"Designed by Zaha Hadid, this silver-grey spaceship crash-landed in central Seoul in 2014. A massive cultural complex, the Dongdaemun Design Plaza hosts exhibitions, fashion shows and more. Hadid’s design – which won a competition held by the government – mirrors the dynamic Dongdaemun area in its free-flowing curves (it’s the world’s largest 3D amorphous building). The cladding is made up of 45,000 aluminium panels, which look different depending on the time of day and year. Drop by at night and you’ll see them glow with the reflection of nearby neon signs."
