Codex Mellon at the Morgan

An example from the Codex Mellon.

The Morgan has posted a long series of plates online, depicting a wide range of architecture from Rome in the early 16th century. A gift from Paul Mellon, the collection has been dated to 1513.

Per the website:

Some of the most notable drawings in the Codex are related to the designs for St. Peter’s by both Bramante and Raphael, but it also records many contemporary and antique Roman structures including the Palazzo dei Tribunali and its church of S. Biagio della Pagnotta, both planned by Bramante for Pope Julius II; the interior of the Pantheon; and the elevation and cross section of the Colosseum.

Little is known about the draftsman responsible for the sketchbook. It has been variously attributed to Domenico Antonio (also called Menicantonio) de Chiarellis, a member of a family of stone carvers associated with Bramante, or to the sculptor-architect Domenico Aino da Varignana.

After Burnham: A Classical Plan for Chicago

Philip Bess, a professor at the University of Notre Dame’s excellent School of Architecture, is directing a fascinating project called After Burnham: The Notre Dame Plan of Chicago 2109. Building on principles of classical architecture, the plan envisions the future growth of Chicago over the next century in a more holistic pattern, drawing on the traditions and philosophy of Western urbanism in past eras, and using them to shape a modern city. Bess writes:

Modernity brings with it certain genuine human goods, and the successes of modernity can be measured in part by dramatic increases in human mobility, life span, and per capita income wherever modern institutions have established themselves. But these successes come at a price. Powerful accounts abound of the human suffering entailed in the transformation of traditional societies into modern societies; and the modern view of nature as raw material for human purposes has resulted in both the potential and the reality of environmental catastrophes at unprecedented scale (often with harshest impact upon the poor) and has created wholly modern eco-discontents. Last but not least, serious questions about the cultural sustainability of modernity arise in light of the individualist / therapeutic / consumerist character-type that modern societies seem to mass-produce.

A long western intellectual tradition dating from Aristotle views cities, character virtue, and human flourishing as intimately and reciprocally related. If true —and we think it is— this should give thoughtful people pause. Ours is a time of exploding urbanization in the modernizing societies of Asia, Africa and South America, and the aftermath of nearly seventy years of American suburbanization. Both of these phenomena represent distinctively modern forms of human settlement, but neither is typically evaluated holistically with respect to the relationship of urban formal order to environmentally and culturally sustainable human wellbeing.

See After Burnham for yourself. It’s a beautiful and fascinating proposal.

Camillo Sitte and The Art of Building Cities

I have a new article in the May-June print edition of TAC titled, “The Art of Placemaking,” about the substance and impact of Camillo Sitte’s 1889 book, The Art of Building Cities. Sitte focused on site design for urban spaces, and remains one of the most important aesthetic analysts of traditional European urbanism. A quote:

One of Sitte’s foremost concerns is the placement of monuments. Today, features like statues, sculptures, fountains, and obelisks may seem mere afterthoughts to core questions of urban planning. For Sitte, who considered the fine art of planning to extend down to the precise details of every urban space, such a presumption about ornament could not be more wrong. In his approach, the decision as to where a monument would be placed was as important as the choice of the object itself.

On his preference for irregularity in urban plans:

Always skeptical of overly rationalistic designs, Sitte is adamant about the value of irregularity. He contends that the modern desire for symmetry is misguided. Looking back to the history of the concept of symmetry, he writes:

Although [symmetry] is a Greek word, its ancient meaning was quite different from its present meaning…. The notion of identical figures to the right and left of an axis was not the basis of any theory in ancient times. Whoever has taken the trouble to search out the meaning of the word … in Greek and Latin literature knows that it means something that cannot be expressed in a single word today…. In short, proportion and symmetry were the same to the ancients.

For Sitte, the ancient meaning of symmetry is something closer to harmony than to a bilateral reflection. He argues that the more rigid definition is a product of Renaissance times that began to haunt the thinking of architects and planners, diverting them from the more nuanced harmonies of older, more irregular designs. Returning to the topic of public squares to apply this interpretive lens, Sitte notes that irregularities on the map are rarely discordant in actual experience. Instead, he contends that they can provide more interesting vistas, better proportioning, and even ideal sites for civic art:

The typical irregularity of these old squares indicates their gradual historical development. We are rarely mistaken in attributing the existence of these windings to practical causes—the presence of a canal, the lines of an old roadway, or the form of a building. Everyone knows from personal experience that these disruptions in symmetry are not unsightly. On the contrary, they arouse our interest as much as they appear natural, and preserve a picturesque character.

