Rivers have always been natural frontiers. Like a river, the border, between North Korea and South Korea, flows and folds around spaces in which are the hot springs.

Like traditional Korean vessels, the main spaces of the bath are concave, open to the sky with a skylight acting as the connection between the spa and the gardens. The rest of the program is concentrated around these light-filled spaces.

The citizens of North Korea can thus visit South Korea without leaving their country and vice versa.
