Hospital roof garden lets critical care patients spend hours outdoors with full medical care

On a south London hospital rooftop, seriously ill patients are being wheeled outside for hours of fresh air, sunlight, and views—without losing any of the medical support they need. The innovative space at King’s College Hospital lets intensive care patients and their families step out of the ward and into a garden built specifically to deliver clinical care in an outdoor setting.

Staff call it a radical blend of medicine, design, and compassion: an accessible roof garden that supports full life-sustaining treatment while aiming to ease stress, lift mood, and speed recovery for people who often spend weeks or months inside critical care.

What the rooftop critical care garden actually is

Perched atop the hospital’s 60-bed critical care unit, the garden is equipped to accommodate up to six patients at a time while they remain connected to essential equipment. Rather than a symbolic courtyard, this is a functioning extension of the ICU where ventilators, monitors, and medical gases are available on site.

• Clinical capability: Patients retain access to full life support without being disconnected from machines or medical gases.
• Capacity: Space for up to six beds at once, designed for extended visits outdoors.
• Integration: Staff can continue routine critical-care interventions while the patient benefits from an outdoor environment.

How clinicians keep patients safe and connected outside

The team solved a practical problem: how to provide intensive-level care in an open-air setting. Engineers and clinical staff installed six weatherproof medical cabinets that supply power, data, and medical gas lines directly to each patient station. That infrastructure lets nurses and doctors monitor and treat patients exactly as they would inside the unit—only now the setting includes sky, plants, and sunlight.

• Weatherproof cabinets deliver electricity, oxygen and suction, and network connections.
• Design allows uninterrupted mechanical ventilation and continuous monitoring.
• Staff have protocols that mirror in-unit care, with added procedures for transfer and outdoor safety.

Design choices: plants selected to soothe and engage

The rooftop’s planting plan was intentional. The landscape team prioritized sensory appeal—fragrance, texture, and familiarity—to invite interaction rather than passive viewing. Aromatic herbs and native species were chosen for their calming and stimulating qualities.

• Fragrant herbs such as rosemary, sage, and oregano provide scent-based stimulation.
• Tactile plants like lamb’s ear encourage touch and engagement for patients and visitors.
• Native species were used to support a low-maintenance, resilient planting scheme.

The planting strategy was developed with input from acclaimed designers: landscape architect Nigel Dunnett, a professor at the University of Sheffield, and Sarah Price, a multi-time Chelsea Flower Show winner.

Voices from the roof: patients, clinicians, and charity leaders

Patients who spend time on the rooftop describe it as a return to normalcy and a morale booster. One patient waiting for a major heart operation told reporters she would sit outside “even in bad weather” because the outdoor time makes her feel more human.

Clinical leaders emphasize the holistic aim. Dr. Tom Best, the unit’s clinical director, has pointed to research showing that time in nature can influence recovery trajectories, and he frames the garden as part of treating the whole person—mind as well as body.

Representatives from the King’s College Hospital Charity framed the project as a blend of dignity, innovation, and empathy. The charity describes the rooftop as the UK’s first outdoor critical care garden and highlights how the space reimagines intensive care as more than just lifesaving technology.

Research underway and the outcomes clinicians want to track

Beyond immediate comfort, the hospital is collecting data to see whether regular outdoor exposure helps with measurable outcomes. Research elements include:

• Long-term recovery markers for patients discharged from intensive care.
• Stress and well-being measures for family members who spend time in the space.
• Staff stress levels and workplace resilience after using the rooftop as a restorative environment.

There is existing evidence linking access to nature with reductions in stress and blood pressure and improvements in mental health; the team at King’s aims to build specific evidence for critically ill populations and their caregivers.

Scale and purpose: who benefits from the roof garden

The rooftop is explicitly intended for people with serious, life-threatening conditions who would otherwise remain indoors. It supplements the King’s Critical Care Centre, which supports thousands each year—an ICU that cares for thousands of patients and their families annually.

• Patients: Extended stays in intensive care can be physically and mentally taxing; outdoor time offers sensory relief.
• Families: A calmer environment can reduce family stress during long hospital stays.
• Staff: Access to restorative green space can help reduce burnout and support compassionate care.

Practical takeaways and the wider conversation about nature and medicine

King’s rooftop demonstrates a growing movement to include nature in healthcare settings—sometimes called “social prescribing” or “nature prescriptions.” Proponents argue that carefully designed outdoor spaces can be therapeutic, clinically relevant, and cost-effective when paired with robust evaluation.

Key benefits the project seeks to deliver:

1. Lowered stress and anxiety for patients and families.
2. Potential improvements in vital signs such as blood pressure.
3. Stronger motivation for patients to engage in rehabilitation and recovery activities.
