Homes That Reflect the Way We Live on the North Shore 

Our homes are where life happens—in all its mess, movement, and meaning. On the North Shore, that might mean leafy backyards, bikes in the hallway, long dinners with friends, or a quiet retreat at the end of the day. At Hall & Hart, we design custom homes that speak to those moments—functional, beautiful, and deeply personal.

As locals ourselves, we understand the character of this place and the way families here want to live. Every block is different. Every street has its quirks. That’s why our approach is bespoke from the start.

We pair you with a senior designer who works with you closely—shaping a home around your block, your routines, and your aspirations. From design and styling to council and construction, the entire journey stays in-house, so nothing is lost in translation.

It’s a collaborative, clear process that gives you the benefits of a custom-designed North Shore home—without the complications or cost blowouts that often come with building one.

Considering a Custom Build on the North Shore? Start Here

Building a new home is one of the biggest decisions you’ll make—and it’s easy to get overwhelmed with options, opinions, and industry jargon. Whether you’ve spent years planning or are just starting to explore what’s possible, the path forward should feel clear and supported.

As custom home builders with deep experience across the North Shore and broader Sydney, we’ve helped many families turn uncertainty into confidence. Our custom build guide is designed to offer practical advice, highlight common pitfalls, and help you understand how knockdown rebuilds really work—before you commit.

If you’re thinking about a custom home, this guide is a good place to start.

What Impacts the Cost of a Knockdown Rebuild?

No two knockdown rebuilds are the same—which is why comparing one build’s costs to another rarely tells the full story. From demolition and site conditions to design choices and council overlays, every element plays a role in shaping the final figure.

At Hall & Hart, we work closely with you to break down costs early—layered with insight from real projects across the North Shore and beyond. We believe financial clarity should be part of the design process, not something that comes after.

Here are some of the most common factors that influence knockdown rebuild costs:

• Size of the existing home being demolished
• Site preparation, including clearing and excavation
• Location-based conditions—bushfire zones, heritage overlays, or coastal wind ratings
• Traffic management requirements (especially on narrow or busy streets)
• Asbestos removal or structural complexities in the original home
• Trees and neighbouring vegetation
• Hydraulics and stormwater planning
• Council-specific setbacks, slope or height restrictions
• Level of interior and finish selections
• Design or plan changes along the way

As North Shore home builders, we understand the nuance of building in suburbs like Northbridge, Roseville, and Lane Cove. From council expectations to block conditions, we factor it all into your planning—so you can move forward with confidence, not guesswork.

Sloping Blocks: A Challenge—And a Real Opportunity

Sloping land is often seen as a complication. But with the right design approach, it can open up possibilities that flat blocks can’t—sunken lounges, split-level living, soaring ceilings, and elevated views that make everyday life feel just a little more special.

Designing a custom home on a sloping block in areas like Northbridge or across the North Shore takes more than standard solutions. It takes considered planning—from understanding the presence of rock and minimising excavation, to shaping your design to suit the fall of the land and unlock real cost efficiencies. In some cases, a carefully planned design can even allow you to bypass Willoughby Council requirements and pursue a faster CDC pathway.

At Hall & Hart, we specialise in building on complex sites—and helping you make the most of them. With early site analysis, tailored design, and in-house planning and pricing, we help you turn what’s often seen as a challenge into a real advantage.
