> the world trade center as it stood in 2001, rebuilt floor by floor. soon to be explorable in your browser.

## what it is

a reconstruction of the original world trade center complex: both towers, the marriott, wtc 4 to 7, the plaza and the concourse underneath. i’m building it in blender from the original architectural drawings and thousands of photos, and it runs in your browser. one day soon you’ll be able to ride the PATH train, meander through the mall, exit through the tower lobby, perhaps ride the express elevator to the observation deck, and explore the entire complex yourself.

## why

some events are so large, so unprecedented, that they cast a shadow in time.

a shadow that stretches for generations, so looming it can’t be escaped. 9/11 is one of them. my fear is that it’s being forgotten: people don’t notice they’re still in that shadow, and many born after don’t realise they’ve never stood in the sun. i only know the towers from photos and film, and i’ll never get to stand there. but i think being able to walk through them, to grasp the scale, can help people realise what was lost.

the complex was a small city. a subway hub, a mall, a hotel, a restaurant on the 107th floor, tens of thousands of people at work every day. i want to put it back together as carefully as the record allows, so people who never got to visit can, and people who did can go back.

## how it’s built

every piece starts with a source: an architectural drawing, a photograph, a tenant list, a written account, or something else. the modelling is accelerated through the use of agents, in layers, building fidelity with every pass. every change is reviewed by me, scrutinised, and compared against the sources before it merges. if no reliable reference can be found, human judgement is used to make an educated best guess. an agent will never invent something that can’t be evidenced, and everything that isn’t verified by a source is recorded, waiting for reliable reference to turn up. i’m working on a way that you can help with that.

## where it’s at

the model goes up in six layers, area by area: each building, the plaza, each street, the concourse, the PATH station and the levels below finish one layer before starting the next. the first is done for both towers, wtc 4, 5 and 6, church street, the concourse and the PATH station, and every floor of wtc 4, 5 and 6 can now be reached by stair.

1. the ground and outer shells: done in 8 of 16 areas
2. structure, stairs and lifts: under way
3. facades: under way
4. walls, doors and ceilings: under way
5. fittings and finishes: to come
6. furniture and loose things: to come

## the walk

the walk runs the model in your browser, inside and out, at real scale. it updates automatically so you’ll see the latest changes as soon as they’re finished. it opens once layer 4 is finished.

the city’s landmarks, one at a time: the world financial center and its winter garden, the woolworth building, st paul’s chapel, 90 west street, 40 wall street and 70 pine.

the walk’s controls in a windows 2000 window you can drag around, and gentler light: the haze, the clouds and the sun’s glare all reworked.

the tower stairs rebuilt at the root: each landing shared by the floors it joins, and every riser as drawn.

the city of 2001 around the site: buildings for sixteen kilometres, the rivers, the streets and sidewalks nearby, and lights in the windows after dark.

the marriott bends in the middle, and its plans now turn at the right point: the shorter wing moved about 70 cm, closer to where the 2001 aerial photos put it.

the walk: the whole complex in your browser, in first person. it made mistakes really easy to spot, and every note i took in it went back into the model.
