[https://www.buzzsprout.com/2470783/fan_mail/new] What happens when a commercial construction veteran with a five-hundred-million-dollar mixed-use project on his resume gets taken down by mold? In this episode, Ashley sits down with Dylan Hutcheson, healthy home builder and founder of Holistically Built in Atlanta, Georgia, whose path from high-rise construction management to residential healthy home construction runs straight through two years of mystery illness, medical leave, a disability insurance lawsuit, and a slow, humbling rebuild of his health and his career. Dylan brings something rare to the healthy home conversation: deep mechanical systems knowledge earned not just from building but from years of tearing sick buildings apart and figuring out why they failed. Together Ashley and Dylan walk through the mechanical systems conversation this space has been waiting for, from why oversizing an HVAC unit is one of the most common and expensive mistakes in hot humid climates, to what ductboard actually is and why one of Atlanta's top ENT doctors will not see patients who still have it in their homes. They dig into manual J, S, D, and T calculations, why a dehumidifier is sometimes a necessary evil and sometimes misunderstood, how ERVs interact with the rest of your system, and why the IQ Air Perfect 16 filter may be one of the most underrated upgrades available for an existing home. They also talk about planning ahead, collision plans for mechanical and structural coordination, roof geometry, window placement, and all the decisions that cost you almost nothing to think about in design and a fortune to fix in the field. This is a part one, and they are already planning part two around what it actually looks like to build Dylan's own home from scratch.

After a career in large-scale commercial construction with Brasfield and Gorrie, Dylan was sidelined by a serious environmental illness that took years to recover from. That experience led him to environmental consulting, where he spent years conducting indoor air quality investigations and helping homeowners navigate remediation before concluding that the best solution was simply building healthier homes from the start. Today Dylan combines his construction background, environmental consulting experience, and certification as a Building Biology New Build Consultant through the Building Biology Institute to build homes designed to support the health of the people living inside them.

Episode 44: The Science behind Vapor Barriers, Wallpaper, Paint, and Spray Foam with Emily Mottram of Mottam and Maines

Send us a text with your questions, thoughts, and/or a love note regarding the podcast episode to help us know what to create more of! [https://www.buzzsprout.com/2470783/fan_mail/new] What does it actually mean to build a pretty good house, and why is that sometimes a better goal than building a perfect one? In this episode, Ashley sits down with Emily Mottram, licensed architect, building science educator, co-author of the Pretty Good House book, and one of the most thoughtful voices in the residential design space. Emily grew up on a dairy farm in Pennsylvania, got into architecture because her drafting teacher told her it was hard, and has spent the last two decades chasing every building science certification she could find, not because she thinks she knows everything, but precisely because she knows she does not. Together they cover an enormous amount of ground: what makes a house healthy when the answer is different for every person and every climate, why spray foam keeps showing up as a band-aid for design problems, what paint is actually doing to your walls and to the ocean, and why the building code is a recipe book that people keep making worse by swapping the wrong ingredients. Emily also shares the story of two back-to-back clients, one with multiple chemical sensitivities and one with a serious mold history, whose needs were almost perfectly opposite, and what that taught her about materials, assumptions, and listening. This is also a conversation about slowness, about pausing before adding more, doing better things instead of doing things better, and why the most important question to ask before reaching for any building product is whether you actually need it at all. If you are designing, building, or renovating and want to think more clearly about what you are putting into your home and why, this episode is required listening.

Episode 43: Mold Illness, Healthy Construction, and Healing with Brent Little of Pinehaven Healthy Homes

Send us a text with your questions, thoughts, and/or a love note regarding the podcast episode to help us know what to create more of! [https://www.buzzsprout.com/2470783/fan_mail/new] What happens when the person who builds healthy homes for a living becomes the one who desperately needs one? In this episode, Ashley sits down with Brent Little, a thirty-year construction veteran and founder of Pinehaven Healthy Homes in McCall, Idaho, for one of the most honest and human conversations this podcast has ever had. Brent was a high-capacity, driven builder who had been exposed to mold on job sites for decades without incident, until a brand new RV became the straw that broke the camel's back, and both he and his wife found themselves navigating one of the most isolating and misunderstood illnesses of our time. Brent walks through the full arc of what happened, from the early neurological symptoms he thought might be brain cancer, to the emotional dysregulation that had them considering psychiatric intervention for his wife, to the long and expensive road through functional medicine that led nowhere until he found Dr. Eric Dorninger and Lauren Lowenstein of the Biotoxin Lady community. He also talks candidly about what it is like to be a man going through chronic illness in an industry built on toughness, how CIRS has shifted his entire business model toward natural and low-toxicity materials, and why he now sees this experience as something that was given to him rather than something that happened to him. This episode is for anyone who has ever felt like they were doing everything right and still got knocked flat. It is also for every builder, tradesperson, and contractor who has never connected the dots between the materials they work with every day and the way their body feels. Brent's story is a reminder that the healthy home conversation belongs to everyone, not just the people building from scratch. THINGS MENTIONED IN THIS EPISODE: * CIRS cluster symptoms and VCS test [https://boards.com/a/zIJLT.iMxnzB] * HLA haplotype testing [https://www.testing.com/tests/hla-testing/] * Lauren Lowenstein, The Biotoxin Lady and her private CIRS community: thebiotoxinlady.com [http://thebiotoxinlady.com/] * Cholestyramine and Welchol binder protocol [https://www.survivingmold.com/docs/12_STEP_SHOEMAKER_PROTOCOL_FOR_CIRS.PDF] * Silicosis and respiratory health risks in the trades [https://pmc.ncbi.nlm.nih.gov/articles/PMC5971761/] CONNECT WITH ASHLEY Instagram [https://www.instagram.com/awakeningspaces/?hl=en] | Tiktok [https://www.tiktok.com/@awakeningspaces?lang=en] | Youtube [https://www.youtube.com/@awakeningspaces] | Website [https://awakeningspaces.com/] Ashley helps you renovate and build healthier homes to prevent future health issues from arising from your environment.