This point about urbanism is broadly consistent with Einstein’s famous observation that “The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.” As Raymond Unwin and others have observed, curved streets create an inherent sense of mystery, because their vistas reveal themselves only gradually, as one’s movement changes one’s perspective. That which has not yet become visible, but which we intuit to be there, compels us forward and holds our attention as it does so. Compare this to a typical grid, where streets, in the words of T. S. Eliot, “follow like a tedious argument.”

A web version of the article is up now, as well. Read the whole thing, and enjoy!

Raymond Unwin’s Town Planning

Sir Raymond Unwin

Did I mention that I recently published a long-form review of Raymond Unwin’s Town Planning in Practice at TAC‘s New Urbs?

The Unwin article is the first of a series of pieces that I’ve been writing about classic books of planning (which also includes my more recent piece at TAC about Allan Jacobs’ Great Streets). The idea behind these essays is that there is a canon of writings about the art of traditional, Western European urban planning. It begins, one might suppose, with Aristotle’s description of Hippodamus in his Politics; and continues down through the most timeless pieces of the last century. The landscape of these books is not always apparent; and over the last century, much the oral tradition of building that once sustained these practices dissipated in the face of heavy, technical regulation and the cultural trends of modernity. In light of the renewed interest in planning as an art — and as part of a larger cultural tradition — I think these writings deserve to be read, again, by a wider audience.

Distilling the Elements of Great Traditional Urbanism

My latest article at New Urbs looks at Allan Jacobs’ 1993 planning classic, Great Streets, and argues that the author’s focus on the necessary elements of placemaking, including the aesthetic details of urban planning, marked a turning point in the history of American urbanism. The entire piece can be found here.

 

Time for a Left-Right Consensus on Zoning Reform?

My latest piece — in which I venture into more political writing for TAC — argues that the failures of Euclidean zoning antagonize some of the most fundamental priorities of American traditions on both the Left and the Right; and that there may be an opening for some agreement between people with a broad range of philosophies. For example:

During the postwar era—when suburbs and cars were the way of the future, and cheap, undeveloped land surrounded all our cities—the postwar type of zoning seemed a reasonable trade-off for many conservatives. While it regulated the private land market, it was locally enacted. In addition, its intent was to protect a broad base of individual, private owners.

Today, things have changed. Many of our most prosperous regions have been effectively built-out—few undeveloped lots remain—and laws preserve building patterns from the less populous 1950s and 1960s. This in turn has created an artificial shortage of housing units to which local markets cannot respond. Property owners who could benefit from making more intense use of their parcels find their hands tied by local zoning. Families and individuals are priced out of regions where opportunities are strongest. Personal potential and mobility are limited. And local governments become powerful fiefdoms, selectively approving lucrative projects for (often) politically-connected developers while preventing smaller owners from similarly maximizing returns.

Meanwhile, from the Left:

If local zoning had simply permitted [working-class neighborhoods in major cities] to absorb growth as it occurred, it is likely many longtime residents would never have been priced out by rising rents or property taxes. This means that more young people could have remained in their home communities and benefited from deep ties to family, social networks, and local wealth; and space could also have been made for new immigrants (and internally-migrating Americans) on much friendlier terms. Instead, our inability to accommodate change at the neighborhood level has resulted in the attenuation of countless social ties; the loss of myriad old communities; and an increased degree of hostility and resentment between competing, but similarly powerless groups, over space that never needed to be so scarce. If anything should outrage even the most nominal leftist, it is a bureaucratic policy that pointlessly pits the American working class against new immigrants over something as fundamental as the need for decent housing.

Feel free to join in the discussion at the bottom.

Single-Family Houses and the Affordability Crisis

A zoning map from East Rockaway, New York, shows the abiding prevalence of single-family housing zones (Residence A) in a highly competitive land market.

This Times article, I think, really takes aim at the largest zoning-related cause of the housing crisis. Single-family neighborhoods will have to give way to multifamily development, one way or another, if we are ever going to build enough housing units to absorb demand in the places where economic opportunity exists. The California law facilitating “granny flats” is one step in the right direction. New Jersey’s Mount Laurel doctrine is based on a prescient, 1970s recognition of the exclusionary role of zoning. (Unfortunately, it has not done nearly enough to counter the zoning-driven shortage of affordable housing, especially in Northern New Jersey.

