  44 Ways #26: Choose for Longevity and Durability 01.10.2026 16mnt

  Hello! This is Episode 426. This is Way #26 of the 44 Ways to Create Your Sustainable Home series, and we’re beginning Section Six: Choosing Materials, Fixtures and Finishes. Way #26 is: Choose for Longevity and Durability. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/426] The last couple of sections have been detail-heavy and chunkier episodes, especially as I’ve talked about the building envelope, because it’s where a lot of the technical decisions in your home happen. Section 6 takes us back to our shorter, punchier episodes.  In each, I’ll be covering one specific criteria for choosing materials and products for both the interior and exterior of your future home. This will give you a roadmap for thinking about your sustainable choices when making material, product, fixture and finish selections for your renovation or new build.

  44 Ways #25: Include Eaves and Window Hoods in Your Finished Home 28.09.2026 27mnt

  Hello! This is Episode 425. This is Way #25 of the 44 Ways to Create Your Sustainable Home series, and it’s the last episode in Section Five: The Building Envelope. Over this section we’ve worked through airtightness, windows, building wraps, and insulation. In this episode, we discuss something that can elevate the performance of your building envelope very simply. Way #25 is: Include Eaves and Window Hoods in Your Finished Home. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/425] This episode pulls together two concepts: the information about designing for the orientation of your site that I shared back in Way #1, Episode 401, our first episode of the ‘44 Ways’ series, and the discussions we’ve been having in this section about the building envelope. Because once you understand how the sun moves across your site, the next question is about how your building envelope is designed to provide the protection you need from the elements on your site. And that’s what eaves, hoods and awnings can provide.

  44 Ways #24: Install Insulation Correctly 24.09.2026 22mnt

  Hello! This is Episode 424. This is Way #24 of the 44 Ways to Create Your Sustainable Home series, and we’re in the final stretch of Section Five: The Building Envelope. In the last episode, we went through the types of insulation, what R-values mean, and how to think about products for your ceiling, walls, and floor.  This episode is the follow-up to that: what happens when the product is specified, the quote is signed, and the installer shows up. Because that’s where a lot of the thermal performance of a home is either delivered or lost. Way #24 is: Install Insulation Correctly. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/424] Did you know that a 5% gap in your insulation coverage can reduce its effectiveness by up to 50%?  So, you can invest money in specifying the right product, achieving the right R-value, choosing the right type for your climate, and testing it through modelling. And all of that work can be significantly undermined by how the product is installed.  And unfortunately, once the building is lined, any rectification becomes more challenging.

  44 Ways #23: Choose Appropriate Insulation 21.09.2026 29mnt

  Hello! This is Episode 423. This is Way #23 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope.   Way #23 is: Choose Appropriate Insulation. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/423] The things we’ve been discussing in Section Five are all about improving the energy efficiency of your future home, whilst also supporting its durability, longevity, and the contribution it makes to your health and well-being in your home, through the choices in how you assess, test and specify your building envelope. Over the past few episodes, we’ve covered airtightness, window selection, and how to choose the right building wrap for your climate. This episode is about insulation: the various types and what to know about how it works. Insulation has been part of home construction for decades, and as energy efficiency benchmarks have become part of building and renovating, insulation has been adopted as a worthwhile investment to help reduce the cost of heating and cooling homes.  We’ve done a great job of improving the insulation in our homes over the years, understanding it improves our home’s thermal performance.  But how much insulation do you really need? And where, and what type? In this episode, I share more with you as we go through why insulation matters, what to measure and consider, why adding more insulation may be counterproductive, and how to think about the roof, ceiling, walls and floor of your home for the best outcome.

