Love it or hate it, 20 Fenchurch Street – better known as the Walkie-Talkie building – has the capital’s highest public garden space. Sky Garden includes lush vegetation, an open-air terrace and 360-degree views of the city. It’s free to visit, but you have to book in advance.
The Barbican Centre is famous for theatre and art, but it is also home to the second-biggest conservatory in London. Its 23,000 sq ft tropical sanctuary contains exotic fish and more than 1,500 plants, while on Sundays it transforms into a unique setting for afternoon tea.
For picnics, why not eat in Waterlow Park near Highgate Cemetery, or in the walled garden inside Brockwell Park near Brixton?
