Book and appointment to see our new Duplex Design Centre which showcases all the latest duplex trends. We’ll show you how to create both a new home and a new income, by building two stunning homes on a single lot. 



Champion Homes has for many years offered Australian working families looking to build a new home the option of building a duplex on their land.


A Champion Homes Duplex consists of two attached dwellings on a single allotment of land. The Champion Homes Duplex may be sub-divided as either Torrens or Strata Title subject to your councils Local Environmental Plan (LEP) and council approval.


Duplex construction is seen as a low cost way of achieving higher housing density in established older suburbs of Sydney and adding value to the existing home site. Champion Homes has recognized this trend and has over the years built Duplex Homes in a wide range of Sydney Suburbs where Australian working families and investors have decided to maximize the use of their home site by demolishing the existing home and building a Champion Homes Duplex.


Our experience in Duplex Home building has enabled us to advise families and investors on how to maximize the advantages their site has to offer Duplex Construction.

Brief and Budget

This is the first step in establishing your needs and a viable budget for your Duplex. A 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

  • Which way you land falls i.e., to the street or the rear

  • The width of your lot

  • Your lifestyle

  • The size of the Duplex and number of rooms

  • Parking requirements

  • Quality of inclusions in the Duplex

  • Impact on neighbouring properties

  • Viable budget for your duplex

  • Zoning of your lot

Having a well prepared brief will help the 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 determined 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 the site and prepare a site inspection report which will include spot levels, and identification of any constraints to building a duplex on your site.


When the site inspection is completed the Champion Homes drawing office will prepare a suitable sketch based on the client brief and the site inspection report. The preliminary design, once complete will be passed to the Champion Homes pricing office where a tender is prepared based on the design sketch and information taken from the site inspection report.


On completion of the tender the Champion Homes design consultant will arrange to meet with the client to review the design sketch, and the tender. During this meeting the matters to be reviewed and discussed will include an assessment of the design sketch against the original client brief and a discussion of the tender inclusions and pricing.


Once satisfactory agreement can be reached on the design sketch, the tender price and the client signs and accepts the tender, Champion Homes will move to prepare the development application for council submission.


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

  • Storm water 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 through council until a determination has been made by council.


Should council require additional information during their assessment of the application, Champion Homes will provide the requested information.


In conclusion Champion Homes has the experience and knowledge to take care of your duplex development application.
