Regulated by Rem Koolhaas’s master plan for the urban center of Almere, the De Kunstlinie building offers large and small-scale cultural equipments scattered on a tray that hovers over the surface of Weerwater Lake. This horizontal piece of 100 x 100 meters, partly anchored to the shore grounds and partially resting on piles over the water, is sectorized in orthogonal spaces of different size as a series of attached rectangles. Over the horizontal base, four volumes house the more specific spaces of the program such as the grand theater, two auditoriums with offices on top, and recording studios. The remaining uses, related with the development of artistic activities, are organized in spaces of different size that configure the horizontal base of the building. The courtyards that illuminate and ventilate this base create a series of flexible rooms that are easily recognizable and connected without hierarchy, permitting a more flexible use of the center’s services. The use of glass on the perimeter facades and in the interior courtyards creates visual continuity between interior and exterior, connecting the rooms and opening them up to the panoramic landscape of the lake.