What other measures will come, based on the principle (which we have often recited) that restrictive zoning is creating artificial housing shortages? Innovation in this realm cannot happen soon enough. At some point, the dam is going to break. There will either be more housing; or there will be a dampening of the regional economies in places that cannot provide a housing equilibrium. What worries me, next, is that the artificial shortage of housing may have become such a chronic, long-term situation in our most affluent regions that we may have reached a point where the economy is dependent upon an artificial shortage being preserved.

Zoned for single-family.

That is to say, so many mortgages have been written on the assumption that astronomically high prices are stable; so much private wealth is now sunk into ultra-high-cost real estate. If the regulatory barriers came down, and builders were able to begin to catch up with market demand in places like New York City and California, then how much wealth would gradually begin to evaporate as prices trended toward a healthier equilibrium? The saving grace is that — absent a watershed court decision — the gears of this change will probably be quite slow to turn.

 

Limited Equity: Stable Communities, Affordable Housing

I have a new article published at TAC’s New Urbs blog, about the history and legal structure of New York City’s limited-equity housing cooperatives, which continue to provide surprisingly affordable, high-quality housing units in one of the most expensive real estate markets in the United States. The piece tells the story about how limited-equity co-ops got started; their philosophical roots; their early successes; why the model declined in popularity; and how an approach that recovers its best qualities might be be compatible with various subsets of the polarized political landscape of contemporary America.

I think there’s little question that the shortage of affordable housing in the regions with the best economies is a major driving force in the structural inequality that characterizes our current moment; and that the biggest beneficiaries of this status quo are rent seekers, rather than actors who contribute anything dynamic or innovative to the economy. Taking the role of speculation out of the equation can do a lot to keep prices in line with what residents can actually afford. For the reasons described in my article, I think this is an important idea that deserves to be recovered and applied in today’s metropolitan real estate economies.

California’s Radical Experiment: Granny Flats

Most would not be as fancy as Alexandre Dumas’.

Driving home from the train station on a recent night, I heard this piece on NPR’s Marketplace: a story about a recent California statute that makes it significantly easier for homeowners in that state to develop additional units on their property. Here’s a link to a memo from the Department of Housing and Community Development, describing the changes. Among other things, the new statute overrides certain off-street parking requirements, which can preclude new units that would otherwise be permitted under zoning rules. These requirements are particularly onerous in large cities where public transportation is a viable option — and this law takes aim, specifically, at requirements within walking distance of transit. Of course, this development is just a small step toward achieving a land marketplace that is actually allowed to be responsive to market demands, rather than legal ones; but I think it is a very important one.

As early as the mid-1970s, the primary cases in New Jersey’s Mount Laurel doctrine began to lay out all of the major land use regulatory devices that have stifled the development of resourceful housing options since the early 20th century. Getting rid of unnecessary off-street parking requirements, and taking a publicly favorable stand toward in increase in the number of units in heavily-regulated suburban neighborhoods, are both major steps toward dismantling the regulatory morass that has been strangling housing development as the amount of raw, zoned land has dwindled throughout our major metropolitan areas. This is an important step in the right direction. Would be interested in hearing from people who would like to see a similar bill in New Jersey.

One of the most important takeaways from the NPR story was its hard evidence of pent-up demand for smaller, less-expensive housing units in pricey California. Local builders and contractors who specialize in the construction of small homes cannot keep up with demand. Their schedules are full for months into the future.

Shaping the Urbanism of Victorian America

 

I’m happy to report that The American Conservative, in its New Urbs featurehas published my article about the key factors that shaped Late Victorian urbanism in the United States. My piece focuses on this period before zoning, and explores the physical, legal, economic, and cultural phenomena that drove neighborhood development in the absence of comprehensive plans. I chose this period because it has intrigued me for a long time; and because so much of the New Urbanism of today seems to be imitating the forms of that era without necessarily asking the important questions about the larger context that created them. TAC deserves credit for taking a lead in discussing the important dynamic between urban form, society, and sustainable communities. Here’s a nice piece by executive editor Lewis McCrary about the walkability of New Jersey shore towns, many of which I have walked through, and many of which have an urban fabric that dates from the same period that my article describes.
