Near the old center of Delft, a daycare center and out-of-school care were needed. The concept of the building is the spiral, which symbolizes the growth of a child, as he discovers new things while walking or crawling through the building.
The route architectural of the spiral is an accumulation of play spaces and activity spaces, the only obstructions are formed by the group spaces and necessary spaces. Changing sightlines and voids are used as elements of surprise. The spiral culminates in the rooftop play area, where a “secret” staircase or slide takes you back down to the partially covered play area.
