New York-based architect Daniel Libeskind has won a competition to redesign an entire district of Seoul in South Korea.

Working with ARUP and Martha Schwartz Inc., Libeskind will create a masterplan to transform the Yongsan International Business District.

The US$20bn (£12.5bn, 14.3m euro) project involves a series of skyscrapers alongside the Han River, designed to be "islands" in a sea of green space.

Libeskind said: "The idea is create a 21st century destination that is at once transformative, vibrant, sustainable and diverse.

"I wanted to make each form, each place, each neighbourhood as varied and distinctive as possible. The plan, and each building within it, should reflect the vertical and cultural complexity of the heart of Seoul."

Other firms competing were Asymptome, Foster+Partners, Jerde Partnership and Skidmore Owings & Merrill.
