ABSTRACT
The framework of themes in this book is not complete. There are many still to be identified; and probably an unlimited amount to be invented.
I am aware of some that I have not had space to include: the theme of ‘datum place’—a place by reference to which one knows where one is; the theme of ‘places made by excavation’, rather than by building; the theme (related to transition, hierarchy, heart) of ‘places between’—places within wallszones between inside and outside which are not quite either; the theme of ‘implied place’— that place is not always clearly defined by basic and modifying elements of architecture, but can be implied in minimal and subtle ways; and then there is the theme of ‘non-orthogonal architecture’ (which has only be touched upon here)—where orthogonality and the six-directions-plus-centre are denied or subverted.
