The Jetty In Greenwich The Jetty @ Greenwich is one of our most interesting sites. Made up of 7 polytunnels side by side, this is a huge growing and event space with a tropical climate on the River Thames. Inside, The Jetty is a lovely, warm, soft-lit spot perfect to bring people together. Being surrounded by plants creates a colourful, relaxing space that lets your mind wander!
