This publication is the proceedings of all the papers accepted and presented at the 13th biennial International Conference of the European Architectural Envisioning Association. The conference – with the theme Envisioning Architecture : Space/Time/ Meaning – was held in the Glasgow School of Art in September 2017 and was organized my the Mackintosh School of Architecture and the School of Simulation and Visualization, with assistance from the City of Glasgow College. It coincided with an Exhibition of original drawings of Scotland’s other renowned architect Alexander “Greek” Thomson, hosted by The Lighthouse - the nation’s Centre for Architecture and Design. The papers - in approximate equal numbers from Europe, North America and Japan, offer an eclectic representation of the variety of ways in which we envision architecture and its related disciplines, from analogue to digital. No attempt has been made to classify them – rather they are presented as they were received, to stimulate diversity, cross-reference, comparison and inspiration