  44 Ways #22: Review Building Wraps to Manage Moisture for Climate 17.09.2026 26mnt

  Hello! This is Episode 422. This is Way #22 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope. In the last two episodes, we covered thermal mass and window selection. Before that, in Way #19, we talked about what building tight actually means: why you want a continuous air barrier, and why airtightness and ventilation have to be designed together. This episode is about a layer that sits within the wall and roof assembly of your home: the building wrap. Way #22 is: Review Building Wraps to Manage Moisture for Climate. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/422] Historically, especially in Australia, we’ve seen foil sarking act as this layer.  However, with learnings over time about how this has detrimentally affected the performance of the building envelope, as well as how it has trapped moisture inside the wall, bringing issues such as mould and rot, better products are now available to do this job.  Yet, the industry isn’t up to speed with this, and in some cases, is still installing the wrong building membranes, and using the wrong detailing, which continues to create long-term issues. Getting it right with building wraps involves knowledge of building science and construction detailing, and your climate and construction methodology is key to ensuring the best solution for your project.  So, what I’m sharing in this episode will get you started, but it’s super important to be discussing this in detail with your team. Don’t assume that, just because it’s in the local building regulations, your team is across it.

  44 Ways #21: Review Your Window Selection 14.09.2026 27mnt

  Hello! This is Episode 421. This is Way #21 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope. Way #21 is: Review Your Window Selection. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/421] In my experience, as people go to design their new build or renovation, it can be all about maximising the indoor / outdoor connection, and having a home that feels light-filled and expansive.  And so, the glass windows and doors you choose, in their size, arrangement, design, functionality and type, all become really important decisions in achieving this in your home. And, they’re likely to take a big chunk of your building budget. However, glass windows and doors are also where the majority of uncontrolled heat gain and heat loss happens in a home. They sit at the intersection of the envelope performance issues we’re covering in this section: thermal performance, ventilation, airtightness, and moisture management.  And yet, most homeowners haven’t been given the information they need to make deliberate choices about them. In this episode I focus on the envelope performance side: thermal properties, airtightness, and ventilation. Because when you’re thinking about your glass windows and doors, you’re possibly not asking questions about these things, and they’ll make the biggest difference to how your home performs.  As always, if you'd like to access a full transcript of this episode and links to any resources I mention, head to www.undercoverarchitect.com/421.

  44 Ways #20: Use Thermal Mass to Maintain Even Temperatures 10.09.2026 18mnt

  Hello! This is Episode 420. This is Way #20 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope, A Sustainable Skin. In the last episode, Way #19, we covered airtightness and ventilation. We talked about what it means to build tight, why homes don’t need to breathe, and what ‘ventilating right’ looks like in practice. In this episode, we’re looking at one of the most commonly discussed, and commonly misunderstood, elements of the building envelope: thermal mass. Way #20 is: Use Thermal Mass to Maintain Even Temperatures. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/420] You’ll hear architects, builders and sustainability consultants talk about thermal mass as a worthwhile inclusion in any home. This can include concrete slabs, brick walls, rammed earth, and other ‘heavy’ forms of construction.  Even water-filled features are used as thermal mass in homes.  Thermal mass is a powerful tool when the conditions support it, and it’s designed with the right approach for the climate and site. However, when those conditions aren’t in place, it can make your home harder to heat, harder to cool, and less comfortable overall. In this episode, I take you through what thermal mass actually is and how it works, the three conditions that need to be in place for it to function well, when thermal mass will work against you, why the ground your slab sits on and the finish that covers it matter just as much, and what to ask your team.

  44 Ways #19: Build Tight, Ventilate Right 07.09.2026 22mnt

  Hello! This is Episode 419. This is Way #19 of the 44 Ways to Create Your Sustainable Home series, and it’s the first episode in Section Five: The Building Envelope. We’ve spent four sections of the ‘44 Ways’ series covering a lot of information for your sustainable renovation or new build. Site, orientation, breezes, passive design, energy and water selections, renewables, and the tools that help you model and measure how your home will actually perform. All of that work is most valuable when the building envelope itself is doing its job well. This is Way #19: Build Tight, Ventilate Right. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/419] Section Five is about creating a sustainable skin in your building envelope. The skin of your building (your floors, walls and roof) is supposed to protect and shelter you. There’s a science to how it can do this well.  And when you understand how vapour, moisture and temperature move from the inside to the outside of your home (and vice versa), you’ll learn it’s important to design and build a building envelope that suits your climate, mitigates the risk of mould growth, helps maintain comfortable indoor air temperatures, and that is durable and long-lasting. I want to start by taking on one of the most persistent myths in residential construction. The idea that homes need to breathe. Our homes don’t need to breathe. The people inside them do. And they need to ideally breathe fresh, unpolluted air, whatever the weather or conditions outside their home. In this episode, I take you through what the phrase ‘build tight, ventilate right’ actually means, what a ‘breathing’ home is often confused with, what building tight looks like in practice (and how tight is tight), why relying on opening windows alone often isn’t enough, and what mechanical ventilation with heat recovery (MVHR) adds in a high-performance home.

