Did I miss something? I thought you said 5 groups of 5x5x5 cubes stacked 2 high. That's only 125 sqft. Wouldn't it be cheaper to make a separate space, either with two hour walls or to just extend the coverage beyond the area with the higher demand as per NFPA. The solution seems so obvious and simple but as I believe it was Twain who said, "For every problem there is a solution that's simple, obvious, and wrong." so I suspect mine is falling into that category and believe I must have missed something in the explanation.
