Plasma Studio was founded in 1999 by Eva Castro and Holger Kehne who combine their practice with teaching in the AA's Diploma School and Landscape Urbanism programme. Castro and Hehne present a selection of built work, competition entries, and current projects. The lecture coincides with the Plasma Studio exhibition in which the radical architecture of their fourth-floor lobby of the Hotel Puerta Amrica is reconfigured in order to create a bespoke environment that responds to the specific proportions and geometries of the AA Gallery.
