• Building Better: Passive Houses and Sustainable Construction with Josh Atkins

  We recently sat down with our very first international guest Josh Atkins from New Zealand. Of course one of the big things we wanted to know is how construction methods vary between New Zealand and Australia. We discuss the different challenges in climate, legislation and more, that builders face in each country.Josh shared the infamous water damage issues they faced there, and how it forced them to adopt better building practices, including rethinking thermal envelopes and using advanced membranes.It's a chance for us in Australia to learn and anticipate potential challenges.Josh highlighted some of the real challenges in our industry, like transitioning from traditional building approaches to ones rooted in building science and efficiency. We all agree that there's sadly a lot of negativity surrounding building, with concerns about costs and dodgy builders making headlines more than good news stories.There’s also the ongoing battle in construction management—trying to run a smooth business while juggling the ups and downs. Last year was tough for many, with jobs dropping off due to economic conditions and the challenge of staying on top of costs and retaining clients interested in sustainable projects.We've realised that to survive and thrive in this space, it’s crucial to consistently promote what we do—building high-performance homes. As builders, it's not just about building better but also convincing clients of the value these buildings offer.Creating a brand that's associated with quality and sustainability is key. It helps clients understand what you're about even before they meet you. This way, when they come to you, they're already on board with the idea of building better.Finally we touched on the delicate topic of relationships between architects and builders. Often, builders understand practical implementation better, which can lead to tension but things are getting better. More architects are becoming aware of design performance issues, and the insights that builders can offer them. Our chat with Josh was a good reminder that sustainable building is not just a trend but a necessity. By sharing knowledge, we're all working towards the same goal - creating homes that last and contribute positively to the environment.LINKS:Connect with us on Instagram: @themindfulbuilderpodConnect with Hamish:Instagram: @sanctumhomesWebsite: www.yoursanctum.com.au/Connect with Matt: Instagram: @carlandconstructionsWebsite: www.carlandconstructions.com/

• Prefabrication in construction

  Prefabrication can get a bad wrap in the sustainable building world but when used in the right way, it can be a powerful tool for building sustainable and affordable homes. We recently sat down with prefabrication pioneers Chris Gilbert and Kaia McCarty Smith to discuss how it can support a better building future. Chris is the co-founder of Candour, a prefabrication company that aims to address the challenges faced by builders and architects. Unlike typical prefab companies, Candour doesn't focus on volumetric prefabs but rather on a panelised fabrication with a significant emphasis on software development. This means they aren’t just building physical structures; they're also building digital solutions that help bridge the gap between architects and fabricators.Their unique software ties seamlessly into common architectural tools like Archicad, providing real-time pricing and fabrication limits. This ensures architects design structures within practical and budget-friendly bounds, ultimately reducing costs and improving efficiencies from the start.On the other hand, Kaia shared his experience using prefabs as a builder and the force behind Wilderness Building Co. He explained that prefabrication offers a streamlined, efficient, and precise way to construct, with benefits in controlling quality and reducing on-site errors. These advantages are crucial, especially when considering issues like labour costs and the need for quicker building timelines.As builders, we've always been aware of the resistance to change in our industry. Australians, by nature, are wary of deviating from traditional building norms. But is it time to embrace prefabrication fully? Chris believes that while prefab isn’t the silver bullet, it’s certainly part of the solution. Matt also brought up the rising costs of labour, and the difficulties that causes in the Australian market. Automating processes, as prefabrication allows, might be a great solution. However, it’s also about ensuring buildings remain affordable and comfortable for everyone, which continues to be a complex balancing act.So, whether you’re an architect, builder, or part of the wider construction community, it’s time to consider prefabrication. It might not be the complete answer, but it could be a big step towards a sustainable future for construction.

