BIG’s design for Two World Trade Centre came online June 9 on WIRED, cascading onto YIMBY, Dezeen etc. Comments were mostly negative, clustering around the “universally reviled” end of the scale. I’m unsure why. At least it’s not a humungous number 2.
Those BIG people certainly keep the stories coming, don’t they?! I wondered what it would be this time. Vernacular 3.0? Hedonistic Placemaking? Turns out there’s no great idea, just a whole chocolate box of narratives that fail to synergise into an air of inevitable appropriateness.
The first thing that strikes me as odd is the huge disparity between the combined volume and density of the various narratives. Something’s being overstretched. Never in the history of architecture has there been a building with a different narrative for each corner and surface of its shape. The elephant in the room of course is volume that that shape defines, but let’s start with the corners and work our way around.
The south-west corner of the building is presented as a major design feature. It’s not much to hang a building off of, especially when it’s being called upon to represent an appropriate dignity, solemnity and respect at the same time. It’s too much to expect of something that is, after all, just a vertical corner.
BIG are masters at generating reasons that, though not lies, are red herrings. This corner is presented as the z-axis that generates an angled setback at ground level the setback angle is determined by its vertex and, since sunlight is involved, that vertex happens to determine a vertical line all the way up. A wedge is a wedge, not a triangle.
The performance condition of (symbolically laden) light penetration is thus responsible for the vertical line and not the result of it. What’s happening is that a mandatory performance criteria is being presented as clever aesthetic decision.
That single vertical links between vertical buildings on one side of the site and stepped ones on the other, “stitching two different neighbourhoods together.” Below, the image on the left is a collaged composite illustrating an assumed diversity? We’re led to believe different tenants occupy different buildings. The middle image illustrates the return-on-investment performance we associate with “boring” corporate buildings? The two good things of natural diversity and efficient enclosure of space have been reduced to aesthetic choices before being stitched together and reduced to an architectural proposition in the image on the right.
There’s some additional slight-of-media at work in these following quotes from the video release.
“The completion of the World Trade Center will finally restore the majestic skyline of Manhattan and unite the streetscapes of Tribeca with the towers downtown,” said Ingels in a video explaining the project.
This will create a visual link between the old and new districts where “the heritage city blocks of Tribeca meet the vertical towers of the World Trade Center,” Ingels added.
I don’t know who’s actually wanting the streetscapes of Tribeca united with the towers downtown, or a visual link between old and new districts. I’m wary of this sudden importance of Tribeca. My gut feeling is we’re being made to look the other way while something shifty happens elsewhere.
“From Tribeca, it will appear like a vertical village of singular buildings each tailored to their individual activities stacked on top of each other, forming parks and plazas in the sky.”
I’m also not comfortable with having to place so much trust in that vision – especially since the vision of a vertical village of singular buildings each tailored to their individual “activities” is a fiction we’re being led to believe. Two World Trade Center is not going to be let “box” by “box”.
The southeast corner is the stepped one on the right in the image below.
We’re told this stepped outline is generated by the volumes allocated to the seven different volumes that allow for different types of tenant.
I’m not buying this either. Even if there were seven tenants for seven boxes, would they really have different length-to-breadth preferences for their office space floor plates? Can seven different tenants for premium Manhattan office space at this location even be regarded as diverse? Again, a false performance criteria is being claimed as the justification for the decision to step the building on the east side and overhang it on the north. A dubious diversity is being replaced by the representation of a diversity.
The project’s redesign was warranted since financial firms had since migrated away from the Financial District, making leasing out the new buildings a struggle and further prolonging the World Trade Center’s redevelopment.
The fiction of the diversity narrative is proved in this quote from Curbed NY.
Half the 80-storey building (40 stories or at least three differently-sized usage blocks) is to be allocated to a single tenant.
And so we come to the south-east corner.
“Two World Trade is almost like a vertical village of bespoke buildings within the building, that also can be seen as a single tower. It actually has an inclination towards One World Trade Center, so the two towers — even though they’re not twinning — by having a mutual relationship, the space between them is parallel, although at an incline.”[WIRED]
Parallel lines are contained in parallel planes and the only parallel plane of One World Trade Center is the isosceles triangle of the east façade. The parallel line is its southern edge. It’s shown correctly here.
It’s this red line.
The “mutual relationship” magicked by this effect will be apparent from anywhere those two lines can be seen simultaneously, but preferably against the sky. This means a maximum view angle of 225° determined by the facade angles in plan of One World Trade Center. From this, we must subtract those 90° which the “diagonal” of 2WTC can’t be seen, as well as the angle for which 2WTC obscures 1WTC. I think too much is being made of an effect that at best can only be seen from 125° out of 360°.
