BLDGBLOG: Some News and Abuses...

A few quick news items:
<1> BLDG|BLOG contributor Geoff Manaugh has joined the Archinect editorial team, a position he will be sure to abuse inappropriately.
<2> BLDG|BLOG contributors Nicola Twilley and Geoff Manaugh have co-written a piece for the upcoming "special issue" of Space & Culture. The issue itself is called "New Orleans and Other Urban Calamities," and their piece is "On Flexible Urbanism." Be sure to pick up a copy. In other words, be sure to read a copy.
<3> A new Russian utopia is being built and planned outside Moscow – to be inhabited only by millionaires: "Keeping up with the Jones's could take on a whole new meaning in a town being planned for rich Russians near Moscow," the BBC says.


[Image: "The $3bn (£1.7bn) town of Rublyovo-Arkhangelskoye"].

This new, semi-instant city "will house some 30,000 residents and is expected to be almost twice the size of Monaco. It will be completely self-sufficient, boasting luxurious villas, a clinic, bars, sports facilities, a school and a marina on the Moscow River." And if that sounds fun, you should read Super-Cannes.
<4> A "lost" map has resulted in approximately 1.5 million acres of the Arctic National Wildlife Refuge being opened up for oil exploration. You read that right; the foam core ate it. Ate the map, that is.
<5> Is the Chinese building boom a bubble? It depends how you define the word bubble... "China's real estate market is so hot that miniature cities are being created with artificial lakes, and the country's nouveau riche suddenly seem eager to put down as much as $5.3 million for a luxury apartment in skyscrapers with names like the Skyline Mansion..."

Hyperoxic architecture

In this week's New Yorker there is a short blurb about "Richard Wiese, the president of the Explorers Club," who is getting ready "to climb a pair of volcanoes in Mexico."
The real challenge, it seems, will be in preparing his body for substantial changes in altitude – and so Wiese has installed an altitude chamber back home, in the center of his office.
An altitude chamber? "The air inside simulates that which you would breathe high in the mountains: it contains less oxygen" – which prepares your body for the trip ahead. (There are, in fact, whole university training courses in this).
The chamber, in other words, is hypoxic.


[Image: David Blaine, in a transparent box over the Thames – totally irrelevant to this post, but it looks hypoxic, so...]

What's fascinating here, aside from the levels of metaphor at work – the president of a prestigious Club in New York City, whose office is "on the third floor of a Tudor-style mansion on the Upper East Side," steps into his own private atmosphere everyday, a rarefied chamber of unearthly reserve, at one remove from the polluted ruins of Manhattan outside, a man of Olympus, breathing only the best oxygen his money could buy, etc. – but the terrestrial implications.
The geographic implications of an altitude chamber.
Much has been made of the so-called "horizontal" networks in which we now supposedly exist – I can phone someone in Adelaide, for instance, or order machine parts to be fabricated in Guangdong; it's all part of advanced globalization.
But an altitude chamber raises the intellectual stakes: this is the vertical linking of different, unconnected levels of the earth's atmosphere. The altitude chamber, as The New Yorker says, "simulates" other vertical levels of the planet. Sitting inside of one, you could talk down to what the article calls "a sea-level visitor" even while resting high and mighty – at the exact same level of altitude.
One could, in fact, very easily imagine the next trend in restaurant design: rather than decorate with a Thai theme, or Japanese decor, a Roman ambience, you'd have a 15,000-foot foyer, or an exclusive, 22,500-foot back room. It would be the literal depressurization of the social environment.
Who cares if you can eat in a restaurant that feels like Paris? When you could eat at a restaurant that feels like it's at 65,000 feet?
But I think I would prefer a hyperoxic chamber, in fact, because the more oxygen the better. Unless I burst into flame. But I could sit there, behind glass walls, like Lance Armstrong or the Oracle at Delphi, making elliptical pronouncements on a steady flow of pure oxygen about the virtuality of altitude, the simulational abilities of air itself – and I could impart upon legions of sealevel dwellers this vision of a new city, circular, utopian, made entirely of hyperoxic architecture, Euclidian, cubic, cylindrical, gleaming glass like crystal in every wall, people breathing, breathing, a city of nothing but ageless people breathing.
And the sun would set over a world of pressurized geometry.

