Our Urban Environment

Problem

There is abundant evidence to show that high buildings make people crazy.

Solution

In any urban area, no matter how dense, keep the majority of buildings four stories high or less. It is possible that certain buildings should exceed this limit, but they should never be buildings for human habitation.

This is the first site along the tour. In here we have a void. I remember the building that used to stand here, it was painted blue. Passing through it, you can imagine how us, as ghosts – should the building be standing here – would have to actually be invisible to pass through these walls and now it’s the reverse. The building is the ghost and we’re passing through these walls.

The linear city was an urban plan for an elongated urban formation. The city would consist of a series of functionally specialized parallel sectors.

As the city expanded, additional sectors would be added to the end of each band, so that the city would become ever longer, without growing wider.

All cities can be described as a dialogue between homogeneity and exception, and each strikes a particular balance that is at the core of its character.

Imagine that our rooftops were parkland, that the area of ground occupied by buildings was, in effect, simply displaced upward. Imagine that the city enacted legislation requiring that the equivalent of 100 percent of the surface area of New York were to be green. A 100 percent requirement would not simply oblige green roofs. It would also demand that compensatory greenery be added to make up for such ungreenable areas as roadways, runways, and other unplantable places. Perhaps the requirement would be satisfied with road narrowings, cantilevered gardens, or green floors in buildings (utilities on the order of the mechanical floors that occur in almost all tall buildings).

The contents of the city’s images which are referable to physical forms can conveniently be classified into five types of elements: paths, edges, districts, nodes, and landmarks.

1. Paths are the channels along which the observer customarily, occasionally, or potentially moved.
2. Edges are the linear elements not used or considered as paths by the observer. They are the boundaries.
3. Districts are the medium-to-large sections of the city, conceived of as having two-dimensional extent.
4. Nodes are points, the strategic spots in a city into which an observer can enter, and which are the intensive foci to and from which they are traveling.
5. Landmarks are another type of point-reference, but in this case the observer does not enter within them, they are external. They are usually a rather simply defined physical object: building, sign, store, or mountain.

Does a concert hall ask to be next to an opera house? Can the two feed on one another? Will anybody ever visit them both, gluttonously, in a single evening, or even buy tickets from one after going to a performance in the other?

In Vienna, London, Paris, each of the performing arts has found its own place, because all are not mixed randomly. The only reason that these functions have all been brought together in Lincoln Center is that the concept of performing art links them to one another. The organization is born of the mania every simple-minded person has for putting things with the same name into the same basket.

There is a basic esthetic limitation on what can be done with cities: A city cannot be a work of art.

Dr. Weaver lists three stages of development in the history of scientific thought: (1) ability to deal with problems of simplicity; (2) ability to deal with problems of disorganized complexity; and (3) ability to deal with problems of organized complexity.

The history of modern thought about cities is unfortunately very different from the history of modern thought about the life sciences. The theorists of conventional modern city planning have consistently mistaken cities as problems of simplicity and of disorganized complexity, and have tried to analyze and treat them thus.

These loose notes are one possible description of our city. A city that, as in Constantin Cavafy’s poem The City, is and always will be the same, in the same city again.

For the human mind, the tree is the easiest vehicle for complex thoughts. But the city is not, cannot, and must not be a tree. The city is a receptacle for life. If the receptacle severs the overlap of the strands of life within it, because it is a tree, it will be like a bowl full of razor blades on edge, ready to cut up whatever is entrusted to it. In such a receptacle life will be cut to pieces. If we make cities which are trees, they will cut our life within to pieces.

I want to call those cities which have arisen more or less spontaneously over many, many years natural cities. And I shall call those cities and parts of cities which have been spontaneously created by designers and planners artificial cities. Siena, Liverpool, Kyoto, and Manhattan are examples of natural cities. Levittown, Chandigarh, and the British New Towns are examples of artificial cities.

It is more and more widely recognized today that there is some essential ingredient missing from artificial cities.

“Tree is leaf and leaf is tree – house is city and city is house. A city is not a city unless it is also a huge house – a house is a house only if it is also a tiny city.”

— Aldo van Eyck

To become completely lost is perhaps a rather rare experience for most people in the modern city. We are supported by the presence of others and by special way-finding devices: maps, street numbers, route signs, bus placards. But let the mishap of disorientation once occur, and the sense of anxiety and even terror that accompanies it reveals to us how closely it is linked to our sense of balance and well-being. The very word “lost” in our language means much more than simple geographical uncertainty; it carries overtones of utter disaster.

The junction, or place of a break in transportation, has compelling importance for the city observer. Because decisions must be made at junctions, people heighten their attention at such place and perceive elements with more than normal clarity. This tendency was confirmed so repeatedly that elements located at junctions may automatically be assumed to derive special prominence from their location.

There are dangers in a highly specialized visible form; there is a need for a certain plasticity in the perceptual environment. If there is only one dominant path to a destination, a few sacred focal points, or an ironclad set of rigidly separated regions, then there is only one way to image the city without considerable strain. This one may suit neither the needs of all people, nor even the needs of one person as they vary from time to time. An unusual trip becomes awkward or dangerous; interpersonal relations may tend to compartmentalize themselves; the scene becomes monotonous or restrictive.

Among real-estate developers, straight lines and right angles went out of fashion sometime in the middle of the twentieth century. If you look at a town or a residential neighborhood laid out since then, you are more likely to find sinuous, serpentine roads—whether or not the topography offers any excuse for such curves. Many of these roads go nowhere: they are loops that bring you back to where you started, or they are cul-de-sacs. Making it easy to find your way through the network of streets is obviously not a high priority. This is an interesting development in urban geography: having redesigned the city to accommodate the automobile, we now search for ways to discourage people from driving on the streets.

If you can understand a city, then that city is dead.

“See, what I’ve always liked about Los Angeles is that it’s one of the least restrictive towns in the world. You can pretty much live any way you want to here. And part of that is because the place has no tradition and no history in that sense. It doesn’t have any image of itself, which is exactly its loss and gain. That’s why it’s such a great place to do art and to build your ideas about culture. In New York, it’s like an echo chamber: its overwhelming sense of itself, of its past and its present and its mission, becomes utterly restricting.”
