Seongsu-dong is called Ttukseom because it is close to Jungnangcheon Stream and the Han River, but it is not an island. Compared to Gangnam across the river, land price is cheaper, so small and medium-sized factories were concentrated. After the 1990s, handmade shoe factories began to gather. From the 2000s, office space, an apartment-type factory, was created, and after 2008, it was replaced by a knowledge industry center.

Seongsu-dong shoe factories began to close one by one, being pushed by cheap shoes that were automatically mass-produced. Now, about 350 handmade shoe factories remain. In Seongsu-dong, venture companies including IT companies have moved into the knowledge industry center to form an IT industrial complex.

As gentrification progressed in the Seongsu-dong factory area, it was reborn as Seongsu-dong Handmade Shoe Street. In addition, the old factories have been remodeled to create many office spaces for young startups and exhibition spaces for artists, transforming them into hot places. Therefore, it is very similar to Brooklyn, New York. The characteristic of Seongsu-dong is that the red brick factory and houses still remained. Without demolishing the existing factory building, some of the interior has been renovated and used as various spaces. There are many cafes, pop-up stores, restaurants, exhibition halls, and studios. In particular, restaurants, cafes, and pubs are concentrated around the alley of Yeonmujang-gil.

Dongdaemun Design Plaza, designed by Zaha Hadidi, who was born in Baghdad, Iraq and studied architecture in England, is the only building in the world.

Dongdaemun Fashion Town is being created by redeveloping the place where Dongdaemun Stadium used to be.

Construction began in 2009 and opened in March 2014. Dongdaemun Design Plaza, built with an atypical curve, was built by Samsung C&T using 3D BIM techniques.

It has a total area of 87,000 square meters and consists of three basement floors and four ground floors. The highest point is 29 meters.

There are market, design lab, museum, art hall, Dongdaemun History and Culture Park, and Dongdaemun Stadium Memorial Hall. On the bridge to the future, we can feel two different vibes. First we can see Dongdaemun area of the past and the Dongdaemun area of the future. There are Dongdaemun Stadium Memorial Hall and Dongdaemun History and Culture Park History Hall in the east. And to the west, it is Dongdammun Fashion Town.

If you look in the air, you see a protruding building in the shape of a spaceship made of cantilever techniques.

The cantilever technique is fixed with one steel structure and the other is a free space.

It's the principle of supporting the building using tensile force.

And, it uses the megatrus method to support the entire building. The exterior wall is covered with 54,133 pieces of aluminum panels of different sizes and shapes. And the pillars of the building stand on the inside and are not visible from the outside.
