Build your dream home with a custom new home build

At Ajax Building Contractors, we specialise in new home builds designed specifically to suit your lifestyle, needs, and future aspirations.
If you have already worked with an architect or have consented plans, we can work from those to build your new home. Alternatively, we can design properties up to two stories, and can help you design your home before completing the build.
Throughout the construction process, we manage every detail to deliver a hassle-free experience, including site preparation, foundations, framing, roofing and finishing touches. We always ensure each new build home meets building codes and exceeds your expectations.

Create extra space with seamless home extensions

If your home is feeling cramped or no longer meets your needs, a home extension is often more affordable than moving house and creates less disruption, especially if you love the location you are in.
Ajax Building Contractors are experts in designing and constructing extensions that blend seamlessly with your existing property.
Common home extensions include:
  • Rear extensions: Expand your home into your garden for additional living or entertaining space.
  • Side extensions: Use available land beside your home to create more room.
  • Second-storey additions: Build upwards to accommodate extra bedrooms, bathrooms, or office space.
  • Garage conversions: Redesign unused space to provide extra living space, a home office or playroom or a gym.
Our team will guide you through key considerations such as council permits, as well as ensuring the existing structure can support the new extension and that the new building will not adversely affect heating, cooling or natural light.

  • Bathroom renovations: Upgrade your bathroom with sleek fixtures, elegant finishes, and practical layouts.
