I'm Ryan Mair, founder of Xpanded Concepts. I'm a qualified Building Biologist | QBCC Licensed Builder | Building & Pest Inspector.
This unique combination of skillsets allows me to assess homes through a far more holistic lens than traditional building or environmental assessments alone. By combining building science with health-focused environmental assessment, I'm able to identify, assess, and help address underlying environmental concerns in a practical and evidence-informed way.
My approach is centred around bridging the gap between building science and wellness, helping uncover how the built environment may be influencing occupant health, while also taking a more proactive approach through healthier home selection, environmental optimisation, and guidance around building practices, products, and lifestyle habits that may help support healthier living environments.
I understand that many practitioners work with clients who are searching for answers, dealing with complex or chronic health concerns, or simply trying to create healthier environments for themselves and their families. My role is not to diagnose health conditions, but to help investigate and better understand the built environment those clients are living in every day.
I genuinely value working alongside allied and integrative health practitioners who recognise the importance of healthy indoor environments and who want trusted, practical support for clients where environmental factors may be worth considering. Whether the goal is investigation, education, prevention, or simply helping clients feel more confident in their home environment, my aim is always to provide grounded, practical, and easy-to-understand guidance that helps support the bigger picture of health and wellbeing.
For clients where you suspect the home environment may be the problem. Investigative services are heavily focused around
For clients looking to create healthier living environments to facilitate recovery or to simply optimise their health & wellbeing. We provide various services to optimise the environment.
Xpanded Concepts is based on the Sunshine Coast, with local technician-based services available throughout the
Many services are also available Australia-wide through guided remote testing and consultation. While remote services naturally have some limitations compared to being physically on-site, they allow clients in locations without access to a Building Biologist or environmental investigator to still access professional guidance and testing support.
This process typically involves equipment or sampling kits being sent directly to the client, along with online guidance on testing methodology, sample collection, and environmental assessment procedures. Results are then professionally analysed and interpreted, with practical recommendations and follow-up support provided where required
My approach to environmental health is grounded in practicality, education, the precautionary principle, and reducing overall environmental stressors where reasonably achievable. My work is centred around helping clients better understand the environments they live in and identifying practical opportunities for improvement. My assessments and consultations are guided by core building biology principles, looking at the home as an interconnected environment & my approach is also grounded in the precautionary principle.
My overall philosophy is heavily focused on harm reduction and practical intervention. Not every exposure can be completely eliminated, and attempting to create a "perfect" environment is often unrealistic. Instead, the goal is to identify the most meaningful and achievable opportunities for improvement based on the client's circumstances, goals, and priorities. Where appropriate, recommendations are guided by the hierarchy of control, prioritising practical source reduction, environmental improvements, and behavioural strategies before relying on more reactive or temporary measures.
When you suspect the home or work environment may be the cause of your client's symptoms, hindering their recovery, or increasing their toxic load, I'm the person you send in.
Using a combination of Building Biology principles, specialist equipment, and laboratory testing and analysis, I determine whether environmental contamination or exposure is present, identify the source where possible, or rule it out where it isn't.
In my experience, sometimes the home environment is the root cause of the problem. Other times the conditions within the home are simply hindering recovery. Either way, identifying and addressing the issue is essential to your client moving forward.
Before setting foot in the home I take time to understand your client's symptoms, the conditions and history of the property, and any specific concerns. From there I develop a targeted testing strategy rather than a one size fits all approach.
The home is assessed based on the agreed strategy. Where indicated, laboratory testing is conducted for specific environmental contaminants, giving you definitive results rather than assumptions.
Your client receives a clear report of findings with prioritised, actionable steps to improve conditions in the home. Plain language, no overwhelm.

Building Biology Investigations combine my experience as a Building Biologist, Builder, and Building Inspector to assess both the occupants and the home through a healthy home lens.
Unlike investigations that focus solely on testing or the building itself, this approach considers the relationship between the people living within the home, the building, and the environmental conditions present. Drawing on my building background, I assess the home for defects, moisture issues, ventilation concerns, building performance problems, and other conditions that may be contributing to an unhealthy indoor environment. Through a Building Biology lens, I also consider factors such as mould and moisture, indoor air quality, chemical exposures, EMFs, water quality, lighting, and other environmental influences.