  44 Ways #18: Measure Your Home’s Carbon Footprint 03.09.2026 22mnt

  Hello! This is Episode 418. This is Way #18 of the ‘44 Ways to Create Your Sustainable Home’ series. And this episode completes Section Four: Modelling and Measuring Your Sustainability. Across this series, we’ve talked a lot about energy efficiency, and how, as we improve energy efficiency, we reduce energy use, which in turn reduces the carbon emissions associated with energy production.  At the same time, we’ve got better at measuring the embodied carbon in construction. Embodied carbon represents the greenhouse gas emissions associated with extracting and creating materials, and construction and deconstruction itself. This is the carbon footprint of the home, and it’s increasingly being seen as the required area of focus to reduce the impact this industry has on the climate. Way #18 is: Measure Your Home’s Carbon Footprint. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/418] In this episode, I take you through what operational and embodied carbon mean, why embodied carbon is becoming an increasingly significant part of the picture, and, if your carbon footprint is a sustainability consideration for your renovation or building project, what you can do about it during design, and the conversations to have with your team.

  44 Ways #17: Get a WUFI Analysis Done on Your Floors, Walls and Roof 31.08.2026 18mnt

  Hello! This is Episode 417. This is Way #17 of the ‘44 Ways to Create Your Sustainable Home’ series, and we’re continuing through Section Four: Modelling and Measuring Your Sustainability. If you’ve been following this series, you’ll know we’ve spent the last couple of episodes looking at energy modelling, and how you can use it during the design process so its data-based findings can inform your design as it develops. Way #17 is: Get a WUFI Analysis Done on Your Floors, Walls and Roof. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/417] As well as the positive benefits of energy efficiency and thermal comfort that airtightness and well-insulated homes can bring, there can be a negative consequence of building this way that needs to be managed. When you seal a building up tightly, and you insulate it well, moisture behaves differently than it does in a leaky home.  And if the way your walls, roof and floors are put together hasn’t been thought through carefully from a moisture perspective, you can end up with a problem that develops silently inside your building fabric over years, until it becomes very hard and expensive to fix. If you’ve never heard the word ‘WUFI’ before, this episode will introduce you to a tool that most of the residential building industry isn’t routinely using or talking about, but that is increasingly important from a risk-management perspective as we build more airtight and better insulated homes.

  44 Ways #16: Use Other Options to Model Your Design Before You Build 27.08.2026 22mnt

  Hello! This is Episode 416. This is Way #16 of the ‘44 Ways to Create Your Sustainable Home’ series, and we’re continuing through Section Four: Modelling and Measuring Your Sustainability. Way #16 is: Use Other Options to Model Your Design Before You Build. In the last episode, I talked about NatHERS energy modelling and why it can be so valuable as a design tool rather than simply using it as a late-stage compliance exercise.  In this episode, I want to explore that further, because the required modelling tool for your region may not be all that’s available to you. And for projects where you’re aiming for high performance, it may also not always be the most comprehensive one. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/416] Think of this as a set of tools that help you understand how your home will perform before you build it, so you can make better decisions with your money while change is still cheap. That’s it. Some tools are required legally, such as NatHERS in Australia. Others are optional, available as another measure, data source or audit process. I also want to address something that comes up a lot in the Undercover Architect community: the idea that NatHERS and Passive House are in competition, and that you have to be in one camp or the other. It really doesn’t need to be that way. Think of it as a spectrum. And so, in this episode, I take you through Passive House modelling and what you can learn from it even if you’re not pursuing Passive House certification, how this modelling approach might give you a more complete picture of your home’s performance, and how to think about the Passive House principles themselves as a design framework, separate from the question of certification. I also share some other valuable modelling tools that may assist you in your project, whether you’re renovating or building new.

