A luxury duplex should feel like two genuinely private, high-end homes, not one large house split in half. At Clover Homes, our luxury duplex designs start with what you’ll notice every day: how quiet the shared wall is, how each home is laid out, and the quality of what you touch.
Talk to us about your block and your brief. We’ll put together a beautiful, modern duplex house design built around what actually makes a duplex feel luxury.
Two households sharing a wall creates a problem a standalone luxury home never has to solve. Getting it right means:
The National Construction Code requires a separating wall between attached homes to reach Rw + Ctr 50, with discontinuous construction where a bathroom, laundry or kitchen backs onto a living or bedroom space next door (NCC Housing Provisions Part 10.7). We treat that as the starting point, not the goal.
Bedrooms and living areas are planned so they don't mirror straight into the home next door, and wet areas are kept off the shared wall where possible.
Genuine material quality where it gets daily use: benchtops, tapware, flooring and joinery. Modern duplex house interior design is about how finishes perform in ten years, not how they look on handover day.
Considered exterior design gives each dwelling its own facade, entry and identity, so it reads as two homes, not one split in half. See our approach to duplex facades on our double storey duplex page.

No. It's common to use different finishes in each dwelling, especially if one side will be rented or sold, or the two households want different styling.
The NCC minimum for the wall between attached homes is Rw + Ctr 50. That's a compliance bar, not a luxury standard.
Ask your builder what rating their party wall system achieves, and whether bathrooms, laundries and kitchens are kept off the shared wall. The ABCB sound transmission handbook explains how these ratings work.
Yes, as long as the design responds to the block rather than forcing a standard layout onto it. Irregular sites often benefit most from custom luxury duplex designs.

Not with us. Our in-house design team designs your luxury duplex and works directly with our builders, so you don't need to hire a separate duplex architect.

Not inherently. Cost is driven more by finishes, site conditions and scale than by whether the design is custom or off the shelf.

As involved as you want to be. We work through selections together, so the finishes reflect your taste.