Structures of mass wasting

In an almost giddily good essay called "Los Angeles Against the Mountains," John McPhee describes how architecture can survive in the fallout paths of rock slides, debris slugs, and other flows of geologic mass wasting.


The scene? Southern California's San Gabriel Mountains – "divided by faults, defined by faults, and framed by them" – against which Los Angeles has grown, its outermost neighborhoods now encroaching upon what McPhee calls the "real-estate line of maximum advance."
"The San Gabriels are nearly twice as high as Mt. Katahdin or Mt. Washington, and are much closer to the sea. From base platform to summit, the San Gabriels are three thousand feet higher than the Rockies." Further, McPhee informs us, "in their state of tectonic youth, [the San Gabriels] are rising as rapidly as any range on earth... Shedding, spalling, self-destructing, they are disintegrating at a rate that is also among the fastest in the world."
Rising up, rising down – the San Gabriels produce, in the process, some of the most extraordinary rockslides ever documented: "On the average, about seven tons disappear from each acre each year – coming off the mountains and heading for town."
These slides are known as debris slugs, and they "amass in stream valleys and more or less resemble fresh concrete. They consist of water mixed with a good deal of solid material, most of which is above sand size. Some of it is Chevrolet size." Debris slugs have been known to contain "propane tanks, outbuildings, picnic tables, canyon live oaks, alders, sycamores, cottonwoods, a Lincoln Continental, an Oldsmobile, and countless boulders five feet thick."
And all of it comes crashing down – frequently going right through people's houses.


In the face of "this heaving violence of wet cement," new architectural techniques become urgently necessary – that is, architecture becomes as much a technique as it is a structure: "At least one family," for instance, "has experienced so many debris flows coming through their back yard that they long ago installed overhead doors in the rear end of their built-in garage. To guide the flows, they put deflection walls in their back yard. Now when the boulders come they open both ends of their garage, and the debris goes through to the street."
Deflection walls, overhead doors, feeder channels, concrete crib structures – the lived topography of dwelling shifts in the presence of geologic collapse, as if to mimic those inhuman tectonics.
And yet the shift's not limited to houses – the whole city's in on it.
Los Angeles county "began digging pits to catch debris," surrounding itself with voids to counteract the unleashed brawn of surprise geology. These debris pits are "quarries, in a sense, but exceedingly bizarre quarries, in that the rock [is] meant to come to them."
Strange attractors.
"Blocked at their downstream ends with earthfill or concrete constructions, they are also known as debris dams. With clean spillways and empty reservoirs, they stand ready to capture rivers of boulders – these deep dry craters, lying close to the properties they protect."


In all their concrete, neolithic abstraction – like great walls of pharaohs, embedded in the Los Angeles hills – these basins can be "ten times as large as the largest pyramid at Giza." Yet they are empty – vast concavities – ready to be filled in a single night's rush of silt. Attack of the debris slugs.
When so filled, in fact, these artificial mini-anti-quarries, so to speak, bearing nearly "four million tons of rock, gravel, and sand" in some of the deeper basins, become something of a highway-builder's wet dream: a "private operator," for example, "has set up a sand-and-gravel quarry," using exactly these reservoirs as rock mines. You can almost feel McPhee kicking himself for not thinking of it first...
In any case, the rockslide-ready house, complete with internal avalanche channels and overhead doors, offers us a new domestic typology: a house that also serves as a valve for natural processes.
Several variations ensue: you could build a house on a migration route for international waterfowl. It should be a very, very large house. The international waterfowl should be very, very stubborn. They will not change course. They are committed, and your house is in the way.
Every March, therefore, a ritual begins: you roll up your garage doors, you slide open the glass back living room walls, you throw plastic tarping over all of your most expensive furniture – and then, all afternoon, massive flocks of waterfowl come arcing straight through. Temporary house inhabitants. Clouds of them. Soon you charge admission, and at $5 a head you're a millionaire: people come from all over the world to sit inside your house, in specially placed chairs, and just watch migrating birds fly through.
Etc.
So as debris slugs continue to scour their way down out of the San Gabriel Mountains, reclaiming the terrain of peripheral Los Angeles, perhaps Californian houses can learn to open up: pop open a door here, a window there, perhaps attach some chutes and kiddy slides between them, all ramps and moving surfaces, and you've got a valve house, flexibility vs. natural collapse. A kind of earth-fountain.
The spectacle of mass wasting begins: sand, pebbles, rocks, boulders, Oldsmobiles, canyon live oaks, migratory birds – everything nature's got, whirling through your house in a geotechnical storm...
But there you are – with the architecture at the center of it – sitting ready, open to the world, tectonic.

