My longtime neighborhood, the Lower East Side of Manhattan, represents for me some of the best qualities of urban living. Among its defining characteristics:

A Walk Score of 96 (out of 100, meaning I can happily exist without that American appendage, the automobile),

Density high enough to enable a richness of community and cultural vitality but not so high as to lose a sense of local identity,

Ethnic and economic diversity due to preservation of many of the low-rise century-old buildings, Street vitality and community arising from the varied possibilities for human interaction, and

A structural resistance to chain and big box stores due, again, to the existing building stock.

So I’ve been following with great interest the influx around us of high-rises in the past decade, a movement that will reach a crescendo with the proposal to finally build out a long contemplated – and long fought – massive redevelopment in the center of the LES.

For most of the previous 50 years or so, since the last of the post-Robert Moses urban renewal projects were completed, the LES retained most of its low-rise urban fabric of tenement buildings with mom-and-pop stores at the street level. True, the neighborhood was hit hard by the one-two punch of NYC’s fiscal crisis of the 70s followed by the epidemic of crack in the 80s. Though not as severe as the South Bronx, there were plenty of abandoned, sometimes burned out buildings interspersed with garbage strewn vacant lots. Both of the LES buildings I’ve lived in during my 31 years here had been empty and scheduled for demolition until early gentrifiers like me came in and gut renovated them.

The newer buildings, the mid-20th century urban renewal projects, generally adhered to the much maligned and discredited “tower in the park” approach to urban design in which high-rise apartment buildings were set back from the street and surrounded by open space. While there are some successful versions of this, such as Stuyvesant Town, the majority of them became characterless semi-isolated towers embedded in sometimes unsafe public space. The worst of them, like the infamous Pruitt Igoe project in St. Louis, had to be demolished because they were so dangerous. And from an urban vitality point of view, this concept of urban design abandoned the street, eliminating the activity, safety and community that looked messy and outdated to planners but, we discovered, are the backbone of urban neighborhoods.

The more recent influx of development has taken the forms of both conventional towers fronting on the major streets (Houston and Delancey streets, and the Bowery, for the most part) and mid-block “sliver towers.”  The latter have been very controversial for their practice of buying up the “air rights” of surrounding older buildings and transferring the square footage to the mid-block site, thus allowing these new buildings to be far higher than the zoning would have permitted. More on that in a moment.

Amidst this, the Seward Park Urban Renewal Area (SPURA), one of the largest development sites remaining in Manhattan, is finally moving ahead. Following an RFP this spring, the NYC Economic Development Corporation awarded the entire project to a developer team (the EDC could have chosen to award any of the nine sites to individual developers, which might have resulted in a less monolithic look) and the proposed design was revealed a few days ago.

In some Op-Ed pieces (here is one of them) I wrote during the RFP period, I expressed concern about the urban aspects of the project’s criteria as developed by the EDC. While the local community board did heroic work in demanding affordable housing and limiting big box stores, my fear was that the design proposals would follow the common contemporary formula: whole block buildings with uniform street walls and slightly set back anonymous looking glass towers.

(This was in addition to my other objection – the EDC’s insistence on providing an additional 500 parking spaces beyond the maximum allowed by the zoning. This approach reflects a long-standing and outdated car-oriented policy of theirs. One result of it is the empty and soon to be demolished brand new parking garage at the new Yankee Stadium.)

The primary architect of the SPURA proposal is the hot firm SHoP. Their work is often fresh and interesting, as evidenced by local designs such as the Barclays Center. (Interestingly, that project could be seen as the opposite of SPURA in that the controversy there mostly revolved around demolition of existing housing and the dramatically increased density of the not-yet-built buildings that will adjoin the arena. Back here, most of the sites have been long vacant since the existing housing was torn down 50 years ago, and the open parking lots have been what I’ve termed the “black hole” of the Lower East Side. Since those sites are empty, no one is objecting to building there. The questions centered on how it would relate to the surrounding area and how it could improve the community.)

SHoP’s renderings, while not as bland as the other nearest redevelopment project, Avalon Bowery, still succumbs to the whole-block building syndrome which, in spite of amenities like roof gardens, results in unrelenting forms that are devoid of relationship to their surroundings.

Which begs the question: what’s the alternative? Many would say (as in fact I have in other situations) that the approach should be to take the best of adjoining neighborhood – presuming there are positive aspects to the neighborhood – and improve upon them. This would have the effect of strengthening local roots rather than inserting a wholly new and out of character “intervention,” as this is sometimes called in archispeak.

The problem with this approach, of course, is money. Urban land is valuable and construction is expensive, so developers insist on density. On the community side, limiting the amount of housing inexorably pushes up prices, often forcing existing residents to leave.

