New Homes, Duplexes, Renovations & Additions in Sydney

A great custom home should feel right from the moment you walk through the door and continue to stand the test of time.
For more than 20 years, Domus Homes has been helping Sydney homeowners achieve high-end custom homes and bring their ideas to life. From new homes and duplexes to thoughtfully designed renovations, we work with clients across the North Shore, Inner West and Eastern Suburbs, taking care of every stage from the first concept through to the final handover.
Because design, documentation, interiors and construction are all managed by one experienced team, the whole process feels simpler. You have one team to talk to, one clear point of accountability and no need to coordinate architects, certifiers and trades yourself.
As custom design home builders in Sydney, we manage every stage of your project ourselves, rather than handing you between separate consultants and contractors along the way. Here's what that looks like in practice.
Every project begins with a 3D concept design, shaped around your block, your brief and the way you want to live. This is where the big decisions get made, well before any money is spent on construction.
From there, we prepare your Development Application (DA) or Complying Development Certificate (CDC), bringing together the consultants and specialists needed to get your design approval-ready.
Your DA or CDC is then submitted to the council or your building certifier. We follow the application through from there, resolving any queries as they arise so momentum isn't lost.
Once approved, we prepare detailed construction documentation covering custom design, landscape architecture and engineering, so your builders have what they need to build to plan.
We manage the tender process on your behalf, drawing on a trusted network of builders and trades to secure the right team at a competitive price.
Through construction, we provide contract administration and ongoing design input, staying closely involved until your home is delivered to the standard you signed up for. For styling and finishes along the way, our interior design consultation in Sydney can run alongside this final stage.
Whether you’ve bought a block or already own the land, we design new homes around your site, your budget and your family’s stage of life, not a display-home template.
When renovating no longer makes sense, a knockdown rebuild lets you start again on land you already know and love, this time designed properly for it.
For families and investors alike, we design duplexes that balance two genuinely liveable, well-proportioned homes on a single title.
Dual occupancy projects call for careful planning around access, privacy and council requirements. We manage that complexity so the finished result works well for everyone living there.
Affluent homeowners, established families and property investors turn to Domus Homes as their high-end custom home builders in Sydney for clear reasons.


As local custom home builders in Sydney, we know the North Shore’s blocks nearly as well as we know its councils. From Castle Cove’s sloping sites to the established, leafy streets of Pymble, Roseville and Killara, our custom home designers on the North Shore understand the heritage overlays and setback rules that shape what you can build.
That local knowledge, paired with our wider experience across the Northern Beaches, Inner West and Eastern Suburbs, means fewer surprises once your project reaches council.
Planning a new home, duplex, knockdown rebuild or dual occupancy?
As custom home builders in Sydney, we’d welcome the chance to walk through what you have in mind and how our six-stage process would apply to your site.
Get in touch with Domus Homes for an obligation-free conversation, or call us on (02) 9144 6247. For projects needing broader oversight across multiple trades, our construction project management company in Sydney can take that off your plate.

Cost depends on size, scope and finish level. We set a clear budget before construction begins and keep you updated throughout.
It depends on the project. A duplex or dual occupancy runs to a different timeline than a straightforward new home, and we’ll give you a realistic estimate once we understand your brief.
Most new homes, duplexes and dual occupancies need DA or CDC approval. We manage this for you, including documentation and council liaison, as part of Stage 2 and Stage 3.
Yes. You’ll have a dedicated point of contact backed by our designers, project managers and trusted builders, rather than coordinating everyone yourself.
We work across new homes, knockdown rebuilds, duplexes, dual occupancies, semis, terraces and apartments, tailoring the six-stage process to each project’s scale.
We regularly work across the North Shore, including Castle Cove, Pymble, Roseville and Killara, plus the Northern Beaches, Inner West and Eastern Suburbs, including Woollahra, Randwick, Mosman and Lane Cove.
