I am kinda confused, which should I call it Busan or Pusan?

Doesn't really matter - Pusan is the English version, Busan is closer to what Koreans would say: they don't use the Latin alphabet though, so I guess those that DO use it should have right of say. When my Korean wife says it, it sure does sound like a "p" sound to me, but she insists it's really closer to a "b."

Either way, both ways of writing it are closer than Prague vs. Praha, for example...

^Oh I see! Thanks

Same here. This project has draged on for so many years and I have never really cared for it.

I remember back in 2000 when I posted at the old skyscrapers.com forum this thing was supposed to be under construction, ableit with a lower height (1532 ft AFAIR) and different design.

This tower may look odd in the city with no other building with comparable height nearby...

NOW

BUSAN LOTTE WORLD 2 - 510M !

Lotte World Tower To Become Seouls Tallest
Published on 2007-07-07

These are the first images of the latest design of what will be one of the tallest buildings in the world, the Lotte Super Tower in Seoul, South Korea, if built.

Designed by leading architects Skidmore Owings & Merrill, the tower will be 555 metres tall tapering gently from a wider base. The shape of the building is also manipulated starting off with a square floor-plate of 70 x 70 metres and gradually morphing into a circular 40 metre one as the height progresses.

Responding to the shrinking floor-plates, the building uses which require the largest areas such as office and retail will be located at the bottom of the tower whilst the upper floors will be set aside for hotel accommodation and a viewing platform. In total it will be 15% retail, 50% office, 30% hotel and 5% for the observation area.

The appearance of the building is dominated by lattice-work that takes on the look of a diagrid, famously used in 30 St Mary Axe in London and less creatively but just as famously in a defining SOM skyscraper, the Hancock Tower in Chicago.

This webbing of metal has one major advantage over the traditional steel-framed buildings of having much stronger structural strength so less metalwork can be used and building costs are saved by the developer.

The diagrid can also be configured by the architect in the design process to adapt to such things as structural loads in a way that a more stricter frame could not. This was seen in action with 30 St Mary Axe which actually shrunk a fraction of an inch when completed as the frame compressed slightly to hold the weight once gravity kicked it and it settled into the site.

Responding to potential strains on the Lotte Super Tower, SOM has designed the structural columns so they are steepest at the bottom to take into account the gravity loads and shallowest at the top to take stresses from the wind in a process called "vortex shedding" that manipulates the wind flow.

At night the superscraper will be particularly stunning. A lighting scheme has been designed where the diagonal cross-bracing that wraps around the tower will be lit up with a series of white lights like a Christmas tree. At the top, beams will shoot up from the crown illuminating the sky above as if the structure finishes in a torch light.

Particular attention has been paid to the base that will have blue uplighters but also a deeper red colour scheme on the interior of the lowest levels, creating a feeling of depth through the facades and cross-bracing as well as expressing the complex structure visually.

The Lotte Group are already a major developer within Korea with a number of large towers on their portfolio but this one will be one of the tallest buildings in the world if it is actually completed. That could however be another story - Korea has a long and illustrious history of proposing enormous towers that fail to get off the ground.

Even if the scheme is never realised it's a far cry from the earliest origins of Lotte, that of a chewing gum and confectionary manufacturer in Japan in 1948, and a victory of sorts that shows the smallest starts can lead to the grandest designs.

This building has some great design features. At the base, the Lobby is made enormously tall, by pulling the structure out creating a continuous vertical gap of space that makes the space appear much taller. It is a highly engineered diagrid that was generated so that all members could be straight, creating an efficient system, and the connection points between the members become quite complex with the curtain wall.

Overall I think the design is good, though I wish that the top would be done somehow differently.. the open lattice isn't doing it for me. Even though it is cool that it is expressing the structure all the way and the lighting looks badass at night, I think maybe a better version could finish the tower off more interestingly?

I'm glad I checked this thread today.

... anything new?

I clicked on the first page and couldn't figure out what I was looking at. 1600 ft. is the world's tallest? What?
Then I realized the post was from 2005.
Wow, a trip in the way-back machine, to when 1620 ft would be a world record... Wouldn't even make the top 5 now.

I like the diagrid design, not sure about the lighting theme however.

This thing is in trouble according to ssc. Lotte has corruption trouble, there is a rendering showing a mall with maybe a 10 story building on there. The translation from Korean to English was crappy. Would not surprise me if this thing is on indefinite hold or dead.

may look = looks imo

Not a great view either. Front row seats to the industrial ship yard across the river.

The news on this project is as messed up as the project itself. It says in the article above that is is in Seoul. Busan is no where near Seoul. So where is it?

There are two Lotte supertall projects, one in Seoul and one in Pusan. I don't know why the Seoul project's renderings were posted in this thread.

Supertalls in Busan
 

I was looking at the posts about the supertall projects in Busan, and thought I would try to help out, since I'm now working here in Busan City Hall.

Anyway, first up, it's Busan, not Pusan. The spelling system officially changed back in 1997, as far as I can recall. It's not Haewoondae, but Haeundae.

Finally, I saw the Lotte 2 construction site today, and the basic steel structure of the lower-rise buildings adjoining the tower is about seven stories high so far. I've asked for some kind of official confirmation on the project's progress from coworkers, and will post it when I have it.

A supertall version of the Hearst Tower in NYC?
