    We are in love with our new family home designed by Leanhaus. Ben's vision for our block was outside of the box compared to your standard project builder and the choice to go with Leanhaus was absolutely the right one! Ben's partnership with Saltus Built to execute his vision really help make the entire build process enjoyable. We have ended up with a healthy, thermally efficient and beautiful house.

    ⭐⭐⭐⭐⭐ I am delighted to recommend Ben Caine from Leanhaus. As someone who has had the privilege of observing Ben build two of his own houses, I can confidently say that his passion for sustainable and energy-efficient design is truly remarkable. From the initial stages of design to the final construction, Ben's commitment to lean design principles was evident. He meticulously planned every detail, ensuring minimal use of materials without compromising on quality or aesthetics. His designs were not just beautiful, but also functional and environmentally friendly. What struck me most about Ben's approach was the flexibility of his designs. He built his homes in such a way that they could easily be adapted for different purposes - a home office, an extra bedroom, or even a self-contained apartment. This level of adaptability is a testament to his forward-thinking approach. But what truly sets Ben's homes apart are their sustainability features. Built to passive house standards, they are equipped with heat recovery ventilation systems that maintain a constant level of humidity and temperature inside. This makes the homes incredibly comfortable to live in, regardless of the season. Moreover, Ben's homes are not just energy-efficient; they're also healthy. The constant supply of fresh, filtered, and preconditioned air significantly improves the indoor air quality, reducing concerns about dust, mould, or CO2. In conclusion, if you're considering building a passive house, I highly recommend Ben Caine from Leanhaus Architecture. His expertise in solar passive design and his commitment to creating healthy and sustainable buildings are truly unparalleled. With Ben, you're not just getting an architect; you're getting a partner who will bring your dream home to life with utmost care and professionalism.

    Ben provides excellent information on his passive houses on YouTube and his website. I am looking forward to engaging him when I build my next home.

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.
