For PlanPhilly
In Philadelphia, the uneasy alliance between new and old buildings occasionally flares into combat. The resulting skirmish, says architect and historian Steven Semes, almost always sacrifices cohesiveness to individuality. Whether this occurs via a modern addition glommed onto a historic building, or through the insertion of a modern building into a traditional streetscape, dissonance ensues.
Looking around town, we see evidence of the ways in which this happens.

The new Robert A.M. Stern skyscraper, 10 Rittenhouse, for example, attempts to borrow elements from its older neighbor, but soon goes its own way to a quite obvious (and soaring) departure. Placed on a tight, though vibrant, side street off of Rittenhouse Square, the building's height clearly individualizes it from its neighbor. In the end, it doesn't make much of an attempt to fit in.
The idea of homage reaches ironic abstraction in Robert Venturi's and John Rauch's "Ghost Structure," which playfully takes the form of the kind of building that Ben Franklin might have lived in, and then reduces it to a mere sketch. "Venturi is a great mind, but I think this is a joke," Semes told PlanPhilly in an interview prior to his lecture March 9 at The Athenaeum.

"We learn nothing from this frame, and we would have if the building was totally reconstructed."
The violent 'facadectomy', like the one currently in progress on the 1600 block of Locust St., as Curtis Institute of Music readies itself for an expansion, also gives a nodding glance to the idea of incorporating the old. But, says Semes, ultimately what goes on beyond and behind such a facade contains no reference to that past.

"What's happened to the landmark? It's as if the intent is to grudgingly save it while pretty much cutting it off," Semes says.
And then there's the real slap in the face — bracing to many, reason for a duel to others — of projects like the one now under consideration for the Keystone National Bank building. That "intervention," while promising to restore much of the building to its former glory, stops short of a total re-creation. Instead, it proposes erecting a new glass entryway to replace the horrid storefront slapped on in the '60s.

Thirty years from now, will this new entrance look dated, garish, misguided? Probably.
None of these approaches can ever truly succeed, believes Semes, because the differences between classic and contemporary architecture are "fundamentally irreconcilable," he writes in his new book, The Future of the Past (W.W. Norton).
"There are ways to make something modern," he told PlanPhilly. "But what I'm questioning is the idea that you have to compose something that's deliberately jarring. What we should be thinking of instead is: 'how do we work within the historic setting?'"
In his advocacy of what he calls the "appropriate," his pursuit of the intact "ensemble," and his call for the avoidance of the "incongruous," Semes urges us to consider contexts. "The idea that the building exists as a kind of entity takes an extremely narrow view of what the building means," he says. 
"The Cira Centre, for example, would be a lovely object if it was three-inches tall and sitting on a tabletop like some sort of Swarovski candlestick," he continues. "Unfortunately, it's a 30-story office building that looms over everything in a very menacing way. If you think that your job is to fit seamlessly into the context, you'll have one result. If your primary object is to make sure the first thing that's noticed is your project, then you'll get a different result."
Traditional cities are ones whose buildings contribute to the whole, Semes elaborates, whereas contemporary downtowns are more like zoos. "There's the Gehry here, the Hadid there, the Nouvel over there," he says. "And they all have to be kept apart — they have nothing to do with each other."
Borrowing one idea from the zoo, and national parks and public gardens and the like, though, might make a good idea, Semes suggests. That's the notion of "conservation,' a central theme of his book. "If you have a wetland or a battleground, you don't interfere with it," he says. "You try to cultivate it and keep the ecosystem alive and intact. There's an ideal of healing and caring for a historic setting that makes a lot of sense."
Just as we wouldn't tolerate a big box store being introduced into such a setting, we should think more carefully about affixing jarring interventions to old buildings — like the glass "gaskets" that are used so prominently these days to link old sections with new additions — and about incorporating modern buildings into historic streetscapes, Semes says.
"While there ought always to be room in our cities for architectural innovation and experimentation, there must also be places dedicated to the continuity of valued architectural character," he writes. "Keeping these two desiderata in balance is the challenge now faced by architects and preservationists alike."
Of course, there is a tactic that makes the challenge easier: total reconstruction. It's the Graff House (where Thomas Jefferson lived as he drafted the Declaration of Independence) vs. the Ghost Structure. "There's no question that some people find the act of reconstruction a diminishing of the surrounding historic structures," Semes says. "But if you look at that argument closely, it begins to unravel. The history of architecture is filled with buildings that are copies. The Parthenon is a copy, as is almost all of the Louvre that we see today, and temples in Japan. 
Steven Semes
"These tell us that what's important isn't the building itself," he continues. "What's important — assuming the re-creation is meticulous — is a sense of the ongoing culture." In his book, Semes singles out Philly's controversial Richardson Dilworth House, as a prime example. The 1957 building, while not a reconstruction, "contributes to the beauty and coherence of the Society Hill Historic District," he writes. "[Yet] it was seen as having little or no architectural value because its late Colonial Revival style ran counter to the authorized narrative of Philadelphia's architectural history."
In other words, the house doesn't jive with our notions of mid-20th-century architecture, so we don't value it. But even though the Dilworth House isn't "authentic," it is "appropriate" because it fits into its greater surroundings, giving precedence to the idea of the ensemble, Semes argues.
As we look around at Philadelphia — old new, and about-to-come — the takeaway is clear. "Cities are living organisms," Semes says, "and so of course not everything has to be traditional. But I think that having pre-conceived notions of contemporary architecture — whether it's as a glass box or as a blob molded from some new material — isn't the right approach, either. If the architecture of our time is whatever Renzo Piano or Steven Holl says it is, I don't see that the rest of us are obligated to go along."