So, as desirable as it may be from a contextual point of view, low density development is not realistic in urban cores. Is there a way to accommodate the economics without forsaking community character? There is and, though it may evoke outcries at first, it’s not far different from the sliver tower concept.

I first contemplated this conundrum – how to increase density without losing the appeal of older urban streets – in a design competition back in 1985 for urban infill housing in Harlem, “Reweaving the Urban Fabric: Approaches to Infill Housing.” My entry proposed filling in the vacant lots with new buildings similar in scale to the existing walk-ups, and then adding what in essence was a new layer of shallow towers above. The concept was that the lower level buildings would be primarily for families and the upper levels would focus on smaller apartments for singles, couple and seniors. Multigenerational buildings were not yet a topic, but it was implicit in the idea.

Interestingly, the day after the SPURA design was released, I received a copy of the Yale School of Architecture’s annual publication Retrospecta in which the previous year’s student work is shown and discussed. One of the studios was taught by Gregg Pasquarelli, a partner in SHoP. The studio assignment was called “Bob and Jane Are Dead: Re-examining the Superblock.”  Bob refers to Robert Moses and Jane, as you might surmise, is Jane Jacobs, the two figures advocating opposite poles of 20th century urbanism. The first project immediately caught my eye. Titled “The Shroud and the Cloud,” the cloud represents the towers favored by Moses and the shroud is the contextual approach of Jacobs. The two students claim that either alone creates “architectural monotony.”

And so they set out to combine them in a “best of both worlds” approach that, strikes me as quite similar in concept to my proposal from almost 30 years ago: a street level urbanism Jane Jacobs might approve of with inventive and exciting new urban forms rising above it.

Which brings me back to sliver towers. They are generally attacked as uncontextual and unwanted intrusions, and both criticisms are usually accurate. But disallowing new construction and not providing needed new housing is not realistic. Except perhaps in the most significant of historic districts, it simply isn’t feasible to preserve neighborhoods in landmark stasis. Nor is it desirable. Cities cannot be stuck in their pasts as people, cultures and economies evolve. Even Paris, often cited as either the quintessential example of the ideal low-rise city or, conversely, as a tourist destination disguised as a city, is allowing high-rises.

So if new construction and increased density is inevitable, how can it be accomplished without sacrificing communities? And let’s go one better. How can it be designed to improve communities? We have a model at hand, and it involves using the often criticized “transfer of development rights” process to preserve the strong urban fabrics while allowing encouraging positive growth.

A friend of ours was approached a few years ago to sell his air rights to a developer putting together a mid-block high-rise a few doors away from his building. He held out as a matter of principal while his neighbors sold, and at the time we complimented him roundly. Now I’m not so sure I agree.

Yes, the building that resulted is architecturally heavy and, far from adding to the neighborhood, has become a nuisance in that it is a hotel with no connections to the community and its second floor rooftop parties can be hideously noisy. Indeed, a slightly earlier nearby high-rise hotel has exactly the same issues. (Who’d have thought we’d see glass tower high-end hotels in the Lower East Side?) But it doesn’t have to be that way.

What we can have, I’m suggesting, is what I term “towers in the block.” Much as the Yale students recently proposed, and as I proposed much earlier, we can modify the towers in the park idea to correct its faults and simultaneously incorporate the wisdom of contemporary post-Jacobs urbanism.

But how does this work in the (increasingly rare) case of whole-block construction? SHoP’s renderings for SPURA are basically towers in the block. But, glass tower esthetics aside, by proposing block long buildings, they fail to create a good base over which to put the towers. The street is, to use Pasquarelli’s students’ words, architecturally monotonous. Its nod to contemporary urbanism, beyond some gestures to amenities, is present only in the setbacks on the plinths. Look at any new building like this, whether nearby in the LES, uptown on Broadway on the Upper West Side, in downtown Brooklyn, or any number of other cities, and the street level is devoid of local character and mindless of community.

This is, I want to stress, at least in part an architectural problem. Though zoning may mandate ground-level commercial spaces and setbacks (and hopefully may start to regulate the proliferation of chain stores and big box retail), in the end zoning is not the same as design, and it is designers who have the potential – and the responsibility – to provide the architectural bones in which street vitality and community can grow.

Architects need to study (and force their clients to look at) the banality of most new urban buildings, the unfriendly and unrelenting monotony of their creations. The towers in the block concept provides two related models for moving beyond this, one for blocks with existing strong urban fabric and one for larger scale blank slate sites. The latter needs to be informed by, without directly copying, the former.  For the latter to work, it needs to look beyond the expedience of large scale uniformity and the architectural hubris of the megablock. It’s not that Bob and Jane are dead. The lessons of both are very much alive and need to be combined.