  44 Ways #15: Use Energy Modelling During the Design Phase 24.08.2026 22mnt

  Hello! This is Episode 415. This is Way #15 of the ‘44 Ways to Create Your Sustainable Home’ series. And with this episode, we begin Section Four: Modelling and Measuring Your Sustainability. In Section Four, we look at the ways you can access data to inform your decision-making, beginning with energy efficiency assessments and modelling of your home’s energy use. We’re beginning Section Four with Way #15: Use Energy Modelling During the Design Phase. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/415] If you’re based in Australia, you’ve possibly heard the phrase ‘NatHERS star rating’ somewhere in research conversations about your project. In other locations, you may have heard about star ratings, or energy efficiency ratings required as part of the compliance process in your project. In most locations, energy efficiency assessment occurs after documentation is completed, as part of finalising building approvals prior to construction. Sometimes homeowners are not even aware of it as a step, until the builder or designer has taken care of it, and they’re presented with the report it outputs.  However, when left until that point of your project, after your design is locked in, you’re underutilising the benefit of energy modelling to your project and future home, and it’s potentially costing you money, comfort, and sustainability performance every day. Energy efficiency modelling can be used as a design tool, and when treated as such, there’s an opportunity to use it to improve your design, rather than just tick a box. In this episode, I take you through what NatHERS and other types of energy modelling actually are, how they’re typically used in projects compared to how they can be used, what star ratings really mean for your home’s performance, and the questions to put to your team to make sure modelling is doing real work for you, not just being ticked off as a compliance requirement.

  44 Ways #14: Use Renewable Energy to Supply Your (Reduced) Energy Needs 02.07.2026 20mnt

  Hello! This is Episode 414. This is Way #14 of the 44 Ways to Create Your Sustainable Home series. And this episode completes Section Three: Sustainable Services and Infrastructure. It may seem strange that we’ve taken a while to get here, given this is where many homeowners will start in their sustainability choices for their project. ‘Let’s make sure we put solar on the house when we renovate or build new’ is a sustainability move many will make. Way #14 is: Use Renewable Energy to Supply Your (Reduced) Energy Needs.  Note the inclusion of the word ‘reduced’ there, because that’s your first priority, and then your renewable energy can supply that lower need. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/414] Now, I understand why solar feels like the obvious first move for many homeowners. It’s visible. It’s tangible. Its benefits show up on the electricity bill. And with rebates offered in many locations to offset the installation costs, they can be an attractive incentive to include. But if you’re doing whatever you want in your home design and layout, ignoring the site and climate, and adding solar before you’ve addressed the energy efficiency of the home itself, well, you’ve possibly heard the saying: it’s like putting lipstick on a pig. Instead, when renewable energy is used in collaboration with design measures that improve the efficiency of your home, it can be a really great way to achieve sustainability overall.  In this episode, I take you through the common mistake homeowners make when it comes to renewable energy, why going all-electric is the prerequisite for running your home on 100% renewable power, what rooftop solar actually involves and how to think about sizing and storage, and the sequence that gives you the best sustainability outcome at the lowest overall cost.

  44 Ways #13: Select an Efficient Hot Water Unit and Get the Plumbing Layout Right 29.06.2026 20mnt

  Hello! This is Episode 413. This is Way #13 of the ‘44 Ways to Create Your Sustainable Home’ series. And we’re still in Section Three: Sustainable Services and Infrastructure, and reviewing our hot water supply. For many homeowners, their decisions about their hot water unit can come in a flurry, and simply be based on what they know. Sometimes it can be handed to the plumber, as they recommend a system, you go with it.  However, your hot water unit is a product that can last ten to fifteen years, and the selection you make locks in a significant amount of energy use and money each year you live in your home, so it’s worth considering the options before you specify. Way #13 is: Select an Efficient Hot Water Unit and Get the Plumbing Layout Right. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/413] Hot water accounts for approximately 23% to 25% of your home’s total energy use. That makes it the second largest energy consumer in your home after heating and cooling. In this episode, we’ll talk about the key differences between the main hot water system types, what to consider and avoid, why heat pump hot water units sometimes get a bad reputation and what the reality actually is, the plumbing layout decisions that can significantly reduce hot water waste, and the specific discussions to have with your team.

