SEOUL | Lotte World Tower | 555m | 1819ft | 123 fl | U/C

I'm not a big fan of that crown, but otherwise it's one of the best proposals that I've seen this year.

fantastic news, i believe it'll be built

and 70 x 70 metres on the base !!

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.

[CULWULLA]

love the design. lets hope it actually gets built.

[philvia]

that's pretty fugly hahaha it is pretty interesting though to see it go from sqaure to a circle

[giovani kun]

so this one is also in SEOUL hmm we have a 555m(approved) and a 622.5m Yongsan Landmark Building (site prep) in this town fantastic for them

[wjfox]

Donkie, why did you bother posting the exact same article and photos that I already did?

[Þróndeimr]

Good looking tower, hopefully we will see this one get built, and that soon, not in 15 years as other S. Korean supertall high-rise projects!

Two different designs? so which is which?

[ZZ-II]

the design in the first pic is the old one

[Cliff]

it looks so strange...

[AltinD]

I don't know what plans are for the area around, but this kind of shapes don't look good as landmark stand alone towers, they would look much better within a dense skyline.

[skyperu34]

Very interesting design, i really like it so much ! Now there are two lotte towers !

[CarlosBlueDragon]

nice picture~~!!

[gothicform]

haha. yes, i have plenty of 500m+ buildings to announce... which one to do next i wonder. ho-hum.

[jcal5]

marvelous yet ugly...

[Middle-Island]

I agree with some of you. The HAVE to do something with that crown. It just looks like a wire waste basket. It's too commanding a structure to end like that. It makes it look unfinished somehow. Maybe it would work if they ended it with three or four antennas/spires. Other than that, the transition of its shape going up is a spectacular concept.

[CrazyDave]

Interesting design!!! I've seen so many of these supertalls that never actually get built. Lets hope that this one does.