The effect is strongest from here,
not so apparent here,
oddly imperceptible here,
and obscured here
It ought to be strongest between the two buildings but it’s hard to tell. The right edge of the reflected triangle in the image below is the important one but if the effect is underwhelming in a publicity image then it doesn’t bode well for the reality. Perhaps we’re just being trained to see it. After all, we have to imagine this fantastic diagonal anyway.
When done right, the parallel diagonal effect is strong and compelling. The only other time I’ve seen it is the 2009 Sama Tower in Dubai. Its west facade is a partial isosceles triangle and its east facade an inverted one – making diagonally opposite corners parallel. Seen against the sky and especially from a distance, we perceive those corners more strongly than those not seen against the sky.
Sama Tower works this effect across a mass but Two World Trade Centre sets it up with One World Trade Centre across a void. Whether there’s any poetry to be found in this I don’t know. What I do know is that to take One World Trade Center and appropriate it into a new visual composition involving a notion of “twinning” is a highly intrusive thing to do. But why even bother to draw our attention to an effect so weak and partial? I’d appreciate it more as a happy coincidence.
We’re reassured the footprint is the maximum permissible. Whew! In the diagram below, the red rectangle at the top is what’s left after various vertical setbacks are applied to the extruded footprint. It doesn’t tell us much other than that an infinite number of volumetric arrangements are possible. Why this one?
I’ll update this when I have more information on setbacks. An environmental impact assessment hasn’t yet been filed with the New York City Department of City Planning.
For now, the setbacks and overhangs are new surfaces created by this stepping of blocks and they too can’t be left unjustified.
Trees are good. There’s nothing to say except “Why?”, “Why not?”, “Why now?”
There’s also some newly created undersides in need of a story. “Hey, anybody got a story for those undersides yet?” “Høld it – I’ve just had an idea! Let’s have News Corp headlines tickering over them!” News Corp headlines eh? Have you already imagined it? I have.
BIG’s team seem to have kept the same viz. people for the money shot but someone may have insisted upon this to continue the deception it’s all about looks.
The angle and foreshortening, by the way, are legit if you’re an X50 telephoto lens positioned midway along Port Jersey Boulevard.
As of 23/06/2015, the Two World Trade Centre Wikipedia page stated as follows:
200 Greenwich Street (Foster+Partners): The total floor space of was anticipated to include 2,400,000 square feet (220,000 sq.m) of office space and another 130,000 sq.ft (12,000 sq.m) for retail shops and access areas to the underground World Trade Centre station. That’s a total of 2,530,000 sq.ft (235,000 sq.m).
Two World Trade Centre (BIG): The first three floors of the 2,800,000 sq.ft (260,000 sq.m) office building, including the ground level, will feature about 100,000 sq.ft (9,300 sq.m) of retail space. That’s a total of 2,900,000 sq.ft (270,000 sq.m).
That’s a 35,000 sq.ft (3,251 sq.m) difference or, to put it in terms a property developer can understand, the BIG proposal provides 14% more leasable space!
F+P’s website claims an area of 290,000 sq.m but gives no breakdown. On the other hand, it must be mentioned that Two World Trade Centre’s Wikipedia page has been revised five times a day since “19:38, 9 June 2015 220.127.116.11 (talk) . . (22,748 bytes) (+480) . . (undo)”. A few more revisions might be in order.
Here, Ingels speculates that the sky lobby in the F+P design “may have contributed to the old design not getting built”. Wikipedia presents this speculation as fact.
Financial firms were the intended occupants for Foster and Partners’ 2 World Trade Center, and the original proposal’s sky lobby design was not attractive to media tenants, who have been the leading tenants of the new WTC towers and are now expected to occupy BIG’s redesigned building.
Changing elevators is a bore for anyone, regardless of what type of company they work in. Not having a sky lobby would make the upper half of the building more attractive to any office tenant. Large and regularly shaped floor plates would also be attractive to any office tenant.
Instead of being seen as a design feature people were already attuned to by the masterplan,
the diamond-shaped features of the Foster+Partners design are now being presented as cramping floor plate performance. What a difference 15 years makes! Property development is like Nature in abhorring a vacuum, relentlessly working to fill empty spaces.
It must be said, F+P do have a history of highly contrived and inefficient floor plates.
We’re told the client wanted a bank-like building when it looked like one would attract a bank tenant, but changed their mind when they saw nearby buildings filling up with media types. It’s true that F+P designed 200 Greenwich as a bank building. There’s a mammoth trading floor gives it away.
The mystery is why no-one went back to F+P to redesign it in line with the changing market. In this story, it’s wrong to see UK tax-exile architect Baron Foster of Thames Bank as some sort of victim.
But Two World Trade Centre is much more than a redesign because construction of 200 Greenwich had already begun!
