Champion Homes are Duplex home specialists who have for many years helped Australian working families maximize their properties potential by building a duplex on their land.

Unlock the potential value of your land.

With land becoming increasingly more valuable, we have created The Duplex Design Centre, one of the first of its kind. The Centre showcases all the latest duplex trends and gives you options not previously possible, unlocking your block’s full potential by creating two contemporary dwellings on a single lot.

A Champion Homes duplex consists of two attached dwellings on a single allotment of land.

Subject to your council’s local environmental plan (LEP) and council approval, your duplex home may be subdivided as either Torrens or Strata title.

Champion Homes Puts You Ahead of the Game

Champion Homes was one of the first major builders to recognise this trend and has over the years helped duplex builders (home and land owners) maximise their investment by building duplex homes in a wide range of Sydney suburbs.

Our experience in duplex home building is second to none, this has enabled us to help families and investors to maximize the advantages of their site for duplex construction.

The Process for Building A Duplex Home

Brief and budget

The first step is establishing your needs and a viable budget for your duplex. Your Champion Homes design consultant will help you with this important first step and together you will look at a range of factors in preparing your brief and budget including:

  • The size and orientation of your lot
  • The way your land falls ie: to the street or away
  • The width of your block
  • What is your lifestyle
  • The size of the duplex, number of rooms;
  • Parking requirements
  • Quality of inclusions
  • Potential impact on neighbouring properties
  • A viable budget for your duplex
  • Zoning of your lot

Having a well-prepared brief will help your Champion Homes design consultant assess your duplex requirements against the requirements of your local Council for duplex construction in the local Council area.

Once the Champion Homes design consultant has established that Duplex construction is possible on your lot champion homes will move to the next step.


Preliminary Design and Pricing

The next step will be the preparation of a preliminary design sketch.

Before work on the sketch can commence a Champion Homes site inspector will visit your block and prepare a site inspection report which will include spot levels and identification of any constraints to building a duplex on your land.

When the site inspection is completed the Champion Homes drawing office will prepare a suitable sketch based on your ideal outcomes and the site inspection report.

The preliminary design will then be passed onto the Champion Homes pricing office where a tender is prepared based on the design sketch and information taken from the site inspection report.

Your Duplex Home Tender

On completion of the tender your Champion Homes design consultant will arrange to meet with you to review the design sketch and the tender.

This is an exciting point of progress in your duplex builders project. In this meeting you will review and discuss the design sketch against your original ideas and you’ll discuss the tender inclusions and pricing.

Once you’re ready to go, the design sketch is exactly what you want and you agree on the price that’s when you sign and accept the tender and things really kick into high gear and Champion Holmes duplex builders will move to prepare the development application for council submission.

The Development Application Process for Duplex Builders

For a duplex development application Champion Homes will prepare a full set of architectural plans and the following reports:

  • ABSA assessment report
  • Site analysis report
  • Statement of environmental effects
  • Shadow diagrams
  • Landscape plans
  • Stormwater drainage design
  • Waste management report
  • Colour Schedule
  • BASIX report



When the submission is complete Champion Homes will lodge the development application to Council and track the application until a determination has been made. Should Council require additional information during their assessment of the application Champion Homes will provide the requested information.

Everything is taken care of so you can rest assured the best job possible is being done and relax in the knowledge the Champion Homes duplex builders professionals have it in hand. Champion Homes duplex builders have all the experience and knowledge to take care of your duplex project.
