Frequently Asked Questions

Rest assured we’ve got the answers you’re looking for. Take your time reading through our collection of most commonly asked questions or get in touch with your own questions by completing the form below.


  • Will my new home be energy efficient? Does this cost more?

    All homes must comply with government 6 Star energy regulations. These can change quite regularly; however, all of our home designs comply with the 6 Star rating which equates to more cost effective use of heating/cooling energy, thereby reducing the carbon footprint. We are continually seeking more efficient ways to improve this.

  • What are Provisional Sum items?

    A provisional sum is an amount of money included in the contract sum to cover work or materials, or both, the extent of which cannot be specifically detailed when entering a contract.  Typically, builders will include a PS for sitework costs. The builder is required to take reasonable steps to ensure an accurate site works cost estimate. However, in some circumstances, unforeseen events mean that the provisional sum is exceeded, sometimes by a significant amount. This can be added to the contract sum.

    For example, a building site may seem sandy and clean with minimal siteworks required.  However, there may be large limestone rocks or tree trunks concealed below the surface which only emerge once siteworks commence, causing a considerable cost overrun.

  • What kind of warranties and peace of mind do you offer?

    Ben Trager Homes, while independently run, is part of the SSB Group which has been successfully trading as Content Living for 25 years, with Dreamstart Homes and MOMU also part of the group.

    When you build with Ben Trager Homes you take advantage of the lowest prices available to the market due to buying power and finely honed processes and quality management.

    All homes come with a lifetime structural warranty and a 6 month maintenance period.

  • Should I buy land before contacting a builder, or talk to a builder before I buy land?

    As a custom home builder, our business model is such that we generally work with clients who already own land and we build on their lot.

    However, it can be advantageous to contact a builder while you’re still researching land, as we can help you get a better idea of the kind of land you’ll want to build on.

    Ultimately though, the land you end up with will dictate much about your home’s design. So while it may be obvious that we can’t start building a home until you have a place to build it, what might not be so obvious—but is just as important to know—that we really can’t design a home either until we know exactly what kind of building conditions we’ll have.

    All that to say that generally, you will want to own land before you start talking to a builder about design and pricing. If you’re interested, we can work with you and one of our lending partners to bundle your loan for the land and your construction loan, so feel free to contact us if that’s what you’d like to do. Also, if you don’t have a realtor yet, feel free to contact us and we’ll connect you with one of our preferred real estate agents who can help you find land.

  • Exactly what is my home made from?

    Our single storey homes are all built with double leaf clay brick walls with timber roof frames. This is the traditional and most popular and cost effective method of building single storey homes in Perth.

    Our double storey homes are constructed of double leaf clay brick to the lower floor external walls, single leaf clay brick to lower floor internal walls.  A steel truss system and concrete slab create the upper floor.  The upper floor external walls are built on site by a carpenter from timber which is then clad with a closed cell EPS (Expanded Polystyrene) board that is coated in acrylic render.

  • What are the advantages to light weight upper walls?

    Resilient and lightweight, EPS has been designed specifically for the external cladding of homes, with its exceptional thermal properties providing superior wall insulation. There are no prefabricated sections that need to be transported and therefore the design to upper floors is as flexible if not MORE flexible than a double brick home.

  • Can I make alterations to the standard designs?

    Absolutely! We welcome changes and ideas to our standard plans and even provide a professional design & drafting service. Complete individual designs are also very common and we enjoy taking your ideas and making them a reality. Speak to your Ben Trager Homes Building Consultant to learn the latest on typical build times.

  • How long does it take to build a new home?

    It is in everyone’s best interest to complete the build as quickly as possible, while not forsaking quality and good workmanship to do so.  The Perth building market also impacts on build times.  Speak to your Ben Trager Homes Building Consultant to learn the latest on typical build times.