City Idols

The urban coats of arms made me think of the amazing city models that are to some extent the antithesis to the postage stamp icon.
Dubrovnik probably has the most intimate relationship with their city model. Throughout the gates, one finds sculptures of their bishop holding the model of the city – a reference to the complete reconstruction of the city after a 1667 earthquake.


Similarly, Berlin houses an enormous model of the present day city, as well as a replica of the Soviet plans that were only partially built.



I believe the largest of the these city models is of Shanghai.


Koolhaas talks about the 1845 model of New York as an act of self-idolatry – both possessive and communicative. Unlike the icon, the model is aspirational.

Bigsexyland

"As the World Cup approaches," we read in The Economist, "Berlin's businesses are positioning themselves for best advantage. The latest manifestation of this trend is a new, luxury mega-brothel, which opened in late September, just three train stops away from the Olympic Stadium, the tournament's main venue."


[Image: The interior of the Artemis, Berlin; from Der Spiegel].

"With plush red curtains," Der Spiegel writes, "leopard-print cushions and more gold than you'd find at Posh and Beck's wedding," the so-called Artemis boasts €5 million worth of refurbishments, including "saunas, jacuzzis, cinemas and a swimming pool, complete with the requisite mini-tropical island. Leopard skin textiles and strategically-placed mirrors abound" – transforming the brothel into a kind of sexualized Sir John Soane's museum.
Further, the Artemis "can cater for up to 100 prostitutes and 650 male clients. The women are not actually employed: along with the men, they pay a €70 entrance fee and then keep the money they earn," says The Economist.
But what if there are women clients? And would male sex workers be able to "employ themselves" there, as well? Or will the building financially reinforce expected sex roles?


[Image: The Artemis; from Der Spiegel].

According to Norman Jacob, lawyer for the Artemis (and he says this with apparent sincerity): "[Any female sex worker] can go into the sauna or the swimming pool, get food and non-alcoholic drinks for free. She can even spend the night here and just sleep. And if she has sex she earns money."
I suppose this is considered a good deal.
But what about the architecture?
As Der Spiegel writes, "the outside of the building is about as erotic as a corporate office park, the interior is a bizarre cross between mid-1990s Las Vegas and a cheezy British 'Carry-On' film. The historical decorative flourishes, presumably designed to give the place a touch of class, are almost overwhelming: Greek and Roman statues nestle under Moorish arches, pseudo art deco frescos adorn the walls and even the odd Chinese character on black lacquer is thrown in for good measure. Pretty much every era which has ever been deemed erotic is represented."
Or, eroticism as a function of architectural ornamentation.
Adolf Loos must be spinning in his grave (or perhaps he's just humping the coffin...).

Roadhenge


A short essay in the new issue of Architectural Record (October 2005) introduces us to Charles Ross's Star Axis, a geo-architectural earth-installation in the New Mexican desert.


Using "stone forms that spring directly from planetary and stellar geometry," Ross has aligned Star Axis, Stonehenge-like, with the larger, macrocosmic movements of space.


As Ross himself says: "Star Axis is an architectonic earth/star sculpture," consisting entirely of "earth-to-star alignments built to human scale."


"Ross has been building Star Axis bit by granite bit, conducting aerial surveys, topographic mapping, and astronomical calculations to align its features with the cosmos."


The complex consists of an Equatorial Chamber, a Star Tunnel, and a Solar Pyramid. "The angles of its Solar Pyramid," for instance, "were determined by the sun's position during the summer and winter solstices."
Elsewhere, "[g]ranite buttresses 6 feet thick and 52 feet high enclose a horseshoe-shaped entry area" that "took more than 10 years to carve." (10 years! He should have used the Jardinator).