  44 Ways #12: Store and Reuse Water for Greater Water Saving 25.06.2026 21mnt

  Hello! This is Episode 412. This is Way #12 of the 44 Ways to Create Your Sustainable Home series. We’re continuing through Section Three: Sustainable Services and Infrastructure. In Episode 411, we looked at where household water goes, especially in indoor use, and how to reduce consumption through fixture selection and design decisions.  In this episode, we’re looking at the other side of that equation: not just using less water, but capturing and reusing the water that falls on and around your home. Way #12 is: Store and Reuse Water for Greater Water Saving. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/412] In this episode, I share information on rainwater harvesting, greywater systems, and what it looks like to meaningfully reduce, or in some cases almost eliminate, your home’s reliance on mains water for outdoor use. I’ll also share a little of my own experience with whole-of-home rainwater supply, as we’ve been living entirely on rainwater for over a decade now.

  44 Ways #11: Reduce Your Water Use In and Around Your Home 22.06.2026 18mnt

  Hello! This is Episode 411. This is Way #11 of the 44 Ways to Create Your Sustainable Home series. We’re continuing through Section Three: Sustainable Services and Infrastructure, and today we’re looking at water. In the last episode, we covered Way #10: reducing your energy use through your selections. In this episode, we’re looking at water efficiency. Where does water really get used in your home? What do the ratings mean in practice? And what decisions, beyond just choosing efficient fixtures, can actually make a difference? Way #11 is: Reduce Your Water Use In and Around Your Home. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/411] Water tends to receive less attention than energy in a sustainability brief. I think this is partly because the financial feedback is less immediate. Electricity bills arrive more regularly and can feel significant. Water bills are often quarterly, and in many areas they feel manageable, or are wrapped up with your council fees.  But around 12% of Australia’s water use is in residential homes. Water is a finite resource, and under pressure in many locations around the world, and the decisions you make about how your home uses it can carry through for the life of the home. Interestingly, water efficiency can be one of the most straightforward areas to address, purely through specification. The ratings systems that exist for water-efficient fixtures are clear and accessible. The products are widely available. And in most cases, the cost difference between a high-efficiency and a standard fixture at specification stage is minimal, while the savings over time are significant. In this episode, I take you through where household water actually goes, what the rating systems mean in practice, the design decisions beyond fixture selection that can reduce water use, and why outdoor water use deserves its own conversation, which we’ll cover in the next episode.

  44 Ways #10: Reduce Your Energy Use Through Your Selections 18.06.2026 17mnt

  Hello! This is Episode 410. This is Way #10 of the 44 Ways to Create Your Sustainable Home series. And with this episode, we also begin Section Three: Sustainable Services and Infrastructure. If you’ve been following the series from the start, you’ll know that Section One was about designing for climate and site: orientation, breezes, passive heating and cooling, and climate zone.  Section Two was about sustainable design strategies: home size, your team, structural efficiency, accessibility, and indoor air quality. We’re beginning Section Three with Way #10: Reduce Your Energy Use Through Your Selections. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/410] In the first 9 episodes of the ‘44 Ways’ series, I’ve stepped you through some key decisions that will shape the sustainability of your new home or renovation before any system is installed in it. Section Three is where we look at the services and infrastructure inside your home. Think energy, water, hot water, and renewable supply. Interestingly, these areas are often where people start their sustainability conversations, as they can feel much more tangible than the project initiation and design decisions we’ve been discussing up to this point. They’re the actual systems that determine how your home runs day to day, how much it uses in resources, and what it costs to run. In this episode, I take you through where your home’s energy is actually being spent, how to approach appliance and system selection for efficiency, how to correctly size your mechanical heating and cooling systems, and the hierarchy that I think every homeowner should have in mind when making these decisions.

