Architectura Poetica - Art as Object. The poeticus of this project, the objective elements, are those things concerned with the timely; the means of construction; the structure itself; the non-parallel walls desired in spaces for music. These are expressions <i>about</i> Architecture. Architectura Practica - Art as Event.

They are impressions of the objective elements: public/private, dynamic/static, light/dark, formal/informal, inside/outside. These are expressions <i>of</i> Architecture. / Master of Architecture