Many structural elements of the skyscraper came predetermined by the intricate underground architecture of the property, which was set in place by Port Authority and Libeskind’s master plan. Mechanical equipment, like air vents for Calatrava’s station, are positioned on the existing foundations and had to be incorporated into Ingels’ building. [WIRED]
BIG used the same engineers as F+P. I’d insist on this if I were the client-side project manager or property development manager. Continuity of structural teams is good, especially when there’s suddenly an asymmetrical loading creating a rotational moment that’s usually countered by an extra thick and heavy core. The fun of Twister is to resolve your rotational moment before it reaches your hands.
I’m no engineer but I think this means a big block of concrete resting on the foundations of another building. We’re told this is “expressive architecture” rather than something useful that stops the building twisting itself off its foundations.
The engineering is of course possible but it’s not cheap. The 14% MORE must come at an acceptable price. The WIRED article covers points ignored by other articles – namely the apparent instability thing.
Silverstein was initially skeptical of the architect’s stack-of-blocks concept. From some vantage points, such as North Brooklyn, the structure will look a little off-kilter—almost as if it is leaning. At the World Trade Center, the force of gravity is the last thing that an experienced developer like Silverstein wanted to bring to mind.
“Rupert Murdoch, still the ultimate decision-maker when it comes to his companies’ business, initially shared the developer’s concerns. “Once it was fully explained to him how the building works so well, so efficiently—brilliantly, I would say—then he got very comfortable,” Silverstein says. “As a result, quite honestly, I became comfortable too.”
Through the eyes of a Manhattan property developer, unexploited permissible envelope must appear like translucent green boxes in the sky. The F+P site layout no doubt provided the maximum possible footprint but only as determined within the constraints of multiple symmetries based on the edge of the wedge. This fixation with symmetry created two mini-wedges of light on the south-west and north-west corners. Nobody asked for those.
Silverstein may well have approached F+P for a re-think and F+P, sensing a PR disaster, may have refused. It’s bad enough to be accused of failing to have predict the future. Enter BIG. Their design occupies these mini-wedges. The south-west one becomes that sombre vertical and the north-west one is filled with boxes tracing the imaginary diagonal.
F+P’s design was resolutely vertical apart from its large trading floors where the BIG design now begins its climb. Thisis where most of that 14% more comes from. As it rises, the building contracts in one direction but extends in another, thus maintaining that gain for longer. The overhang is a logical consequence of maximising leasable area. It’s not an aesthetic decision.
Even if the achieved areas are the same, it still makes more sense to overhang the building towards the top and achieve more premium-office space, rather than step it back from the bottom and more sub-premium office space with yet more gardens.
“My first reaction, my second reaction, and my third reaction were: ‘Will this work?’” Silverstein says. “Will it be respectful of the other buildings? Will it be respectful of the memorial below?”
Here, Silverstein is referring to the PR aspect of the problem, not its aesthetic one and certainly not any functional one. Like Nature filling a vacuum, the building designs itself and engineers itself to fit. What’s really needed is experience in winning over public opinion.
BIG step up to the plate.
Much skill must have gone into redesigning this building to monetise every cubic foot of permissible envelope and then engineer it so it stands on foundations constructed for a different building. This is nothing to be ashamed of yet we’re told none of it. In the new architectural dysfunctionalism, performance is completely detached from architecture even when it’s generating it.
The media star architect is a new form of architectural ornament. Their function is to invent and present decorative yet empty narratives. The actual building is conceived of and made possible by others. The only time the media architect is of use is to divert our attention away from the sordid political and economic machinations responsible for the building in the first place.
- Talk about shape rather than volume is a classic example of how a dysfunctional architecture disguises real performance criteria as an aesthetic decision
- Talk about vital engineering solutions as “expressive architecture” is another example
- Representing diversity rather than encouraging it in any real sense, is merely architecture in motion. It’s the same process by which space and light were turned into aesthetic commodities.
- It’s now possible to identify what exactly it is architects do to sustain this situation
- Because of this, it’s now possible to explain the mechanism by which architectural fame is created. It’s a reward, basically. This explains not only the actual function of starchitects, but why they exist. The more an architect can get away with not justifying their buildings in terms of any aspect of real performance, the more value they have to a certain type of client. This is the source of many diseases presently plaguing architecture.
- It now makes sense why media fuss and controversy of aesthetic appropriateness and symbolism is welcomed and encouraged by media, architects and clients alike. Everyone works overtime to confine the “debate” to aesthetics.
“it’s none of my business” (Zaha Hadid)
“the Building of The Year Award is about architecture not politics” (Deyan Sudjic)
The more intense the debate about how a building looks, the more attention is diverted from how buildings are used for economic gain and political prestige. Architecture of this kind is The Shock Doctrine applied to economic and political exploitation.
In his presentations, Ingels spends a disproportionate amount of time and energy talking about Tribeca. There must be translucent green boxes hovering all over it.
1. Convince people the diversity of Tribeca can be represented in a high-rise building.
2. Replace Tribeca with representations of Tribeca.
