This course is focused on the critical study of spatiality of the built environment by means of sketching and free-hand drawing. It involves intensive hands-on exercises that are to be supported by weekly individual feedback, intervening lectures, collective comments, and group discussion. Exercises will be carried out on pre-selected locales of different kinds and progressive complexity and difficulty. Attention is directed to the critical process of seeing, understanding, conceptualising, and producing interpretive drawings rather than documentary ones, emphasising architectural spatiality and atmosphere constituted and/or enhanced by certain aspects of the objects, such as form, detail, material, texture, light, and overall setting, which capture the mind upon viewing.
