Wellness Architecture

Wellness architecture is the design of buildings and landscapes whose main job is to support physical, mental and emotional wellbeing in everyday life, outside the hospital. It covers spas and thermal baths, retreats, wellness hotels, yoga and fitness spaces, and the ordinary offices and homes now planned against health standards such as WELL and Fitwel. Its tools are the basic conditions of a room: daylight, air, water, sound, materials and contact with nature.

What is wellness architecture?

The field starts from a broad idea of health. Instead of treating a disease, a wellness building tries to keep people well: rested, calm, active and connected to others and to the place they are in. The founding text most often cited for that idea is the constitution of the World Health Organization.

"Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."

World Health Organization, Constitution (adopted 1946)

Read that way, almost any building can be designed for wellbeing, and the term now spans three scales. The first is the dedicated wellness destination: the bathhouse, the sauna, the retreat in the forest, the ayurveda centre, the health resort. The second is the everyday building rated for its effect on occupants, where certification systems score air, light, water and movement in offices and housing. The third is the single room or object designed for rest, such as a nap pod in a workplace.

It helps to say what the field is not. Hospitals and clinics, where the brief is diagnosis and treatment, belong to healthcare building design, even though they borrow many of the same ideas. Homes and neighbourhoods for later life are covered under ageing well design. Rooms made purely for prayer or silence are their own type, and the theory of why people respond to living systems is the subject of biophilic architecture. Wellness architecture draws on all of these, but its client is usually a healthy person who has chosen to spend time somewhere restorative.

A short history of wellness architecture

Bathing is the oldest thread. Roman thermae led bathers through a sequence of warm, hot and cold rooms, and the large public baths also held exercise courts and places to meet and read. Hot springs drew towns around them for the same reason. At Bath in England, the Great Bath of the Roman town, fed by a natural hot spring, can still be seen today.

The nineteenth century added the spa town and the sanatorium, and early modernism turned their faith in sun and fresh air into a design method. Alvar and Aino Aalto's Paimio Sanatorium in Finland, completed in 1933 for tuberculosis patients, treated light, colour, acoustics, ventilation and views of nature as part of the treatment. Its sun balconies and terraces are well known, and so are smaller details, such as washbasins shaped to run quietly and lamps placed out of the line of sight of a patient lying in bed.

Evidence followed intuition. In 1984 the journal Science published Roger Ulrich's study of surgical patients in a Pennsylvania hospital: those whose windows looked onto a natural scene had shorter stays and took fewer strong painkillers than matched patients facing a brick wall. The study was about a hospital, but it became the reference point for designers arguing that a view is not a luxury.

In 1996 Peter Zumthor completed the thermal baths at Vals in Switzerland, built over the only thermal springs in the canton of Graubünden. Clad in locally quarried Valser quartzite and conceived as a kind of stone quarry, it alternates small, intimate rooms with a large meandering bath, and it is still the building most designers have in mind when they draw a spa. The most recent turn is measurement. The WELL Building Standard, launched in 2014, made wellbeing a certifiable property of ordinary buildings.

Key principles of wellness architecture

Wellness buildings vary from a nap pod to a resort, but the strongest ones share a small set of moves. Each principle below is illustrated with work by uni.xyz members.

Slow thresholds

Arrival sets the mood. A long approach, a change of floor material, a darker corridor before a bright pool: these give the body time to switch pace. FILTER, by Şevval Neva Durmuş, Zeynep Yıldırım and Nehir reyhan Boyacı, which received a People's Choice Award in the UHealth competition, makes this the whole concept.

"...the design introduces a filtered and gradual spatial experience that gently guides the user into the space."

Water, heat and the bathing sequence

Spas still follow the Roman logic of contrast: warm, hot, cold, rest. The design question is how to make each step feel different through light, temperature, sound and touch, not just through signage. Hjerta, an Editor's Choice in the Thermal Blue competition by Nadia Cheng and Enoch Liu, works this out in section.

Daylight and fresh air

Daylight sets the body clock and fresh air keeps rooms healthy, so wellness buildings tend to be shallow in plan, open in section and naturally ventilated wherever the climate allows. Both appear as requirements in the WELL standard, but the architectural answer is old: courtyards, roof lights, perforated screens and deep overhangs. The Community Therapy Center by Sylwia Sek, a winning entry in the Restore competition, is a clear member example.

Quiet, sound and rest

Noise is one of the commonest complaints in any building, and sleep is one of the cheapest forms of recovery. Slumber by Yingyu1 Lam, a winning entry in the Slumber competition, designs a mobile Snail Pod for workplaces that offers a short nap of 10 to 15 minutes, with temperature, lighting, materials and sound all considered. SNOOZE, by Supriya sinha, Reesha Haya, Mukesh Jangid and Devashish Solanki, scales the same idea up into a whole rest building.

Nature in view and within reach

The view out, planting inside and a path that leads into the landscape are the most direct ways a building can borrow the restorative effect of nature. The theory is set out under biophilic architecture; in wellness projects it usually turns into a simple rule that the resting spaces get the best views. SIBON by Wojciech Nowak, a winning entry in the Cast Away 2.0 competition, starts from the idea that wellness rests on balance and harmony across all its aspects.

Local materials and touch

People in a spa are barefoot and lightly dressed, so materials are felt as much as seen. Stone, timber, earth and lime suit that close contact and tie the building to its place. Our editorial on STAPATI's Nirava Ayurveda Holistic Centre in Alappuzha describes laterite stone, timber, woven cane and louvered shutters set inside a curving concrete frame, with slender vertical fins that modulate daylight across the therapy suites.

