Hash-shaped skyscraper planned for Seoul, South Korea

If you thought that the only place to find a hash-symbol was on a computer or phone keyboard, then you’d be wrong.

Spectacular artist’s impressions have been released of a hash-shaped skyscraper planned for Seoul, South Korea.

The proposals reveal that the gravity-defying building will be constructed in the bizarre design to maximise square footage and meet vertical height requirements in the city’s Yongsan business district.

Named the ‘Cross # Towers’, the architectural oddity will house more than 600 high-end residences along with amenities, including a library, gallery space and kindergarten.

One tower will be 214m high and the other 204m, they will be linked by public bridges at different levels – underground, street level and in the sky.

Designed by Danish architectural firm BIG, the upper and lower horizontal bridges would connect the two towers at 140m and 70m up.

The top of the upper and lower bridges will offer breathtaking views of Seoul’s skyline from sky gardens that will be accessible to all residents for recreation and leisure purposes.

Speaking about the design, Thomas Christoffersen, from BIG architects, hoped that the unusual building will encourage residents to socialise.

“The typical tower inherently removes life from the city it occupies. Circulation is linear and social interactions occur only in lobbies or awkward elevator rides. We propose a building that triples the amount of ground floor - triples the amount of social interaction and reintroduces the idea of neighbourhood within the tower complex,” he said.