Comments
This was an excellent article and a refreshing take on the woefully ineffective juxtaposition of modern and historic architecture that has crept up in certain areas of Philadelphia. I don't believe, as one other writer above stated, that this is an attack on the mix of architectural styles that naturally develops in a city over time. Rather, I think it draws attention to attempts at integrating modern buildings with the historic fabric that fall flat on their face. These inevitably seem to involve some architect claiming an abstract relationship between two buildings--bricks that will remind us of a historic structure, or an entryway reminiscent of an older style--that in reality aren't apparent to anyone looking at the building and do nothing to mask the fact that the new structure is in complete contrast to its neighbor. The photo of "Ghost Structure" above, or the debate over the President's House on nearby Independence Mall, are perfect examples of the failure of this type of architecture where faithful reconstructions of historic styles would have been more appropriate. When working with historic buildings or historic sites, Semes is correct in calling for an approach to design that does not insist on contemporary architecture as the only option while deriding serious attempts at imitating historic styles.
I find many flaws in this article, and responding to each of them would take much too long, so I'll just focus on one. While people may not like the aesthetic of the "Ghost Structure" by Robert Venturi, it was and continues to be a innovative and iconic approach to historical architecture. Saying that a faithful reconstruction of Ben Franklin's house is necessary is really showing how little one knows about the Franklin house. There simply is not enough information known about the house to provide a realistic and accurate reconstruction, so trying to reconstruct it would only be misleading visitors by presenting them with a "factual" experience that is really just a collection of guesses and assumptions. By creating an abstract representation, Venturi was marking the place as historically significant, without making wild guesses at paint color and door trim. There are other outlets for this kind of information, and in fact the National Park Service owns and operates a building just steps from the ghost structure (the building that housed Franklin's printing business) that contains the artifacts and reconstructions that visitors may be looking for.
Ultimately, I understand that this is a historical city, but what is considered historical now was considered contemporary when it was constructed, and in order for the history of the city to grow, we have to continue creating architecture that is contemporary. Historic preservation plays a role in that overall view of the city's built history, but when something is lost, there's no need to reconstruct it. Adding another layer in the style of the times, as Venturi did with the ghost structure, is a perfectly acceptable way to acknowledge and respect architectural history and simultaneously create more.

