Khoo Teck Puat Hospital in Singapore has incorporated lush greenery throughout its building, hiding the scent of medicine and chemicals with more than 700 species of plants. Birds have been introduced in the central courtyard, and doctors, visitors and patients can walk along outdoor bridges covered in greenery. Patients are given organic food from the hospital’s own rooftop garden, and the complex practices Meatless Mondays—all with the aim of creating a ‘total healing environment’. While no scientific studies confirm whether the hospital’s greenery, natural light and increased sense of community have an effect on healing, patients appreciate the beautiful design and often say they are willing to pay more to stay there. Other evidence demonstrates that greenery and natural light can boost recovery—which may account for Khoo Teck Puat’s success.
