Take a look at the new Charlotte county courthouse.

Building architecture aside, the layout is designed in a way that also encourages foot traffic at street level.
A. The midrise building (its nine stories) uses a compact space of land. This means every single square inch of the property is used, as opposed to leaving patches of left over unusable open space. The layout also creates a covered walkway along the street edges, protecting through foot traffic from oppressing heat or rain storms. Chalk that up as a plus for the pedestrian.
B. The courthouse, like many office towers, has its own cafe space. However, the cafe fronts the street and was designed to have a separate entry from the main courthouse entrance. This design features makes the cafe a secondary focal point that can pull in street traffic at another street corner and generate foot traffic between the two entry points.
C. The backside of the building contains a public outdoor plaza, with a secondary entrance to the main courthouse atrium space.

The entry points are strategically placed to generate foot traffic around the entire block limiting dead zones. So when we throw out costs (its cheaper to go vertical), the height does not matter. Its more about designing the interior spaces in a fashion that serves the courthouse's needs and stimulates foot traffic for additional growth in the area of downtown its located in. For $350 million, we should be able to do better.
