The concrete tested flawlessly, with no rusted steel inside. Its quality is outstanding\u2014I\u2019m confident it\u2019ll last another 150 years,\u201d says van Kampen, highlighting how repurposed materials align with the university\u2019s future-proofing strategy.<\/p>\n\n\n\n<p class=\"size-regular\">The Sequoia redwood ceiling panels were repurposed as wall cladding in the atrium. They were carefully milled in collaboration with BWRI, a social development organization supporting individuals with disabilities and other employment barriers. The slats\u2019 specific pattern allowed for prefabrication and installation, minimizing waste.<\/p>\n\n\n\n<p class=\"size-regular\">\u201cWe had around 65,000 square feet of ceiling wood available, but we used only around 43,000 square feet.

The design blends indoor and outdoor spaces with a butterfly garden, bird nesting spots, and insect habitats. The climate-adaptive front square mitigates heat and absorbs rainwater, promoting both social interaction and environmental well-being.<\/p>\n\n\n\n<p class=\"size-regular\">This balanced focus on long-term sustainability mirrors van Kampen\u2019s approach to architecture. Despite the challenges posed by Cluster Zuid\u2019s protected status, he advocates stricter preservation to minimize unnecessary demolitions, emphasizing that buildings should be valued as long-term assets.<\/p>\n\n\n\n<p class=\"size-regular\">Van Kampen concludes, \u201cWe should protect more buildings to prevent their demolition too quickly. Buildings aren\u2019t disposable products to be discarded after a few decades.\u201d <\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<iframe loading=\"lazy\" width=\"1200\" height=\"500\" src=https://metropolismag.com/"https:////www.youtube.com//embed//vJnYwgA05dM?si=uqQjsEubMUNkKd8O\%22 title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n\n\n\n<p class=\"size-regular\">Video credit: De Zwarte Hond &amp; Harryvan<\/p>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"comment size-regular\">Would you like to comment on this article?
