Nickolai Børne Kulturhuset, Kolding, DK

The top floor of the Nickolai Kid's Culture House in Kolding, Denmark contains a unique lighting situation. A skylight is carefully positioned over a glass-bottomed ball pit. Daylight enters through the skylight and lights the top floor playroom. Then, the light travels through another layer of glass to add some daylight to the art room on the floor below. These diagrams show how the light enters the space.

The ball pit serves to diffuse the daylight so that the art room does not receive direct light. In this photograph, one can see the glass of the ball pit, as well as the art room below.
