Space Station Complex was designed for reconfiguration and modular growth . The common core and independent maneuvering capabilities of several of the modules have allowed the complex to be rearranged several times as it has grown.
Urban planning has an uneven history of success.
For instance, Washington D.C. was laid out according to a master plan designed by the French architect L'Enfant . Other cities, such as Houston, have grown without any overarching plan to guide them. Each approach has its problems. For instance, the radial street plans in L'Enftant's master plan become awkward past a certain distance from the center. The lack of any plan at all, on the other hand, leads to a patchwork of residential, commercial, and industrial areas that is dictated by the capricious interaction of local forces such as land ownership, capital, and zoning.