But I'm reminded here of a drive I find myself on quite frequently: at one point I have to turn right, at an intersection with a stone church, near a school and some tennis courts, to get onto a long, flat road – and there, in the distance, blinking red in the clouds, always, are a tall series of suburban radio towers, like timed constellations turning on and off every night over the peripheral hills. Radio supercluster.
Then, however, further on, there's another road that, every spring, has the moon rising over it – you're driving over a bridge when you see it; then yet another road with Orion clear and hovering above it in the winter (or so I tell myself); etc.
And it occurred to me, then, that a whole city could serve as a kind of accidental astronomical device – Star Axis on the metropolitan scale – a space-measurement machine, made of solstices and full moons and boulevards; and that perhaps a fortuitous coincidence of urban design and high-rise architecture – and exurban motorways and backroads and well-timed traffic lights – could all add up to produce an analogue of the heavens here, now, in the form of a city.
As above, so below.


Roadhenge.
The roads themselves, in other words, would follow and frame constellational events in the sky. At the end of every street – if you could see past the Dunkin' Donuts franchises and the endless car parks and the redundant, publicly-funded football stadiums that sit there in the off-season, empty, like expensive bowls of air – there, perfectly aligned above the abstract symmetries of concrete and tarmac, are the stars of Gemini, or the blinking double-lights of Algol, or Orion's belt playing hide and seek in an arc behind the Barbican.
Or there's a truck in the way, but no mind: the roads of the city, in different seasons, correspond to different stars and routes of precession. Take the Great Northern Road to see Jupiter in March; take Western Ave to see the moon rise in October; use the car park at Charles Ross/Star Axis Memorial Hospital for a view of the solar eclipse.
Urban design as a function of astronomy.
There could be a road that everyone drives once a year, or a footpath, that perfectly frames the changing constellations above – but only on the night of the summer solstice. Guidebooks could be produced; people could come from all over the country; when you're in a bad mood you could walk the path the wrong way...
You could even deliberately seek out all those streets in the city that have no superlunary correspondence at all, that map to no stars, that refer to no constellations, refusing to emulate the ways of heaven.
Which actually raises the quite interesting possibility that an entire city could be built, zoned, and constructed to the precise heights and locations necessary to block all views of the cosmos. You'd never even know the stars existed. And this could happen accidentally, over time, with no one planning it or expecting it to happen; you take a new job, and move to a new city, and one night you go out for a walk only to realize, my god, you can't see a single fucking star...
The buildings perfectly blot out the sky...
Anti-Star-Axis City.

Evacuating Manhattan

On September 11th, 2005, Sam Roberts of The New York Times found himself wondering aloud how mighty island Manhattan could be evacuated in case of emergency.
"Today," he writes, "four years after the Sept. 11th, 2001, attacks and in the wake of Hurricane Katrina, there is still no single plan to evacuate all of New York, which virtually no one believes is possible."


No one?
Could this be it, then? The greatest opportunity of all time for an ambitious urban performance artist? To evacuate Manhattan? Leaving behind an unpopulated void of steaming sewer lines, windswept avenues? The entire archipelago reduced to silence, almost instantly prehistoric; birds soar in the self-reflecting absence between bank towers.
Forget David Blaine and his stupid transparent box over the Thames


– you've just made 8 million people go to Weehawken.
So what would evacuating Manhattan actually look like? "'It would not be easy and it would not be pretty,' said Jerome M. Hauer, the city's former emergency management director."
Accordingly, we're told to "imagine trying to move more than eight million New Yorkers – including the high number of people without cars – through streets that are clogged on an ordinary day and then through the tunnels and over the bridges that connect New York's islands to the mainland and to one another."
OK – but as Houston just proved, private car owners do not make large-scale evacuations any easier. In fact, leaving such evacuations to the private sphere – that is, to people who own and maintain private automobiles – is illogical from the very beginning.


[Image: Private automobile owners fleeing Hurricane Rita – now imagine them all trying to merge into Lincoln Tunnel].

