The Seoul neighbourhood of Hannam-dong, overlooking the Han River, is home to some of the wealthiest households in South Korea (the family of the chairman of Samsung among them). Here, on the hill above the Samsung-owned Leeum Museum, the houses are grand, but that is not the only reason they look quite different from those in the rest of the city. These homes are largely completely blocked from view from the street, with high walls and fences sheltering the high-profile properties from prying eyes.
