They are working together as one structure. Glass façade, roof and staircase The bent glass façade is composed of cold bent double laminated insulated glass units. This means the rectangular glass panels have been shaped on-site during installation. The total area is approximately 650 sqm. The façade has 20 glass fins which are all unique. The longest façade fin is 9,4 meters. The glass roof with a total area of approximately 600 sqm has as main geometry a shell under an angle of 16,5 degrees. There are 30 glass roof fins, all unique in length and with an optimized height to accentuate the shape of the curved roof. The longest glass fin in the roof (also the longest structural glass fin in the Netherlands) has a length of 12 meters. The glass staircase is supported by a triple laminated glass arch which transfers the highest loads from the stairs and also stabilizes the staircase. Because of this glass arch, the amount of steel is kept to a minimum and the staircase can be seen as a transparent piece of furniture. LED lighting has been integrated inside the glass stair steps. “We ensured that the new entrance hall has become light and spacious with lots of glass. We want to capture the sunny atmosphere, which you see reflected in many paintings of Van Gogh. We developed a unique support structure for the glass roof, which you hardly notice. As you enter, you will wonder: How is that entire glass building supported? And what you experience is light, space, and overview. Clarity is extremely important, maybe the most important; you have to realize that a museum is a public building where every day thousands of visitors, many foreigners also, often come for the first time. You need to provide clarity. The visitors don’t want to miss anything; they need to understand immediately which way to go, how big the museum is and how long they will need to see it. When they feel at home and at ease they will stay longer and love to come back.” Architects: Hans van Heeswijk Architects www.heeswijk.nl Photographs: Ronald Tilleman, Luuk Kramer Page 43 - Archetech