  44 Ways #09: Improve Your Indoor Air Quality 15.06.2026 20mnt

  Hello! This is Episode 409. This is Way #9 of the 44 Ways to Create Your Sustainable Home series. This episode also closes out Section Two: Sustainable Design Strategies. In this episode, we’re finishing Section Two with Way #9. Way #9 is: Improve Your Indoor Air Quality. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/409] The ways I’ve been sharing in Section Two have been about the bigger-picture design decisions that need to be thought about early, but can create a huge amount of impact in your future home’s sustainability, functionality and performance.  We’ve covered designing a smaller, smarter home, choosing an aligned team, creating an efficient structural design collaboratively, and future proofing your home with accessibility. I know that when most people think about sustainability, they’re thinking about energy, water, and materials, and how they can save all of those things. But a sustainable home is also a healthy home.  And, given that we spend 80 to 90% of our time indoors, and especially since COVID, much of that time is now in our homes. The quality of indoor air that your renovation or new build creates will have a big impact on the health of all living in the home, and how the home functions for you long-term. Indoor air quality is directly impacted by decisions you make about the materials and finishes you include in your home, and the ventilation strategy you adopt. Those decisions are ideally made during design and specification.  If indoor air quality is important to you, your goals for it belong in your Design Brief, right alongside other strategic design and specification decisions you want to prioritise in your project. In this episode, I take you through how indoor air quality is part of your sustainability considerations, the main sources of indoor air pollution in residential homes, how moisture and ventilation connect to this, and what you can actually do at the design and specification stage.

  44 Ways #08: Future Proof Your Design with Accessibility 11.06.2026 15mnt

  Hello! This is Episode 408. This is Way #8 of the 44 Ways to Create Your Sustainable Home series. We are in Section Two: Sustainable Design Strategies. The ways I include in this section are about the strategic design decisions that have consequences well beyond the immediate project, and Way #8 is a strong example of that. Way #8 is Future Proofing Your Design with Accessibility. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/408] I want to start by saying that the word ‘accessibility’ comes with a lot of connotations for some people, and it can immediately bring to mind images of hospital-grade handrails, institutional flooring, and design that feels clinical rather than inclusions you’ll happily consider for your future home. However, that is not what accessible design means, and it is not what this episode is about. What it is about is designing a home that works well for people, at every age and stage of life, without requiring expensive modification when circumstances change. And the design features that achieve that are, in most cases, simply good design that support the longevity, durability and ease of use of your home, whether you’re building new or renovating. In this episode, I take you through what accessible design actually means in a residential context, the case for including it from the brief stage, the specific features worth considering in your project, and how to approach it with your design team.

  44 Ways #07: Create an Efficient Structural Design, Collaboratively 08.06.2026 18mnt

  Hello! This is Episode 407. This is Way #7 of the 44 Ways to Create Your Sustainable Home series, and we are continuing through Section Two: Sustainable Design Strategies. The ways in Section Two are about the bigger-picture decisions that shape a project from a strategic level, before we get into the detail of specific systems, materials, or construction. Way #7 is Creating an Efficient Structural Design, Collaboratively. [For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/407] In the last episode, we covered the importance of choosing an aligned team.  This episode is about something that your aligned team needs to do together: create a structural design that is genuinely efficient.  This Way #7 tends to surprise homeowners, because structural design often feels like something that happens in the background of a project and rarely gets discussed with the client directly. But the decisions made around your home’s structural design have direct consequences for cost, material use, durability and longevity, and consequently, the sustainability of your finished home. Whether those decisions are made in the most efficient way usually comes down to one thing: when and how your designer or architect and structural engineer collaborate and integrate their work. In this episode, I take you through what structural efficiency actually means, why it typically doesn’t happen by default, what collaborative structural design looks like in practice, and the questions worth raising with your own team.
