This is a small square-ish book with a lime green cover and metallic purple type on the cover. Inside it is slightly less garish. It is full of conceptual architecture, some of which probably has not been built, with a decent accompanying text. Although the photography is from a variety of sources, you would not tell looking through it. No disturbing seventies furniture or other discordant elements. All in all it is attractive and provocative. I don't think you would want to live in any of these structures, but they do make you think.
It includes structures to hang off a rockface, or stand on a single leg in a lake, shelters, and sculptural art objects.
For me, the book was not always legible, text against coloured backgrounds or of a very light weight. But overall this is attractive and very well produced, if you like buildings to make you think, then this is the book for you.
This is the first book in the series that I have read and I'll definitely be looking for the other two.
