The unique ‘Children’s Activity and Learning Centre’ at the 6-star Soneva Kiri resort in Thailand is a study in sustainable construction. Dutch firm 24H-architecture designed the bamboo building as a way to provide visiting children with a wide range of entertaining activities that could raise their level of ecological awareness. The “Den,” as it is called, provides a number of outposts, including an auditorium for films, lectures and plays; a library filled with books on permaculture and local traditions; an art room; a music room; and a fashion room offering children both a creative and ecological destination to learn. The center’s manta ray-inspired bamboo dome is perched at an elevated position, seemingly ready to launch itself into the bay from the location on which it is perched.
