Testimonials
Encyclopaedic in its depth and completely unique and comprehensive. It should be an ally to any architectural designer - student or experienced professional. This is the best piece of architectural writing I've seen, if only I had this a decade ago throughout my university years - a lot of mistakes would've been avoided. Incredible work.
