A diversity within its unity The vital power of an imaginative work demands a diversity within its unity; and the stronger the diversity, the more massive the unity. Dorothy Sayers, The Mind of the Maker diversity
The heat death of design Losing the design diversity means falling into a singular narrative of how design must be done, which grants unfair and self-reinforcing advantage to the mainstream while discouraging, stifling, or even punishing the idiosyncratic designers who bring unorthodox but remarkably innovative processes to the table. The true opportunity cost is the diverse future that humanity can no longer access. A future without diversity is fundamentally stagnant: imagine designs so standardized that you can’t tell them apart. While every design is guaranteed to be good, none will be great. New designs are marginally better than previous ones with the rate of improvement eventually approaching zero. We have reached the heat death of design. Chuánqí Sun, The vanishing designer diversity
Obsessed with absolute numbers Modernist planning was obsessed with absolute numbers, including the minimum dimensions of rooms, open space per capita, and the one-size-fits-all head counts of neighborhood units. This was often pegged at five to seven thousand and was used as a formula for determining the distribution of schools, shops, sports fields, and other facilities. The failure of such planning is not in its effort to be comprehensive or to equalize access to necessary facilities. It is, rather, the attempt to rationalize choice on the basis of a homogeneous set of subjects, a fixed grammar of opportunities, a remorseless segregation of uses, and a scientistic faith in technical analysis and organization that simply excludes diversity, eccentricity, nonconforming beauty, and choice. The utopian nightmare. Michael Sorkin, 20 Minutes in Manhattan Desired qualities of lightPredicted Mean Vote planningmetricsdiversity
The number of ways in which things work The importance of diversity is not so much the number of elements in a system; rather it is the number of functional connections between these elements. It is not the number of things, but the number of ways in which things work. Bill Mollison, Introduction to Permaculture diversityconnectionnetworkssystems
Exuberant diversity in a city's streets To generate exuberant diversity in a city’s streets and districts, four conditions are indispensable: The district, and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two. These must insure the presence of people who go outdoors on different schedules and are in the place for different purposes, but who are able to use many facilities in common. Most blocks must be short; that is, streets and opportunities to turn corners must be frequent. The district must mingle buildings that vary in age and condition, including a good proportion of old ones so that they vary in the economic yield they must produce. This mingling must be fairly close-grained. There must be a sufficiently dense concentration of people, for whatever purposes they may be there. This includes dense concentration in the case of people who are there because of residence. Jane Jacobs, The Death and Life of Great American Cities diversitystreets

A system for living Unlike the traditional neighborhood model, which evolved organically as a response to human needs, suburban sprawl is an idealized artificial system. It is not without a certain beauty: it is rational, consistent, and comprehensive. Its performance is largely predictable. It is an outgrowth of modern problem solving: a system for living. Unfortunately, this system is already showing itself to be unsustainable. urbanism
The five components of sprawl The dominant characteristic of sprawl is that each component is strictly segregated from the others. Housing subdivisions, also called clusters and pods Shopping centers, also called strip centers, shopping malls, and big-box retail Office parks and business parks Civic institutions Roadways
Subdivisions Subdivisions can be identified as such by their contrived names, which tend toward the romantic—Pheasant Mill Crossing—and often pay tribute to the natural or historic resource they have displaced.
An unmade omelet The successes of turn-of-the-century planning, represented in America by the City Beautiful movement, became the foundation of a new profession, and ever since, planners have repeatedly attempted to relive that moment of glory by separating everything from everything else. This segregation, once applied only to incompatible uses, is now applied to every use. A typical contemporary zoning code has several dozen land-use designations; not only is housing separated from industry but low-density housing is separated from medium-density housing, which is separated from high-density housing. Medical offices are separated from general offices, which are in turn separated from restaurants and shopping. As a result, the new American city has been likened to an unmade omelet: eggs, cheese, vegetables, a pinch of salt, but each consumed in turn, raw.
Beauty and function In truth, a lot of sprawl—primarily affluent areas—could be considered beautiful. This raises a fundamental point: the problem with suburbia is not that it is ugly. The problem with suburbia is that, in spite of all its regulatory controls, it is not functional: it simply does not efficiently serve society or preserve the environment.
Six qualities of traditional neighborhoods The center The five-minute walk The street network Narrow, versatile streets Mixed use Special sites for special buildings
Market segments The segregation of housing by “market segment” is a phenomenon that was invented by developers who, lacking a meaningful way to distinguish their mass-produced merchandise, began selling the concept of exclusivity: If you live within these gates, you can consider yourself a success.
Cookie cutter One term that gets a lot of play these days is “cookie cutter.” Developers are mortified about the way this term is used to describe their subdivisions, and they expend a good deal of energy—and money—avoiding it. As much as 20 percent of their construction budget goes toward the application of superficial variety—different shapes, colors, window types, different styles of tack-on ornament, French Provincial next door to California Contemporary. But these efforts are in vain, because beneath the surface articulation is a relentless repetition of the same building. The best way to create real variety is to vary not the architectural style but the building type. Indeed, in places like Georgetown, styles vary only slightly, but one never hears the term cookie cutter, thanks to the wide range of building types.
Worthwhile destinations Pedestrian life cannot exist in the absence of worthwhile destinations that are easily accessible on foot. This is a condition that modern suburbia fails to satisfy, since it strives to keep all commercial activity well separated from housing.
The twenty-minute house Despite the way that it sounds, the “twenty-minute house” is not a derogatory label. Quite the opposite—it refers to the fact that a house has only twenty minutes to win the affection of a potential buyer, since that is the average length of a realtor visit. The building industry has responded to this phenomenon by creating a product that is at its best for the first twenty minutes that one is in it.

Homebuilders The term homebuilder describes the house as a product that exists independent of its context. This approach would be appropriate if houses floated freely in space, or in some other environment where actual interaction between neighbors was neither possible nor desired. But houses are not meant to exist in isolation, so to think of the individual house as the ultimate outcome of the builder’s craft robs that craft of its broader significance. context
The cul-de-sac kid In this environment where all activities are segregated and distances are measured on the odometer, a child’s personal mobility extends no farther than the edge of the subdivision. Even the local softball field often exists beyond the child’s independent reach. The result is a new phenomenon: the “cul-de-sac kid,” the child who lives as a prisoner of a thoroughly safe and unchallenging environment. This “isolation and boredom” is the outcome of an environment that fails to provide teenagers with the ordinary challenges of maturing, developing useful skills, and gaining a sense of self.
On-site parking Most cities require new and renovated buildings to provide their own parking on site. This is probably the single greatest killer of urbanism in the United States today. It prevents the renovation of old buildings, since there is inadequate room on their sites for new parking; it encourages the construction of anti-pedestrian building types in which the building sits behind or hovers above a parking lot; it eliminates street life, since everyone parks immediately adjacent to their destination and has no reason to use the sidewalk; finally, it results in a low density of development that can keep a downtown from achieving critical mass.
Architectural mysticism In response to their growing sense of insignificance, some architects have tried to regain a sense of power through what can best be described as mysticism. By importing arcane ideas from unrelated disciplines—such as contemporary French literary theory (now outdated) —by developing illegible techniques of representation, and by shrouding their work in inscrutable jargon, designers are creating increasingly smaller realms of communication, in order that they might inhabit a domain in which they possess some degree of control. Nowhere is this crisis more evident than in the most prestigious architecture schools. architecture
