New Homes, Duplexes, Renovations & Additions in Sydney

For more than 20 years, Domus Homes has been designing and building exceptional custom homes across Sydney’s North Shore.
From new homes and knockdown rebuilds to duplexes and dual occupancies, we manage every detail from the first concept through to final handover. Design, documentation, interiors and construction are all brought together under one experienced team, giving you one point of accountability and a simpler way to build.
With experience across Killara, Wahroonga, Turramurra and Castle Cove, our custom home designers and builders in the North Shore understand these local considerations and how to manage them while delivering a home that works beautifully for its site and the people who live there.
As one of Sydney’s most experienced construction project management companies, we oversee every stage of your North Shore project, from early design conversations through council approvals to the final coat of paint. Design, approvals, trades, materials and budget all come together under one plan, with a single team keeping everything moving.
For a North Shore project, that means council considerations like tree preservation and heritage conservation are built into the plan from the outset. You’ll always know where things stand, and who to speak to about it.

Our custom home designers take your idea and turn it into a finished home.
Starting with a vacant block or a cleared site, our building designer in the North Shore gets started with plans, then carries that design straight through into construction. Your home is developed to suit its site, its street, and the way you want to live.
When the location is right, but the existing home no longer fits, a knockdown rebuild lets you begin again in the suburb you already love. We manage the demolition, any site works, and the new build.
Duplex projects, particularly across Killara and Wahroonga, call for a careful balance of design quality and council requirements around separation and parking. We create duplexes that meet both, while still feeling like two beautifully finished homes.
For investors and developers, a dual occupancy is about achieving the right yield from a site without compromising on quality. We manage feasibility, DA lodgement and construction as one project, with a single point of contact throughout.
Building on the North Shore comes with its own considerations, and having worked across these four suburbs, we understand what each one calls for. As a custom home designer in the North Shore, we bring this same local understanding to every site we work on.
Tree-lined streets and generous, established blocks make Killara a natural fit for knockdown rebuilds, with many properties sitting within a Ku-ring-gai heritage conservation area that shapes decisions around roofline and street setback.
If you're weighing up a renovation against a full rebuild, our Killara renovation project management team can talk you through both.
Wahroonga's larger blocks and leafy outlook suit families building a long-term home rather than an investment. Deep setbacks and established tree canopy are part of the character we design around here, alongside bushfire considerations in some pockets.
A mix of Federation-era and mid-century homes sit across Turramurra's sloping, sometimes ridge-line blocks, where the view is often part of the appeal. Heritage listings vary from street to street, so we check each property's specific status early in the design process.
Set apart in the Willoughby local government area, Castle Cove's steep blocks run down toward Garigal National Park, calling for careful attention to retaining walls, drainage and bushfire ratings from the earliest design stages. Our renovation project management in Castle Cove is built around exactly these conditions.


A significant investment deserves careful oversight. As a construction project management team for the North Shore, we coordinate design, documentation, interiors, consultants and construction under one roof, so you have one team accountable for the whole project.

Building a custom home on the North Shore is about more than construction. It’s about understanding a site and a suburb well enough to get it right the first time.

Every project is different, so cost depends on the size of the home, the scope of work and the level of finish you choose. Our custom home builders will establish a clear budget with you before construction begins, so you always know where your money is going.
Most knockdown rebuilds require development application approval through Ku-ring-gai Council, particularly where a property sits within a heritage conservation area or has protected trees on site. Our North Shore custom home builders manage this process for you, including the required documentation and liaison with council.
A duplex is typically two attached homes held on a single or separate title, while a dual occupancy is often designed with future subdivision into separate titles in mind. This changes both the design approach and the council approval pathway, and we can advise on which suits your goals.
Timeframes vary depending on council processing and site conditions, but most knockdown rebuilds across Killara, Wahroonga and Turramurra take around 12 to 18 months from approval through to handover. We’ll give you a realistic timeline once we understand your site and brief.
You’ll have a dedicated point of contact, backed by our wider team of designers, project managers and builders.
Our core focus is Killara, Wahroonga, Turramurra and Castle Cove, and we also take on select projects in nearby suburbs including Lindfield, Roseville, Pymble and St Ives. Get in touch, and we can let you know if your site is a fit.
