# Twin Towers 3D

> Twin Towers 3D (twintowers3d.com) is Dan Danaher's 3D reconstruction of the original World Trade Center in New York as it stood in 2001: both towers, the Marriott hotel, WTC 4 to 7, the plaza and the concourse underneath. It is modelled in Blender from the original architectural drawings and photographs, and will be explorable in a web browser. It is a work in progress, last updated 10 November 2026.

The site is a single page, written in lowercase on purpose.

- 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.
- Progress: 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. By layer: layer 1, the ground and outer shells: done in 8 of 16 areas; layer 2, structure, stairs and lifts: under way; layer 3, facades: under way; layer 4, walls, doors and ceilings: under way; layer 5, fittings and finishes: to come; layer 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.
- Latest log entry (10 nov 2026): 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.
