How Much to Build a Custom Design Home in Sydney?

How Much Does It Cost to Build a Custom Home?

Tue 7th July

There are a variety of things to know when building a custom home; particularly surrounding the costs involved in this process. There are so many variables that go into the design of a new bespoke home, that the answer will depend on your custom requirements and what your dream home entails.

The good news is that we can give you a “ballpark” cost early in the process, to give you an idea of what’s possible and to determine whether it’s the right path for you. One of our consultants can meet you for a site inspection, and based on our extensive experience we can provide an estimate once we’ve had a discussion about your desired home.


The good news is that with over 30 years’ experience, we can give you a very accurate assessment of what the costs would be to build your home. We’ll also let you know if there are any special factors you might need to take into consideration when building your new home.

We believe that standing on the site is the best way to really get an idea of costs.

Whilst you can give someone a general guide, we know that you cannot give someone a true indication of how much it will cost to build their ideal home without standing on the land; after all, everyone’s’ block is unique.

What happens at a site inspection
One of our best custom home builders in Sydney meets you at your block of land and discusses your dream home in more detail with you. To ensure we design the right home for you, we want to know more about your family and your lifestyle. In your eyes, what does your dream home look like?

At a site inspection, we consider every aspect of the block including:

  • The slope of the land
  • Location of trees
  • Access
  • Storage space
  • Restrictions
  • Natural site drainage
  • Neighbouring properties


This information provides a better understanding of your site and its requirements, and can be used
to develop a more accurate costing on your new custom home. Once all these things are considered, you’ll have everything to help you make an informed decision moving forward.

At Wincrest Bespoke, each home we design and build is entirely custom made. This means our team of architectural designers will partner with you to design, from the ground up, a stunning one-of a-kind home that’s tailor made to meet the individual needs of your family and land. As such, the cost will depend on the exact design we develop with you, your land and the finishes you select.

Factors to consider when thinking about cost

The single most important factor when building in Sydney is the cost of the land. The projected cost of your build will be site-specific, and can depend on this and a number of other factors. This can include:

  • Site considerations such as land, soil type, sewers and services, and whether tree removal or earthworks may be required.
  • If your land is located in a flood or bushfire zone, or located close to the ocean.
  • The quality and type of fixtures and finishes that you’re seeking.
  • The time frame of when you require your home completed by.
  • Design complexity, for example the number of rooms, walls and layout of the home.
  • Whether you have a sloping site. A custom design can prove invaluable here, as your home can be designed to suit the block rather than the other way around.
  • Local council regulations, which can also have an effect on the final design and cost of the build.


A word on quality

Not only can you expect an entirely bespoke new home when building with us, but you can also expect a higher standard of quality than you might find in a typical new home. As just one example, we prefer to incorporate 75mm Autoclave Aerated Concrete (AAC) flooring. This provides excellent sound insulation for a better acoustic rating and quieter house; plus, its thermal conductivity qualities can improve the energy efficiency of your home.

The importance of experience

If you’re considering a custom home, it’s vital to speak with experienced custom home builders. A true custom builder is one who will design a home specifically for you starting with a blank piece of paper and incorporating all of the features that are important to you. Choose well, and you’ll have a true partner throughout the process.

Our end-to-end management provides the confidence your home will be completed with attention to detail, customer service and after-care. We’ll guide you throughout the design and build of your new home, including initial site inspection, approvals, landscaping, driveways, pool and more.

We also stay ahead of the industry norm to make sure there are many options available for our clients. Innovative building products and materials are constantly being developed, and these can be used to provide alternative options for the construction of your home. We work collaboratively with our team of suppliers to ensure our clients are looked after and have the best choices to select from.

Families come to us when they are looking for a step above the ordinary

Many clients come to us because they have a particular dream home in mind and they can’t find anything that ticks all of their boxes. Others may need help designing a home to suit their uniquely shaped block, or a site with over 1.5 metres of fall. We have extensive expertise building on sites with more than 7 metres of fall, and know how to maximise the outlook and layout on such a block of land.

Keeping discussions about costs clear and honest

No matter whether you are current property owners or first home buyers in NSW, everyone has a build price in mind. Our aim is to be dream makers – not dream breakers, and we’re dedicated to providing high quality design, construction and workmanship to suit your parameters. The build cost only for our most recent projects has started at around $500,000 and up t 1.5 million. The right builder and architectural design team will always plan from the ground up and provide you with a fixed price for a stunning new home that meets your exact requirements.

There is no one-size-fits-all answer to the question of “how much to build a custom home?”, but the advantage of a unique build is that you can perfectly tailor your floor plan to you, your family and your requirements without compromises. It’s this approach that sees happy clients and beautifully personalised homes. With over 30 years’ experience, let the team at Wincrest Bespoke help you design and build the home you’ve always imagined.
