"To express the platform and avoid destroying it is a very important thing, when you start building on top of it. A flat roof does not express the flatness of the platform...in the schemes for the Sydney Opera House...you can see the roofs, curved forms, hanging higher or lower over the plateau."
"The contrast of forms and the constantly changing heights between these two elements result in spaces of great architectural force made possible by the modern structural approach to concrete construction, which has given so many beautiful tools into the hands of the architect."
