Spacious double-storey house designs in Sydney

From the leafy laneways of the Inner West to the breezy ridgelines of the Northern Beaches, Sydney’s landscapes are as diverse as its people. And with so many ways to live, your home should reflect your unique needs, preferences, and pace of life. 

In a city where space is precious, building up — not out — can offer the breathing room you need without sacrificing location. That’s why our double-storey home designs in Sydney are created to give you more flexibility, more comfort, and more joy across every level.

Whether you’re dreaming of a layout that keeps sleeping quarters upstairs and the hustle of daily life below, or you’re working with a narrow block near the CBD, we’ll help you make the most of every square metre — with thoughtful design that works now and for years to come.

Smart design, beautiful flow, local expertise

From smart zoning and private retreats to light-filled open-plan living and elevated views, our two-storey home designs in Sydney are crafted for modern NSW living. Whether you’re after something compact for an urban block or a more expansive layout for a growing family, we’ll tailor the design to your needs — without compromising on comfort, style or liveability.

With more than 60,000 homes built across Australia and over 40 years of experience behind us, our Sydney team knows the climate, the council requirements, and the details that make a house truly feel like home. And because every journey starts with a conversation, your local New Home Consultant will be there to guide you — from personalising the floorplan to selecting your finishes. Contact us today to learn more.

Explore our range of double-storey house plans for Sydney, and when you’re ready, we’ll help you build something that’s perfectly you — crafted with care, experience, and joy every step of the way.

FAQs

  • What are the benefits of choosing a double-storey home design in Sydney?

    A double-storey home gives you the ability to maximise your block size — especially in popular Sydney suburbs where land can be limited or costly. With two levels, you gain extra living space, better separation between living and sleeping zones, and the opportunity to take in views and breezes from above. It’s also a smart solution for compact or sloping blocks commonly found throughout Sydney.

  • Are your designs available across Sydney?

    Yes. As trusted double-storey home builders in Sydney, we build homes across the region — from the North West and the South to the Northern Beaches, the West, and beyond. Our local teams understand the council overlays, site conditions, and regulations that shape how and where you can build. We’ll work with you to tailor a double-storey design that suits your block, lifestyle, and long-term goals.

  • Are your double-storey homes suitable for narrow or compact blocks?

    Absolutely. We offer a wide range of double-storey house plans in Sydney that are purposefully designed for narrow and small lots, particularly in urban and infill locations. These designs prioritise smart layouts, natural light, and flexible living zones — all within a smaller footprint.

  • Can I customise the layout of my double-storey home?

    Yes — every double-storey home design can be tailored to suit your lifestyle, block, and aesthetic. Whether you want to reconfigure rooms, add extra bedrooms, or personalise your façade and finishes, your New Home Consultant will guide you through it. We’ll also support you through your colour selections — from fittings and fixtures to materials and paint choices — so your new home reflects your vision, inside and out.

  • Do you offer designs with upstairs living or master suites?

    Yes. Many of our double-storey house designs in Sydney feature master suites on the upper level, along with flexible layouts that include upstairs living spaces, balconies, and teen or guest retreats. These are ideal for families looking for privacy, separation, or future flexibility in the way they live.

  • Can I visit a display home to see double-storey designs in person?

    Yes — we have a selection of double-storey display homes in Sydney and surrounds that showcase a range of layouts, styles, and inclusions. Visiting a display home allows you to see how the space flows, experience the finishes up close, and picture how your own home could take shape. You can find your nearest location via our Display Homes page or by speaking with your local G.J. Gardner team.

    Does G.J. Gardner offer knockdown rebuilds in Sydney?

    Yes — we offer a full knockdown rebuild service in Sydney. If you love your location but your home no longer suits your lifestyle, we can help you start fresh on the same block. From demolition to design and build, our local teams will guide you through the entire process with customisable floorplans, fixed-price contracts, and expert advice tailored to your site.

  • How much does it cost to build a double-storey house in Sydney?

    The cost of building a double-storey house in Sydney will depend on your chosen design, your block’s features, and how much you personalise your inclusions. To get a clear, tailored quote, your first step is to speak with one of our New Home Consultants. They’ll help you adjust your floorplan, understand your options, and provide a detailed estimate that reflects your goals and lifestyle — with no hidden surprises.