Brilliantly said!
I must clarify for readers of this article that my comments which were quoted, either from my telephone conversation with the author or from passages in my book, were intended as general observations and were not intended as criticisms of individual buildings in Philadelphia. I have not yet seen the Robert A. M. Stern building near Rittenhouse Square, and so my comments were not about that building, nor the building by Venturi and Scott Brown on Locust for the Curtis Institute expansion. My interest is in how architects and lay people think about new architecture in historic settings and my book outlines a series of perspectives on this issue. I am not opposed to diversity and variety in cities, but when valued historic sites or districts are involved, it is reasonable to expect that respect for the pre-existing conditions might outweigh considerations that would otherwise be prominent in an architect's thinking. In the same way, conserving natural resources (a wetland or a rain forest, for example) might impose restricitons on what we build nearby. I hope that the issues raised here will get Philadelphians (and people everywhere) to talk more openly about what they think our obligations to historic places are and how best to fulfill them.
I think my issue is that Philadelphia - historic as it may be - has always functioned as a working city and as a result, has no inherently true "historic districts". Center City's one seemingly historic district is the result of a mid-century attempt to reconstruct a Colonial past, one which is only as important as a number of other movements responsible for the PSFS Building, the Divine Lorraine, even the Cira Centre. The result, Society Hill's "historic district", is a collage of questionable reconstructions which sacrificed dozens of 18th and 19th century buildings, some by Willis Hale and Frank Furness. This attempt at architectural cohesiveness created a very peaceful, historic illusion, but compared to the rest of Center City is one of the less interesting neighborhoods to look at. My point is that while historic districts are important, it is just as important to respect the existing history of a neighborhood which has naturally evolved. The Keystone National Bank Building is a prime example. Is it more historically respectful to replicate the original facade which was replaced less than ten years after it was constructed, or do you pay homage the the five successive facades implemented over the following 100 years by designing something truley modern that represents the needs of the existing urban fabric of a culturally, historically, and architecturally diverse neighborhood? Unfortunately we usually fall somewhere in the middle, attempting to appease the devout advocates as well as the needs of the client, and we end up with bland, historic interpretations rather than replacing the avante garde masterpieces we continue to lose with exciting, new architecture. Any empty construction site or blank facade has the potential to be architecturally significant someday. In a city as aesthetically diverse as Philadelphia, architects should be creating tomorrow's history instead of recreating yesterday's.
With that said, I am looking forward to reading your book. And you should know that Philadelphians are very passionate about our unique architectural history - obviously.
This is a terrible article. Seemingly attacking anything over ten stories for being tall and threatening, and also the facadectomy. The question is, what were the other options? We cannot turn back tthe clock and make these old buildings new again, its too expensive, and besides, there is no one offering to do that. Here in the real world we take what we are offered, or we say no and get nothing. Sometimes nothing is preferred, but not always, and not in the cases presented above. Could the Stern building be better? Yes. However, if it was the worstthing which had been created in CC during the last boom, we would be fortunate. At street level the building is engaging, the facadectomy on the Philadelphia Club works brilliantly, and the materials match the van Rensselaer mansion on the corner. In short, STOP HATING. Cities evolve, we are lucky to live in such a wonderful one.
I couldn't disagree more. What I find so aesthetically appealing about Philadelphia is the juxtaposition of architecture, good and ugly, old and new. Yes, cities are more than just the sum of their buildings and it is important that architecture contribute to the whole, but Philadelphia is a beautiful example of how this jarring mix of periods, heights, and styles result in an unintended, ecclectic cohesiveness that is far more interesting to look at than Boston or DC. In fact, I think our increasingly conservative attitude towards architecture has led to the unimpressively dull additions such as 10 Rittenhouse and Symphony House, attempting to recreate or pay tribute to some Colonial ideal that we never once actually embraced. Philadelphia has always been a melting pot of architecture, and that has allowed us to embrace and find value in many styles often considered dated by other cities, and to this day as managed to foster and attract some of the most creative artchitecture minds in the world.
