Last week saw east London take a jolly green giant step forward as The Crystal – one of the world’s greenest buildings – was officially opened by notorious dangler BoJo. The peculiarly shaped (even by London’s standards), glass-clad building houses the world’s largest interactive exhibition dedicated to the future of cities with a strong focus on sustainable living, urban infrastructure and even health care. Despite its virtuous façade, The Crystal is primarily a conference centre and the new Siemens flagship. Though the building may not be ball shaped, head down to Royal Docks and peer into the future now. Carly-Ann Clements