Even so, the evacuation of Manhattan has been simulated for decades.
"[A]fter a test-run," for instance, using "a flotilla of 20 ferries, barges and tugboats up the East River in 1951, officials figured [that] 100,000 [people] an hour could be spirited away for six hours; [but] then the flow 'would taper off for lack of equipment'" – leaving everyone else to fend for themselves. (It is worth adding the obvious here: the population of Manhattan has grown substantially since 1951 – 600,000 people would hardly even be noticed).
Sensing disaster, someone soon proposed that the city could build "two cross-town expressways to speed the escape from Manhattan" – or, urban space as advance imprint of impending catastrophe.
Still, evacuating Manhattan "would be fraught with nightmarish challenges, like rescuing people from hospitals and nursing homes and reversing traffic flows. 'It's a matter of where you put all those people when you get them out of Manhattan,' [Jerome M. Hauer] said." (Have they considered Brooklyn?)
It is interesting, sarcasm aside, to consider what new feats of urban design could preemptively account for this future, inevitable evacuation of the iron island. A series of pedestrian bridges to New Jersey, perhaps? Or some helipads? Tax breaks for evacuation taxi drivers? Pedestrian tunnels, leading to Queens, Brooklyn, New Jersey, and even Staten Island?
A light rail? More boats?
Perhaps the entirety of the Lower East Side could literally stand up – buildings and all – and just walk away?

The skin of Chinese prisoners

According to the The Guardian, a "Chinese cosmetics company is using skin harvested from the corpses of executed convicts to develop beauty products for sale in Europe."
And, no, that has nothing to do with architecture.
(Unless they start producing wallpaper...)

New maps of national absence

As per the architectural averages of Meggan Gould, Jason Salavon, self-styled photographic king of the averaged image, has declared war on the US housing market through a really almost awe-inspiring photographic series called "Homes for Sale."
By taking the visual average of, for instance, 114 homes for sale in the Dallas/Ft. Worth area –


[Image: 114 Homes for Sale, Dallas/Ft. Worth Metroplex].

– Salavon really just obliterates any claim to individuality – let alone architectural interest – that the (literally) average American home now has.
The housing market, in other words, has broken.


[Image: 124 Homes for Sale, The 5 Boroughs].


[Image: 117 Homes for Sale, Chicagoland].

How do you even know where you are? New York? Chicago?
St. Louis?
What's so exciting about these images is how sarcastically condemnatory, rigorously critical, and yet strangely beautiful they really are. Of course the promising landscape of "America" is being destroyed by its own architecture; of course that country is falling victim to bad – or utterly absent – planning.
But Salavon's images make this visually obvious, graphically accessible; they take what every American sees, everyday – driving through the exurbs, living in the midst of the homogeneous – and these images give it an iconography.
They represent the total mediocrity of America's anarchitectural establishment.
Everyone's houses look the same.


[Image: 121 Homes for Sale, LA/Orange County].


[Image: 112 Homes for Sale, Miami-Dade County].

Do you live in LA, or do you live in Miami? How the fuck can you even tell?
The symmetry and abstraction is by now so complete that America could fold in on itself through some complicated topological procedure, coast to coast, heartland to homeland, LA to Miami... and it could utterly disappear.

Toward the end of Mark Rothko's life, as he drifted closer and closer to an unavoidable suicide, the paintings he produced grew more and more monochrome, lunar, enveloped in black and white, monumental, voidlike, immense.


[Image: Mark Rothko, Untitled, 1969].

As the color and vibrancy and detail and expressive individualism – even the ironic beauty – of the American housing market continues to flatline, it will be interesting to see if, in several years' time, as the decades turn, as the millennium ages, perhaps Jason Salavon can return to this series and produce more maps of the architectural void, the evening-out, the swan song, the facade of national absence, to see if the architecture of an entire nation has succeeded in committing suicide.


[Image: Mark Rothko, Untitled (No. 4), 1964].

Until then, millions and millions of American homes will continue to be for sale.

Graphite cathedral

With thanks to the illustrious Jim Webb, we learn that Dalton Ghetti has carved a church – out of the graphite inside a pencil. While it was still inside the pencil:


But how about an entire city? Graphite urbanism. Leadville. Pencilicity.
Or – a pencil. Carved out the graphite inside a pencil.

