The name “Waterfall House” comes from the waterfall feature located at the center of the house. This waterfall feature is a result of a split-level design, which aims for a connection in both visual and accessibility aspects between living spaces. The sloped surfaces of the waterfalls have two functions: dividing and connecting. For the dividing function, the sloped slab makes the half-level separation of parking space and lower level living space possible, with no wasted space. For the connecting function, the slope becomes a pleasant waterfall that links the lower and upper living spaces.
