WorldTowers: three supertall towers you can fly through

A design by John Elia: three tapering octagon towers in smoke glass, the tallest reaching 1,080 m to the tip of its spire, with a resort in the sky, a transit hub fifty levels down and a park full of life around it. It isn't a set of pictures. You fly through the model in your browser.

What it is

Three towers in a triangle, 75, 150 and 250 storeys tall. The tallest reaches 1,000 m to the roof and 1,080 m to its spire, taller than the Burj Khalifa. Twelve pods spiral up it to a sky crown of seven sky mansions and five sky castles. An 18-storey hexagonal ballroom sits on the shortest tower, plugged into the other two, with a rooftop resort: pools, a lazy river and a waterslide 372 m up.

Underneath are 50 basement levels with a water-taxi basin, four subway lines, a railroad station and parking. Around it are estate grounds with canals, and a perimeter park with walkways, a jogging loop, a bike loop, cafés, shop streets and dog parks.

Who it is for

Anyone who likes skyscrapers, cities and architecture, and wants to stand in one rather than look at a render. It runs on a computer, tablet or phone with nothing to install: about a 6 MB download.

How it started, and how I built it

It started as three towers and kept growing: first taller than anything standing today, then a resort on the roof, then a city underneath and a park that feels alive.

  1. Modelled in Blender. Every tower, pod, canal, café and walkway is built in Blender, with each version kept in its own release folder so nothing is ever overwritten.
  2. Flown with three.js. The model exports to a single compressed file that a browser can load in seconds, with walk and fly controls for keyboard and touch.
  3. One-tap views. Buttons jump straight to the aerial view, a café terrace, a dog park, the bike path, the shops or the top of each tower.
  4. Released like software. Each fly-through is a numbered release. Version 1.00.00.1 shipped on October 28, 2026; 1.00.00.2 adds avenues, a commercial district and more realism.

What it shows I can do

  • Taking an idea from a sentence to a 3D world people can explore, and shipping it to the web.
  • Keeping large 3D work fast on phones: one compressed model, cached, with controls that work by touch.
  • Running creative work with release discipline: numbered versions, nothing overwritten, every release still online.

Questions people ask

Is this a real building?

It's a design by John Elia, modelled to be explored. The towers are massing models: their shape, height and glass, without floor plates or window detail yet.

Do I need to install anything?

No. It runs in a modern browser on a computer, tablet or phone.

Will there be new versions?

Yes. Version 1.00.00.2 is in progress, and every earlier version stays online to fly.
