorough site analysis upfront – including contours, soil classification, access constraints and service connections – so risks are identified before construction begins.
Difficult blocks often produce the most interesting homes. With the right planning and structural expertise, they can deliver exceptional outcomes – and we're experienced in navigating that complexity.
We build across Sydney and surrounding regions, focusing on locations where design quality, craftsmanship, and thoughtful planning add genuine value.
You can check our Build Map to see if we’re currently building in your area or call our team to check your particular address. We constantly reassess our build zones, so if you’re unsure whether your site falls within our build area, we’re happy to discuss your location and advise early.
No. You can speak with us at any stage - whether you already own land, are considering a purchase, or are still exploring options.
In fact, engaging early can be valuable. We can help assess site potential, constraints, and opportunities before you commit, ensuring your future home is designed with clarity and confidence from the outset.
Yes. We coordinate the design documentation, approvals process, and any required consultants as part of the journey.
Our role is to simplify what can otherwise feel complex, keeping you informed while managing the technical details behind the scenes.
The investment required to build a home with ZAC varies depending on your site conditions, design approach, level of customisation and the finishes you choose. Rather than quoting a headline figure, we focus on helping you understand what drives cost – and how those decisions connect back to how you want to live.
From the outset, we provide realistic guidance based on comparable projects, detailed site assessments, and transparent allowances. We break down where your budget is being allocated – structure, site works, selections, and specification – so you can see exactly how your home is coming together financially.
Importantly, we don’t just price a design. We work with you to shape a home that aligns with your lifestyle priorities and your investment comfort zone. That may mean refining scope, adjusting levels of finish, or reconfiguring elements to achieve better value without compromising the intent.
Our role is to remove uncertainty. By combining early clarity, structured cost planning and ongoing communication, we help you move forward with confidence – knowing your home has been thoughtfully designed and realistically budgeted from day one.
Yes. Pools can be incorporated into the design and construction process from the outset. In fact, planning for a pool early allows us to co-ordinate structural requirements, services, drainage and outdoor living integration more effectively.
We can manage the pool build directly or co-ordinate with a preferred pool contractor to ensure timelines, compliance and finishes are aligned.
When integrated properly, a pool becomes part of the overall design – not an afterthought.
Yes. Our bespoke custom homes are designed from the ground up, around you.
That means layouts, materials, finishes, and spatial relationships are all tailored to your lifestyle, site conditions, and long-term plans. We don’t start with a template - we start with how you want to live. We can also work with existing Architects' plans or modify or adapt a plan to suit.
Homes by ZAC is design-led, detail-focused, and life-first in approach.
We invest time upfront to understand how you live, how the site behaves, and how the home should feel - now and into the future. The result is a home that is considered, enduring, and genuinely personal.
What also sets ZAC apart is that the business is still owner-led and owner-involved. Our directors remain actively engaged in the company day to day – across design, documentation and construction oversight. That means decisions are not filtered through layers of management, and accountability is direct.
With more than 30 years of experience, we bring depth of knowledge to every stage of the process. We anticipate complexity, manage detail behind the scenes, and provide clear guidance when decisions matter.
You’re not working with a production system. You’re working with experienced professionals who are personally invested in the quality, execution and outcome of every home we build.
