The Depot Boijmans van Beuningen is a new building in the Rotterdam Museum Park and hosts the first museum art depot worldwide which is entirely accessible to the public. The spectacular glass façade reflects the surroundings and makes the building merge into the Museum Park. To minimise the impact on the existing park, the building was designed in the form of a bowl with a small footprint on ground level, widening only further up towards the roof. This form allowed for the creation of an even bigger park surface on the roof than the building took up on ground level. It is no coincidence that the Depot won the Rooftop Award 2020 for the most eye-catching design in the Netherlands: A public restaurant situated in the midst of a “rooftop forest” consisting of 75 carefully selected and pre-treated multi-stemmed Birch Trees with an especially slim root ball. Because of their impressive size of approx. 6 m they had to be lifted up onto the roof with a telescopic crane. The watering system is supplied with stored rainwater. However the green roof is not the only sustainable design feature. The goal of obtaining a BREEAM Excellent classification is also based on a combination of geothermal heat exchange, solar panels, LED lightning and a high-class insulation. Rainwater is collected and used for roof irrigation and toilet flushing.

  • Roof garden with Birch trees
    The root balls are anchored to the ground to with-stand the high wind loads on the roof.
  • Roof garden with Birch trees and water system pipes
    Collected rainwater feds the watering system.
  • Substrate and trees are lifted onto the roof with a roof garden
    The substrate and the trees both are lifted onto the roof with a telescopic crane.
