President Obama's establishment of an Urban Affairs Office again spotlights the need for design of the urban environment which goes far beyond economic exploitation dominated by the real estate and construction industries which has produced ugly chaos in buildings and infrastructure. Mastering the complexities of cities and the forces which shape them is difficult but necessary for sound comprehensive design; otherwise piecemeal endeavors so beloved by dealmakers seeking favorable privileges produce projects of reduced public benefit. To counter aggressive, narrowly-interested manipulators of the urban fabric, design tools are needed to research, study, explore and propose benefits for city dwellers. Brian McGrath's "Digital Modelling for Urban Design" will be welcomed by urban designers faced with daily barrages of commercial demands to forgo overall public interest and concentrate on the avarice of property developers and their batteries of biased financial, legal and design professionals. With the tools he describes it will be possible to reinforce the original purpose for founding urban design: the design, production and preservation of livable, healthy, safe and beautiful cities for all their inhabitants not merely the few who think they rule as their own what belongs to all.
