A pop-up garden, designed by RHS Young Designer of the Year Tony Woods, has been installed on the roof of John Lewis in Oxford Street. Edged with curved, chest-high raised beds, the garden has views to landmarks across the capital, while a living wall section hides less attractive buildings. The space is also designed to attract insect life, especially with the meadow roof on the traditional bandstand. A greenhouse frame creates a setting for more exotic plants such as palm trees and aeoniums. Open daily 10am-4pm (11.30am-4pm, Sundays).
