The undulating, metal roof at the VanDusen Botanical Garden Visitor Centre in Vancouver, Canada, won the 2013 Metal Roofing Award from the Metal Construction Association because of its design and structure. The roof spans more than 11,840 square feet and is made of a glulam wood structure topped with the architectural detail of aluminum panels known as "Alucobond." The pitch of the structure varies from 2 degrees to 55 degrees and features five petals rising from a central skylight.
