Atlanta development has been crazy the last several years. We used to have a lot of separate buildings getting built, but lately the trend is to build entire neighborhoods or mega-projects.
Probably because the city is poorly connected with highways running through it. OTOH the "whole neighborhood development" thing can be very nice.