Thermal baths are the most visible theme in this topic, largely because of the Thermal Blue competition, whose entries here set their bathhouses in Iceland. The entries below show how differently members read the same brief.

THERMAL BLUE by Daniela Georgieva, subtitled "Spa by the Nature", is the most liked project in this topic. As our editorial review describes it, the plan begins with two overlapping circles of trail that gather a river, a hiking route and a bus stop; the spa and hotel sit on their overlap, half buried in grass, with small guest houses on the outer arcs.

Architecture as the Bridge to Nature by Daria Semenova and Ho Nam Wong, an Editor's Choice in the same competition, makes the bathhouse something you can walk over. The editorial notes that the boards place it near Hveragerdi at the start of a trekking trail, with a green roof paved in local soil and vegetation and pools sitting in a hollow formed by a curving wall.

Waterway by Archi Cat, also an Editor's Choice at Thermal Blue, draws an artificial stream that flows visually into the river, with buildings shaped like icebergs or volcanic craters spread along it to hold a main pool, massage rooms and a sauna. Its renderings show bathers in round pools between curved concrete walls.

Away from Iceland, retreats and everyday rest take over. CAST AWAY by IPEK OZER and Aylin Erdogan, an Editor's Choice in the Cast Away 2.0 competition, designs a place of total serenity where people can step away from daily responsibilities, alone or with friends. Community Therapy Center by Sylwia Sek sets out to be a space where everyone can feel safe and supported, and to encourage people to seek help and share experiences, which brings mental health into the brief as directly as any spa brings in water.

The journals add built work from around the world. Our article on the Joyous Spring Wellness Center by Soong Lab+ in Beijing describes a disused swimming facility reopened in 2024, where removing the glass roof over the central pool turned a dark underground space into a sunlit sunken courtyard. Others cover CYCL, a 163 square metre sauna and bath house by YŪ Momoeda Architects in Yamanakako, inside the Fuji-Hakone-Izu National Park, and the Eutierria Wellness Centre by Urban Circle in Karjat, which the editorial describes as weaving through the existing forest canopy without cutting down a single tree.

Challenges and future directions

The first challenge is credibility. Our STAPATI editorial opens by saying that wellness architecture has a credibility problem, and the criticism is fair: a lot of work labelled wellness is a spa hotel with soft lighting and natural-looking finishes. The test is whether the building actually changes conditions for the people inside it: better light, cleaner air, real quiet, real contact with the outdoors.

The second is evidence. Certification has made wellbeing measurable, but measurement is not the same as outcome. Studies summarised on the WELL Building Standard page report mixed results when certified and uncertified offices are compared, with higher satisfaction on some measures and none on others. Designers should treat a rating as a checklist of good conditions, not as proof that a building heals.

The third is resources. Pools, saunas and heated water use a lot of energy and water, and the most remote retreats depend on long journeys. DISEMBARKED by Colton Newbury, a winning entry in the Green Retreat competition set in Fairbanks, Alaska, answers this on its own boards by drawing hot springs into drinking water, thermal baths and hydroponic growing.

The fourth is access. Hjerta's authors note that bathing has a history of privacy and privilege, and they argue for the bath as a luxury for all. Public baths, workplace rest rooms and community therapy spaces may do more for public health than another exclusive resort. Adaptive reuse, as at Joyous Spring, is a promising route, because it brings wellness programmes into existing urban buildings.

Wellness architecture for students and designers

Wellness briefs reward careful sectional thinking, because light, heat, water and sound all travel vertically. Good thesis angles include a public bathhouse for a dense neighbourhood, a rest building for shift workers, a reuse of an empty pool or industrial shed, or a retreat that limits its own footprint. Paudwar Tatopani by Subhan Karki, entered in UnIATA '26, is a strong precedent: it reimagines Nepal's geothermal hot springs as a wellness destination rooted in Himalayan vernacular traditions, with responsible water management, seismic resilience and a capped visitor number to protect the springs.

Frequently asked questions

What is wellness architecture?

Wellness architecture is the design of buildings and landscapes that support physical, mental and emotional wellbeing for healthy people, outside the hospital. It includes spas, thermal baths, retreats and wellness hotels, and also everyday buildings designed for better light, air, sound and contact with nature.

What is the WELL Building Standard?

WELL is a rating system launched in 2014 that certifies buildings on their effect on occupant health. Its concepts cover air, water, nourishment, light, movement, thermal comfort, sound, materials, mind and community, and certified projects must pass preconditions and earn optimisation points.

How is Fitwel different from WELL?

Fitwel is another health certification, operated by Active Design Advisors, whose service marks are owned by the US Department of Health and Human Services. It describes itself as suited to existing properties as well as those in design, with no prerequisites, while WELL is built around mandatory preconditions.

What makes a good spa or thermal bath design?

A clear sequence of warm, hot, cold and rest; slow thresholds between them; materials that feel good under bare feet; controlled light and quiet; and views or routes out into the landscape. Zumthor's baths at Vals remain the standard reference for how stone, water and light can do this together.

Can architecture improve mental health?

Buildings cannot replace care, but they can reduce stress and support recovery. Ulrich's 1984 study linked a window view of nature with shorter hospital stays, and daylight, quiet, privacy and places to meet others are now standard goals in wellness and therapy buildings.
