The Process for Building A Duplex Home

Brief and budget

The first step is establishing your needs 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 including:

  • The size and orientation of your lot
  • The way your land falls ie: to or from the street
  • The size of the duplex, including the number of rooms
  • On-site parking requirements
  • The size of the duplex, number of rooms;
  • Parking requirements
  • Potential impact on neighbouring properties
  • Quality of inclusions
  • 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 may be 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 concept design.

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

When the site inspection is completed the Champion Homes architectural drawing team will prepare a suitable concept design based on your ideal outcomes and the site inspection report and having regard to the relevant development controls.

The concept design will then be passed onto the Champion Homes estimating department where a tender is prepared based on the design and other information available at the time.

Your Duplex Home Tender

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

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

Once you’re ready to go, the concept design is exactly what you want and you agree on the price that’s when you sign and accept the tender.

Champion Homes then will prepare the building contract based on the HIA standard contract. After you have reviewed and signed the contract Champion Holmes duplex builders will begin preparation of 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
  • Concept landscape plans
  • Stormwater drainage design
  • Waste management report
  • External colours and materials 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 endeavour to provide the requested information and deal with any Council queries.

You can rest assured that Champion Homes duplex builders have the necessary experience and knowledge to take care of your duplex project and guide you through the process.
