winning a competition in 2007, german practice schneider + schumacher has completed the 3,000 square meter ‘extension to the städel museum’ in frankfurt. taking up the garden of the original museum built in 1878, the addition is the first to be located entirely under ground. in the concrete roof covering the space, 195 skylights dot the surface ranging from 1.5 to 2.5 meters in diameter as they reach the spherical protrusion in the center of the site.

from the exterior, a gradient grid of skylights in a grass field allows users to walk on a unique garden; from the interior, a matrix of roof openings with integrated shading systems will bring in plenty of indirect sunlight to illuminate the artwork, with the ability to blackout the glazing entirely. a new set of storage and technical functions are accompanied by the exhibit halls ranging in height from six to eight meters. only 12 columns support the pre-stressed canopy freeing up the space for large flexible spans. geothermal heat pumps beneath the structure help to maintain comfortable temperatures, using the earth’s mass as an effective insulator. a ventilation system will cool the exhibit spaces in the summer as well as humidify or dehumidify them.