Foodscaping

Akiko Ida and Pierre Javelle (a French pastry chef/arts photography team) create landscapes out of food: mushrooms, kiwis, salads, ice cream, watermelons, cakes. Cauliflower, even.
The result is actually really funny and great, and can be seen through the duo's own photographs:


[Image: Week-end].

Gastronomic landscapes, or gastronomescapism, perhaps.
For those curious, of course, there's more to be read at the Galerie Fraîch'Attitude (in French); and, if you have a lot of patience and a high tolerance for slow and completely unnecessary Flash, then you can visit their own website for some more images – some really, really great images – making all the frustrating Flash b.s. almost worthwhile.

The mining industry


[Image: P.R.S. Gallery].

In his unfortunately titled but excellent book Encounters with the Archdruid, John McPhee receives, from mining industry consultant Charles Park, a crash course in exploration geology (there's "the rootlessness of the life of an exploration geologist... 'You're just wandering. You're on the loose'"), as well as a quick introduction to the modern process of gold mining – which sounds a lot like medieval alchemy:
"The rock, Park explained, is taken to the surface and crushed until it is fine sand. Mercury is poured through the sand. The mercury adroitly picks up gold, and nothing else. The mercury is then boiled away. Cyanide is poured into the sand and dissolves from it even more gold. Zinc is then put into the gold-cyanide solution. The zinc dissolves, and replaces the gold, which falls as metal to the bottom. The sand is put back in the mine, where concrete is poured on it to make platforms for upward mining. Thus, the mine consumes its own tailings" – in a perfect architectural-alchemical loop that owes much to Ouroboros, the self-devouring, occult world serpent:


A few quick questions, then – because this is not a website about alchemy or the occult – or even about Ouroboros – it's a website about architecture, dammit:
If alchemy is considered a "religion" – and not just a form of speculative metallurgy – when America's gold mining industry receives federal tax subsidies, does that violate the separation of church and state?
Accordingly, are exploration geologists really Earth-worshipping pagans in an alchemical conspiracy against the U.S. Constitution?
Should somebody warn President Bush...?

Urban coats of arms

How do you represent a city?


What decisions would you make – graphically, textually, even musically – in order to produce something sufficiently emblematic of an urban experience, something people all over the world could recognize and relate to?


[Image: Need a hint? Think Oprah].

If you had to represent New York, for instance – or London, or Shanghai, or New Orleans – or Atlantis, for that matter – what, first of all, does such a question even mean? How do you "represent" "Shanghai"?
"You."
Well, let's just say that we've answered those questions: what, then, would you choose? The people? The landscape? The skyline?
The architecture?

A series of digital city guides, produced by The Economist, uses unique graphic emblems to represent each city under discussion – in the process, making clear artistic decisions about what does or does not constitute "London" or "Sydney" or "Tokyo."
Overwhelmingly (if unsurprisingly), these graphics – like urban coats of arms for the 21st century – choose landmark architectural sites and streetscapes for their centerpiece.
From the obvious –



– to the slightly less obvious –




(why obscure Berlin's TV tower in clouds? why not include the Reichstag? and is that really the best Brandenburg Gate they could draw?)


(here, why hide the Golden Gate Bridge to focus on a cable car – which, as drawn, looks like every other tram on earth?)

– to the downright ugly –


(that's Tokyo!)


(Dubai!)


(is that a UFO invading New York? why not a flaming World Trade Center?)

– to the surreal or overly abstract:



Those last two? Mexico City and Toronto.
Bilbao, Rome, Rio, Las Vegas, Montreal, Marrakech, Cairo, Baghdad – all emblemizable, so to speak: but what would those emblems depict? And what of so-called minor cities, from Glasgow to Winnipeg, Frankfurt to Xian?
What about The City of Lost Children?
What about Guantanamo Bay?
If we were to develop a new series of international coats of arms for all our global cities, what buildings or spaces or skylines – or bodies of water, or atmospheric events, or exposed geological formations, or even emblematic animals or famous disasters – earthquakes, fires, floods, terrorist attacks, atom bombs – would be included?
How do you represent a city?
