If you want to change the world, you need to start with great ideas. This volume focus in particular is on the cutting-edge thinking and wider theoretical questions and themes that underpin the series, from reflections upon what our ideas of "future" really mean to the changing role of the architecture profession as a whole.

This volume comprises speculative visions, essays and texts from contributors including: Ana Jeinic, Milos Kosec, Clement Blanchet, Amateur Cities, Liam Young, Something Fantastic, Merve Bedir, Tomaz Pipan, Davide Tommaso Ferrando, Tiago Torres-Campos and Reinier de Graaf.
