If we accept the premise that buildings are not neutral — that they influence how we think, feel, recover, focus, and connect — then architecture is no longer just a technical or aesthetic discipline. It becomes a physiological one.

We are, as William R. Ott observed, “basically an indoor species.” In modern society, time spent outdoors is often so negligible it barely registers in daily life. Current estimates suggest we spend around 90% of our lives indoors, moving between buildings and vehicles that mediate our exposure to light, air, sound, materials, temperature, and social interaction.

If this is true — and the evidence is clear that it is — then the spaces we design are not passive containers for life. They are active participants in human health.

From Shelter to System

Historically, architecture’s primary obligation was shelter: protection from climate, threat, and scarcity. Over time, shelter became infrastructure, infrastructure became real estate, and real estate became an asset class. Somewhere along the way, human wellbeing became secondary to efficiency, yield, speed, and image.

Yet our bodies never adapted to this shift.

Environmental psychology, neuroscience, and building science now show that prolonged exposure to poorly designed environments can contribute to chronic stress, sleep disruption, cognitive fatigue, anxiety, and depressive symptoms. Inadequate daylight, stale air, noise pollution, toxic materials, thermal discomfort, and lack of connection to nature all register — not consciously at first, but biologically.

The built environment, in other words, can quietly dysregulate us.

Conversely, access to daylight, views, fresh air, natural materials, acoustic refuge, legibility of space, and meaningful connection to nature has been shown to support recovery, focus, emotional regulation, and overall wellbeing. This is not ideology; it is measurable physiology.

Wellness Is No Longer a Niche

The market has noticed.

According to Technavio, the global wellness real estate market is forecast to grow by USD 768.6 billion between 2024 and 2029, at a compound annual growth rate of over 20%. Demand is being driven largely by the luxury residential and hospitality sectors, where affluent buyers are seeking environments that actively support physical and mental health.

The language has shifted too. Briefs increasingly reference regenerative living, holistic amenities, biophilic design, and mental wellbeing. Wellness spaces — once peripheral — are now central: thermal suites in hotels, meditation rooms in workplaces, recovery spaces in healthcare, quiet rooms in schools and airports.

On paper, this looks like progress.

In practice, it often reveals a problem.

The Knowledge Gap

While ambition has grown, capability has not always kept pace.

Designers are now expected to integrate principles drawn from diverse and often siloed disciplines: building biology, neuroscience, environmental psychology, biophilic design, eastern spatial philosophies such as Feng Shui, Vastu and Kanso, Nordic concepts like Hygge, and — in Australia — deep relationships to Country, memory, and narrative.

Much of this knowledge is credible. Some of it is misunderstood. Some is poorly evidenced. Much of it is difficult to translate into buildable, compliant, and contextually appropriate design decisions — particularly under commercial pressure.

The result is a fragmented approach: wellness as an overlay rather than a framework; features rather than systems; intention without integration.

This is where many practitioners feel uneasy. We sense that design can do better — but we are rarely given the time, tools, or consolidated knowledge to interrogate our decisions properly.

Design as Responsibility

If architecture has the capacity to harm or heal, then the question becomes ethical as much as professional.

What does it mean to specify materials without understanding their impact on indoor air quality?
To prioritise visual drama over acoustic comfort?
To design spaces that photograph well but exhaust the nervous system?

When the consequences of these choices are delayed, invisible, or diffuse, accountability becomes easy to avoid. But avoidance does not negate impact.

Wellbeing-focused design is not about perfection, nor about adopting every trend that passes through the wellness industry. It is about literacy: understanding how space affects the human body and mind, and making informed, proportionate decisions as a result.

Toward an Architecture of Wellbeing

An architecture of wellbeing is not a style. It is a way of thinking.

It asks different questions:

• How does this space feel to inhabit over time, not just at handover?
• What does it demand of the nervous system?
• Who is excluded, overstimulated, or overlooked?
• What does it return to people, beyond function and image?

It recognises that healing does not come from a single intervention, but from coherence: light, air, materiality, sound, layout, access to nature, cultural meaning, and psychological safety working together.

This is not about designing sanctuaries everywhere. It is about designing with care, grounded in evidence and humility