He has been in the trades since he was 18, studied Construction Management at Ohio State University, and has spent his career building in one of the most demanding environments in the country, a mountain ski town with high snow loads and complex site conditions that require serious technical skill to navigate. Two years ago, everything changed. Brent was hit with environmental illness that put him out of commission for over a year. The experience cracked open a whole new understanding of how the homes we build directly affect the health of the people living inside them, and it redirected his passion and his practice toward healthy building. Today Brent brings that hard-won personal experience together with decades of technical expertise to build homes that are as healthy as they are beautiful. Outside of work, he loves the outdoors, was a sponsored backcountry snowmobiler, and is in the process of adopting his eight-year-old son alongside his wife.

Episode 42: Passive House, Healthy Materials, and the Hierarchy of Healthy Building with Trey Farmer of Forge Craft Architecture

Send us a text with your questions, thoughts, and/or a love note regarding the podcast episode to help us know what to create more of! [https://www.buzzsprout.com/2470783/fan_mail/new] What does it actually mean to build a healthy home, and where do you start when everything feels equally important? In this episode, Ashley sits down with Trey Farmer, Austin-based architect, passive house advocate, and co-organizer of the Humid Climate Conference, for one of the most grounded and practically useful conversations this podcast has had on the intersection of building performance and human health. Trey brings a rare combination of credentials: passive house certification work, affordable housing and emerging tech projects, natural building experience, and a seat on the advisory board of Malachi's Message, a Texas-based mold awareness nonprofit. He is also just deeply fun to talk to. Together they unpack what passive house certification actually is, why it functions as such a reliable litmus test for the whole project team, and what it means in practice to build a home that controls its air, vapor, and thermal layers before worrying about anything else. Trey shares his hierarchy of healthy building priorities, from water control and airtightness all the way through materials and filtration, and why that sequence matters so much for homeowners trying to figure out where to put their limited time and budget. They also get into the gas versus induction debate, EMF considerations in context, the growing availability of red list free and declare-labeled materials, and why building smaller and better is often the most powerful financial decision a homeowner can make. This one ends with both Ashley and Trey agreeing that the healthy home space is only as strong as its community, and if you have been looking for your people, this episode will feel like coming home.

Episode 41: Understanding CIRS, Biotoxin Illness, and the Healthiest Home in America with Dr. Eric Dorninger

Send us a text with your questions, thoughts, and/or a love note regarding the podcast episode to help us know what to create more of! [https://www.buzzsprout.com/2470783/fan_mail/new] What if the chronic illness your doctors keep missing has been living in your walls the whole time? In this episode, Ashley sits down with Dr. Eric Dorninger, naturopathic doctor, acupuncturist, and CIRS specialist at Roots and Branches in Boulder, Colorado, who has spent over two decades helping patients with complex, mystery illnesses find the underlying causes that conventional medicine keeps overlooking. Dr. D brings something rare to this conversation: he is not just a clinician who treats CIRS. He is a patient who nearly lost everything to it, and his family's six-month remediation, biblical living conditions and all, is one of the most grounding and honest accounts of what this illness actually costs. Together Ashley and Dr. D walk through the full arc of what CIRS is, how it is properly diagnosed using validated biomarkers rather than urinary mycotoxin tests, what the Shoemaker Protocol actually involves and why so many people think they have done it without ever truly doing it, and why clean building plus proper binder is still the irreplaceable one-two punch that nothing else replaces. They also get into the naturopathic therapeutic order, why effort does not equal outcome in chronic illness, and the real cost of CIRS in America when you follow the dollars all the way to memory care. Dr. D also shares what he is building right now, quite literally, the healthiest home in America, a stick frame build redesigned from the ground up with CIRS patients in mind, and what he has learned the hard way about construction loans, lumber quality, builder integrity, and why having an owner's rep on your project is not optional when your health is on the line. If you are navigating chronic illness, trying to understand CIRS, or building a home for a sensitive body, this episode is essential listening.
