Crisis! What Crisis? Retooling for Mass Markets in the 21st Century

From his base in Southeast Asia, Tom Verebes , Associate Professor in the Department of Architecture at the University of Hong Kong (HKU), asks what the hardcore realities are for robotics in architecture in this new ‘Asian Century’. At a time when China strives to accommodate 10 million new urban citizens each year by rolling out high-rise residential blocks with standardised serial production techniques, what hope is there that the homogeneous Chinese city will apply robotic tools of mass customisation for the construction of distinctive, rather than generic structures?     

A Deeper Structural Theory

The architectural critic and author Nina Rappaport celebrates a new structural synthesis that takes a holistic approach to tectonics, uniting the bones or structure of a building with its skin. She calls for a new structurally based theory that effectively fuses culture and technology, embracing ‘deep decoration’ and ‘subtle innovation’ and reviving a design tradition that can be traced back to AWN Pugin and John Ruskin.
