Style guide design

So I have researched a few different kinds of style guides and have found that a few of the most useful designs are from Coca Cola, Batelco and Burj Dubai each of which were a part of the links on moodle. I found that coca cola and Burj Dubai style guides were useful to see how to set out a colourful and interesting design using a very simple three column grid system. All these style guides were also in landscape format which is what I want to use to set out my own Sustenance style guide and branding book.
