Additive Approach

I thought of this additive approach to be like a tree. Starting from one point, it grows and branches out to more extensions. Note how the base has more units then the higher up elevations. I added an off nub on one side to be like a 'baby branch.'

Subtractive Approach

This is the subtractive approach. I tried to create a distinctive pattern or symbol on each side by cutting away pieces. Like seen in the two elevations, I created 'lines' by either cutting them out or cutting out boxes to contrast the lines.
