PTE will be exhibiting two featured projects at the RIBA Architecture Open Exhibition. Entrants were asked to submit work under the theme of 'Unseen' - these could be competition entries, conceptual projects, paintings, drawings and models relating to projects, built or unbuilt, that have not yet had a great deal of (or any) exposure. The aim is to give these projects a platform and show the breadth and quality of work that our members produce. The exhibition will be open to the general public from 6 October - 4 November 2011 at the RIBA, 66 Portland Place, London W1B 1AD.
