This lecture examines the evolution and key principles of High-Tech Architecture, focusing on the integration of advanced technology, structural expression, and spatial flexibility in building design. It discusses early precedents such as the Eames House, which anticipated high-tech ideas through modular construction and visible structural systems, and analyzes major projects like the HSBC Headquarters to illustrate collaboration between architects, engineers, and manufacturers in developing precision-engineered building components. The lecture also explores concepts such as exposed structures and services, technological aesthetics, and flexible interior spaces, highlighting the idea of Omniplatz, where open, serviced interiors allow buildings to adapt to changing functional needs over time.
