I'd forgotten what it felt like to be outside
At King's College Hospital in London, the boundary between critical care and the living world has been quietly redrawn. A rooftop garden — equipped with oxygen lines, electrical outlets, and beds of jasmine and lavender — now offers the hospital's most vulnerable patients something medicine alone cannot prescribe: the sensation of open sky. In opening this space, clinicians are asking an old question with new urgency: whether healing the body can be hastened by remembering, even briefly, what it means to be alive outside.
- Critically ill patients, many of whom spend weeks or months confined to sterile indoor rooms, face a psychological erosion that standard intensive care was never designed to address.
- A 29-year-old woman awaiting heart surgery wept the moment she felt sunlight for the first time in two months — still tethered to life support, but suddenly reconnected to the world.
- King's College Hospital has responded by opening a £2.7 million rooftop ICU garden, the first of its kind in the UK, capable of hosting six critically ill patients simultaneously amid fragrant plantings and open air.
- Doctors will now track heart rate, breathing, and pain levels to determine whether nature exposure measurably accelerates recovery for the sickest patients.
- If the data confirms what clinicians and designers believe, the model could be replicated across the National Health Service — reshaping how the UK thinks about critical care environments.
When Hollie Allan stepped off the hospital elevator onto the roof of King's College Hospital, she had not been outside in two months. She was still connected to feeding tubes and life support equipment, but the doors opened, the cold air met her face, and she began to cry. "I'd forgotten what it felt like to be outside," she said.
Allan, 29 and awaiting critical heart surgery, became the first patient to use the UK's first rooftop intensive care unit — a garden space designed for the hospital's sickest patients. Perched above a 60-bed ICU ward, the space can accommodate six critically ill patients at once, each bed positioned near weatherproof boxes housing oxygen connections and electrical outlets. Landscape architects Sarah Price and the late Nigel Dunnett — who had previously collaborated on London's Olympic Park — designed the plantings: honeysuckle, jasmine, and lavender chosen for their fragrance, alongside grasses and foliage patients can touch from their beds. The project cost more than £2.7 million, funded through the hospital's charitable foundation.
Research has long linked natural light and outdoor environments to shorter hospital stays and improved wellbeing, but those benefits have almost never reached patients in critical condition. The team at King's College intends to change that calculus, monitoring heart rate, breathing, and pain levels to measure whether the garden genuinely accelerates recovery. Dr. Phil Hopkins, an intensive care specialist, framed the ambition plainly: "We don't just want to save lives. We want to return them to their lives as soon as possible."
Allan spent hours in the garden, even through electrical storms. The rooftop will also be open to ICU staff during breaks, acknowledging that the psychological weight of intensive care extends to those who deliver it. Hospital leadership hopes the model will eventually spread across the National Health Service — but for now, it stands alone: a place where the most fragile patients in one of London's busiest hospitals can feel, once more, the simple fact of open air.
Hollie Allan stepped out of the hospital elevator onto the roof of King's College Hospital in south London, and for the first time in two months, she felt sunlight on her face. She was still tethered to her bed, still connected to feeding tubes and life support equipment, but the nurses around her had warned her about one thing: prepare for the cold. When the doors opened, she began to cry.
"It's so nice," she said, wiping her eyes. "It's so beautiful. I'd forgotten what it felt like to be outside."
Allan, 29 years old and waiting for critical heart surgery, became the first patient to experience the UK's first rooftop intensive care unit—a garden space designed specifically for the sickest patients in the hospital. The space sits atop one of the country's largest ICU wards, a 60-bed unit at King's College. It can accommodate six critically ill patients at once, each bed positioned near weatherproof boxes containing electrical outlets and oxygen connections. Some sections are shaded by canvas awnings. The rest opens directly to sky and air.
The garden itself is the work of two designers: Sarah Price, a landscape architect, and Nigel Dunnett, a landscape architect who collaborated with Price on the Olympic Park for the 2012 London Games. Dunnett died before the rooftop garden was completed. The beds are planted with honeysuckle, jasmine, and lavender—flowers chosen for their fragrance—alongside grasses and foliage of varying textures that patients can touch and smell from their beds. The entire project cost more than £2.7 million, funded through the hospital's charitable foundation.
Research has long suggested that exposure to natural light and outdoor environments improves patient wellbeing and shortens hospital stays. But those benefits have rarely been available to people in critical condition, whose medical needs have confined them to sterile indoor rooms. The doctors at King's College are now planning to measure whether this changes that equation. They will monitor heart rate, breathing rate, and pain levels to determine whether time in the rooftop garden actually accelerates recovery.
Dr. Phil Hopkins, a specialist in intensive care at King's College, describes the project as more than a medical intervention. "We don't just want to save lives," he said. "We want to return them to their lives as soon as possible." For patients who have been, in his words, "torn from their reality" and institutionalized in a hospital, the simple sensation of wind and weather can help them begin to reorient themselves to the world outside. Allan spent hours at a time in the garden, even during electrical storms. "It's a wonder," she said.
The rooftop space will also be available to ICU staff during their breaks—a recognition that the psychological toll of intensive care work extends beyond the patients themselves. Clive Kay, the hospital's chief executive, expressed optimism that the model could extend far beyond King's College. If the data supports what the designers and doctors believe, he suggested, the rooftop garden could become a template for intensive care units across the National Health Service. For now, though, it remains singular: a place where the most fragile patients in one of London's busiest hospitals can feel, once again, what it means to breathe open air.

We don't just want to save lives. We want to return them to their lives as soon as possible.— Dr. Phil Hopkins, intensive care specialist at King's College Hospital
It's the antithesis of a hospital room.— Sarah Price, landscape architect who designed the garden
The Hearth Conversation Another angle on the story
Why does a rooftop garden matter so much for people who are already receiving world-class medical care?
Because being in an ICU for months doesn't just affect your body—it erases your sense of being alive. You're in a controlled room, fluorescent lights, machines beeping. Your mind starts to give up even if your body is healing.
But these patients are still on life support. How is that safe?
The infrastructure travels with them. Oxygen lines, electrical connections—it's all built into weatherproof boxes beside each bed. They're not disconnected from care; they're just receiving it in a different place.
What did Hollie Allan's reaction tell you about what was missing?
She cried. She'd forgotten what outside felt like. That's not a small thing. For someone who's been fighting for survival in a box for two months, remembering that the world exists outside that box might be the thing that lets them actually want to survive.
The hospital is measuring heart rate and breathing. What are they really looking for?
Proof that nature isn't just nice—that it actually heals. If the data shows shorter stays and better vital signs, this becomes replicable. It stops being a luxury and becomes standard care.
Why did Nigel Dunnett's death matter enough to mention?
Because he designed this but never saw it finished. There's something poignant about that—a landscape architect creating a space for healing that he himself never got to witness working.
