Since this piece of property is so close to a metro station, you can take this strip mall and turn it into a 20 floor tower. Want to stand out? OK, you can build up to 300 feet. The ultimate plan is to create a real city environment for a suburban county. Walkable, intriguing.
Why not taller? Inflating real estate prices= more lateral development= quicker means to a citylike environment.
Addendum: "We built this place up from scratch with the help of greedy developers". Well, there was a historic downtown Rockville, much like Leesburg, VA or Frederick, MD. It was torn down for the lovely brutalist towers, most notably 51 Monroe, as an early "Transit-oriented development" (It's connected by skywalk to Metro Rockville).