The objective is to identify potential environmental stressors, provide clarity around possible contributing factors, and determine the most appropriate next steps for further investigation, testing, remediation, or healthy home improvements where required.
My approach to mould investigations is almost always testing-first focused. I regularly encounter homes with significant mould contamination despite little to no visible signs being present.
Because of this, laboratory-based analysis often plays a central role in helping guide both the investigation process and the recommendations that follow.
Testing is not simply used to confirm whether mould is present, but to help better understand the environmental conditions within the home, identify potential patterns, and guide the next steps of the investigation.
For local on-site investigations, assessments may include:
A major focus is identifying potential moisture sources and understanding why mould growth or microbial amplification may be occurring within the building environment.
For remote testing my process is;
The limitations compared to being physically on site is around my ability to try and identify the moisture source. However laboratory analysis can still provide valuable information that helps guide recommendations, identify potential patterns of concern, and assist clients in understanding where further investigation may be required.
My approach to EMF assessments is grounded in measurement, practicality, education, and exposure reduction where reasonably achievable. I take a testing-led approach focused on identifying the most significant sources of exposure within the home environment. Complete elimination of EMF exposure is often unrealistic in modern environments, so the primary goal is generally to reduce unnecessary exposure where practical and appropriate. Particular attention is placed on areas where occupants spend the most time, such as bedrooms, home offices, and primary living spaces.
My approach to lead investigations is always testing-first focused. Where lead contamination is suspected, particularly in environments involving children, renovations, deteriorating paint, or older building materials, laboratory-based testing is used to help determine whether contamination is present and to better understand the level and potential extent of concern.
The goal is to move beyond assumptions and provide evidence-based information that can help guide safer decision-making and practical next steps.
My approach to methamphetamine contamination investigations is based on established sampling methodology and laboratory-based analysis.
Testing is conducted using the NIOSH 9111 sampling method to help determine the presence and level of methamphetamine contamination within the property environment. Laboratory analysis is then used to provide measurable results that can help guide decision-making around further investigation, cleaning, remediation, or occupancy considerations.
"No paperwork, no formal process. If you have a patient whose home environment may be worth investigating - I'm one call away."
If you're confident a home assessment would help, pass on your client's details and I'll reach out within one business day.
I'll introduce myself, explain the process, and take it from there. I'll be in touch if a case discussion would be useful.
Not sure if a home assessment is the right fit? I'm genuinely happy to talk through your client's situation before any referral is made.
"No commitment, no obligation, just a practical conversation between professionals.
Presented with: Sleep disturbance, behavioural issues, and neurological symptoms that noticeably improved when away from the home.
Referred by: Allied health practitioner who suspected the home environment may be a contributing factor.
Based on the age of the property, its location, and the client's presentation, my preliminary assessment pointed toward heavy metal contamination, specifically lead as a priority concern.
On assessment, significant lead contamination was identified in the external ground surrounding the home. Deteriorating lead paint on both the property and a neighbouring home had been shedding into the soil where the children regularly played. While internal levels were comparatively minor, the pattern of contamination strongly suggested the external environment was being tracked into the home.
This was not something the family had any reason to suspect, nor something they could have identified without specialist investigation.
What happened next: The family received a detailed report of findings along with prioritised recommendations to protect the children and prevent further transfer of contamination from outside into the home. Longer term remediation options were also outlined.
The takeaway for practitioners: The referring practitioner's instinct that the home was worth investigating proved correct. A child presenting with neurological symptoms that improve away from the home is a clinical signal worth acting on, and in this case, the home environment was hiding a significant and addressable source of exposure.
Presented with: Chronic Inflammatory Response Syndrome (CIRS) with suspected mould contamination in the home. No known water damage history, though a persistent musty odour was present downstairs.
Referred by: Allied health practitioner managing the client's CIRS presentation.
Given the severity of the client's condition, mould contamination was the primary concern going in. Despite no obvious history of water damage, a thorough assessment revealed three separate contamination sources, two of which were completely hidden.
