There are two sources of light in architecture: 'natural' and 'artificial'. Natural light is provided by the sun. It is unpredictable. We cannot easily control it. We must build our environment around it.

Artificial light has evolved as a technological response to the need to illuminate our world after dark. We can both create and control it. We can design both the source and the subject. Throughout civilisation the form of our architecture has responded to the sun. Until the industrialisation of artificial lighting the limits of technology resulted in these light sources being limited to function and utility.

We now live in an age where artificial sources offer as many possibilities for expression and the creation of architecture as the light of the sun itself.
