Our conference on the 11th of May


Green Sky Thinking’s remit is simple: the sharing of honest lessons learned in sustainable design by the world’s leading community of built environment professionals. 


This year we have a rich programme running from 14-18 May of 25 events doing just that. In addition to our regular programme we’re sharing ideas and provocations too at a half-day get-together – the Green Sky Thinking Live Magazine – at the UCL’s Bartlett School of Architecture, to capture a more rounded picture of the city-making debate happening across London today. 


The mix of speakers and topics is broad: from character-led urban design methods at Brent Cross South with Argent, to the all-woman design and engineering leads on the VeloCity project, enhancing the Oxford – Cambridge corridor. We have reserved a spot to celebrate journalism too, and the ethical role it can play in making better cities.


We hope you enjoy this opportunity to share and enjoy new city-making perspectives shaped by a ‘people first’ philosophy. 

Kindly hosted by The Bartlett School for Architecture