• Architecture is a design weapon for good

  That’s the world architect Jeremy McLeod is fighting for, and he joins us today to share the how and the why behind this dream. Jeremy is the co founder of both Breathe Architecture and Nightingale Housing, where he works to bring sustainability, community, and innovation to the forefront of the building industry. A big focus in our conversation was the Nightingale Model. Jeremy explained that Nightingale isn’t just a building; it's a housing model. At its core, it follows a triple-bottom-line approach, encompassing sustainability, community, and financial feasibility. This involves:- Achieving sustainability through all-electric, 100% renewable energy usage.- Fostering community by sharing resources like laundries and rooftop spaces.- Ensuring financial sustainability by structuring projects around impact investments and selling units without profit margins.Jeremy stated that by removing the profit motive and focusing on community needs and sustainability, Nightingale creates affordable, quality housing. This is evidenced by their growing waiting lists, demonstrating a strong demand for such innovative models.We also discussed the critical role developers play in expanding sustainable housing. Jeremy believes that developers can and should evolve by adopting sustainable practices proven by models like Nightingale. He acknowledged that while profit is not the primary focus for Nightingale, larger developers can still profit through improved environmental standards.Despite the obstacles, Jeremy remains optimistic about change. One of the main takeaways here is that transparency and certainty in planning are vital. Cities can learn from international examples where clear height and density regulations provide more predictable outcomes for developers and communities, which leads to better practices and more innovation! Jeremy is doing some incredible work, and we hope our conversation with him will encourage more people to go out and fight for a better future in building!LINKS:Connect with us on Instagram: @themindfulbuilderpodConnect with Hamish:Instagram: @sanctumhomesWebsite: www.yoursanctum.com.au/Connect with Matt: Instagram: @carlandconstructionsWebsite: www.carlandconstructions.com/

• Building, drying and venting your cavities

  What is a Ventilated Cavity?In simple terms, a ventilated cavity is an air space between the cladding of a building and its structure. This space allows the building to "breathe," circulating air and carrying moisture away. This is crucial to avoid issues like mould, rot, and other moisture-related problems. It’s a technical topic which is why we’re once again joined by Dr Cameron Munroe, who breaks down the nitty gritty of ventilated cavities. Cam explained that inheating-dependant climates like Melbourne or Canberra, building materials need to allow water vapour to escape. Unfortunately, traditional methods sometimes trap this vapour. A ventilated cavity helps in solving this by moving vapour out through a well-ventilated air space.We've noticed and discussed how modern weatherboards differ from older ones. The primary reason? Changes in building techniques and materials. Old hardwoods have been replaced with softwoods, which absorb more moisture and have less tolerance. With improved insulation, drying potential decreases, making material choice vital for moisture management.Different cladding types may require varied cavity depths for effective drainage and ventilation. It's essential to consider both ventilation (for air/moisture) and drainage (for liquid water). Thickness of battens used in cavities needs attention, as they play a role in air circulation and moisture drainage.Cameron suggests that while small gaps can handle drainage, air circulation requires larger cavities. Achieving the right balance between these is key in construction.So how do you choose the right cladding material for your climate? Well, buildings in colder regions require more consideration in cladding and batten selection to prevent moisture issues. We can model these factors to make informed decisions about batten thickness and design.1. Cavity Depths: Consider a standardised cavity size, like a 70mm, which can work across various applications and climates.2. Drainage vs Ventilation: Focus on creating effective drainage and ventilation solutions. Think about using metal mesh for venting and drainage to prevent clogging while allowing air to flow freely.3. Durability of Materials: Choose materials designed to withstand climate changes and prevent long-term degradation.It’s also important to remember that your roof is essentially a wall at an angle. So, similar principles of ventilation and drainage apply. Make sure your roofing system is designed to handle moisture effectively. Avoid using products like Anticon under roof sheets as they can degrade over time and block airflow.So make sure you’re considering the climate and how it'll impact moisture and heat within your building's interior. Ensure you have the right ventilation and drainage strategy to manage moisture efficiently!LINKS:Connect with us on Instagram: @themindfulbuilderpodConnect with Hamish:Instagram: @sanctumhomesWebsite: www.yoursanctum.com.au/Connect with Matt: Instagram: @carlandconstructionsWebsite: www.carlandconstructions.com/
