We were presented with a sloping Industrial site, and given the mandate to create what would make the most profits.  The answer was a 4 story warehouse with over 18,000 square feet of storage and office space.  The slope gave us the ability to enter three of the levels at grade, with the upper-most floor being accessed via stair and a roller door for fork lift access.  This eliminated the expense of an elevator which would eat up floor area on every level.  We also paid our respects to the neighbors to the north with a more residential treatment to that elevation.  The design was successful, and represents proof that Architecture does not need to take a back seat when the goal is simply to maximize profits.
