    We are very happy with our build through TRIIIA. It went smoothly and was very quick and we have an excellent finished product. We have already recommended TRIIIA to several of our friends and acquaintances. We went with TRIIIA/Simon after we got a bad feeling with a volume builder on the eve of signing a build contract for a custom version of one of their designs. TRIIIA was recommended to us by someone who had built with them before. Simon helped us restart the build process by putting us in touch with 365 Architects to work up our own design, with TRIIIA then managing the Council approvals process for our design. We then contracted with TRIIIA to build our design. Simon was transparent and very communicative throughout the whole process. We were impressed by the standard inclusions in TRIIIA's specification and went with many of the "standard" items with TRIIIA's suppliers due to their quality and aesthetic. We were impressed with how quickly the build progressed, with there appearing to be work undertaken on site consistently and speedily. We contrasted this with some other builds in our area, which appeared to go for weeks at a time with no activity. Simon was transparent on pricing for upgrades and additional inclusions that we wanted to do as the build was progressing and was very easy to get along with. We are happy that we went with our gut and went with TRIIIA. This was reinforced when our building inspector for the final inspection said that he thought the house was very well built and up there with the best he had seen(!)

    The whole process from beginning to handover of keys was friendly and professional. Simon, the project manager Jess, the trades and suppliers used did an exceptional job to our home. Simon was approachable and the process/cost were kept transparent. We would highly recommend talking to Simon at TRIIIA Builders for your next dream home.

    Simon and the TRIIIA team truly stood out throughout our custom build, guiding us from the initial meeting to the design phase, with Simon as our point of contact and site supervisor until handover. The efficiency, speed and quality of the build were commendable, particularly in the face of the current building industry challenges with delays in trades and materials. In total the build took around 10 months with our slab going down in February and handover in late November. Maintaining open lines of communication, Simon was easily accessible via email or text throughout the duration of the build. Simon maintains great relationships and connections with all involved tradespeople, most of which have worked with him for several years. We also valued the flexibility to engage our own private inspector, whose findings, albeit minor, were promptly addressed by Simon and the trades involved. All additional issues picked up, even during and after handover (as is expected with the many people involved in the building process) were rectified promptly by TRIIIA. Simon shows great pride, care and is a stickler for quality in his work as is showcased on his social media. He has a genuine commitment to maintaining high-quality standards throughout all aspects of the build to ensure that his customers are happy with the end result. In the future, we'd gladly build with TRIIIA once again for any upcoming projects. We truly value the personalised approach that sets Simon and the TRIIIA team apart from other volume builders, ensuring we're “not just a number” but a well looked after priority in every step of the process.

Frequently asked questions

How much do builders typically charge?
Builder costs vary widely depending on the job type and complexity. Minor repairs are generally much less than extensions, small builds or structural alterations that need foundations, framing or specialist input. Most quotes include a call‑out fee plus labour and materials, and the page shows live pricing to help you compare options.
Do builders charge call-out fees?
Call‑out fees are common and typically cover travel and an initial inspection or assessment. This fee is usually separate from hourly labour and materials, and after‑hours or weekend attendance often attracts higher rates. Ask whether a call‑out or minimum charge applies when requesting quotes.
Do builders need a licence in Australia?
Yes. Building work generally needs to be carried out by a licensed builder in every state and territory, and NSW builders are regulated by NSW Fair Trading. Builders should be able to provide their state builder/contractor licence number and show appropriate insurances and ABN/GST registration. In Victoria, domestic building insurance is required above a state threshold for certain contracts.
