Pre-Planning Layout

I don't really like large amount of white spaces, so I want to pre-plan my layout to take up the space as much as possible. I'll fill them in with sections, elevations, details of the "Slim" building.

My first attempt was to use a verticals and horizontal format, like a grid. My final thought on it is that it's too boring. No excitement and too plain. I want the draws to flow and excite my audience. Here's my pre-plan of what I am going with. Some drawings are missing because I have not yet draw them...still in the process to complete them.