A rising damp issue in a downstairs wall was identified as a likely primary source of the contamination presenting on the lower level. Upstairs, a leak in the ensuite bathroom had gone undetected, heavily contaminating the adjacent walk-in wardrobe and cross-contaminating the master bedroom, meaning the client was storing and wearing clothes that were potentially carrying mould spores with her throughout the day.
Perhaps most unexpectedly, external air sampling in the backyard returned excessively high mould counts, exposing the client to significant contamination even in her own outdoor space, an area she had no reason to suspect.
What happened next: The findings required meaningful building remediation, not a surface clean. The bathroom leak needed to be properly repaired, the contaminated walls stripped back rather than treated on the surface, waterproofing installed, and drainage improved to address the rising damp at its source.
This distinction matters. Cleaning visible mould without addressing the underlying building issue guarantees it returns. With 28 years in the building industry, I was able to not only identify the contamination but provide clear, realistic guidance on what remediation actually needed to look like, and why shortcuts wouldn't work.
The takeaway for practitioners: For a client managing CIRS, the home environment isn't just a background concern, it can be actively undermining every clinical intervention you make. In this case, three hidden contamination sources were identified that the client had no awareness of, including one outside the home entirely. A thorough investigation changed the entire picture.
I'm sure you see as much as I do the devastating effects a toxic environment can have on unsuspecting people. Many people simply don't know what they don't know about the home environment and the potential impact it can have on health & wellbeing. Often, issues are not visible, obvious, or even considered until problems have already developed.
A major focus of my work is therefore not just identifying existing concerns, but also helping clients create healthier living environments proactively. Reducing potential environmental stressors before they become larger problems.
These services may be particularly relevant for health-conscious individuals and families, clients experiencing chronic or unexplained health concerns, environmentally sensitive individuals, or simply people wanting to better understand and optimise the environment they spend most of their time in.
Importantly, this approach is not based on the assumption that the home is always the cause of a person's health concerns. Rather, it recognises that the built environment is one piece of the broader health puzzle, and in some cases may be a contributing factor worth considering.
One of the best places to start when creating a healthier home environment is choosing the right property in the first place.
As a QBCC Licensed Building & Pest Inspector, I provide pre-purchase building and pest inspections in accordance with the relevant Australian Standards. These inspections help identify major defects, safety concerns, maintenance issues, and visible timber pest activity within the property.
In addition to standard building and pest inspections, I also offer optional building biology and environmental assessment upgrades for clients wanting a broader understanding of the home environment from a health-focused perspective.
Depending on the client's concerns and goals, this may include environmental testing and assessments relating to factors such as mould and moisture, indoor air quality, EMF exposure, water quality, ventilation, and other building-related environmental considerations.
Whole Home Optimisation is a more proactive, health-focused service designed to help clients better understand and improve the overall living environment within their home.
This process takes a broad building biology approach, assessing multiple environmental factors that may influence comfort, wellbeing, recovery, sleep quality, and overall health outcomes within the built environment.
The goal is not perfection, but helping identify practical opportunities to create a healthier, lower-tox, and more supportive living environment based on the client's goals, concerns, priorities, and lifestyle.
Creating a healthier home is often far easier during the planning and construction stages than trying to correct problems later.
I offer building biology-informed support for clients during various stages of the building process, including:
The focus is on helping clients incorporate healthier building principles relating to ventilation, moisture management, material selection, lighting, EMF considerations, and overall environmental health within the built environment.
A major passion of mine is also helping people navigate the increasingly confusing world of "healthy home" products.
Social media and online marketing are now flooded with health and wellness products making bold claims, often with misleading marketing, poor-quality science, little real-world testing, or companies that have very limited understanding of the products they are selling.
The goal of the Healthy Home Product Hub is to help cut through that noise by researching, analysing, and educating around products that may genuinely provide value within the healthy home space.
This includes looking beyond marketing claims and exploring factors such as product design, practical performance, scientific evidence, safety considerations, real-world usability, and overall value, with the goal of helping people make more informed decisions about the products they bring into their homes.
