Chester Zoo Islands

Planning the Islands represented a challenge for us on a number of levels. Chester Zoo’s objective was for the new attraction to increase its appeal with visitors and extend visitor stays by 1.5 hours as well as strengthen the role of the off-season. In addition, creating the best conditions for the animals was a priority as well as communicating and bringing to life themes of biodiversity and nature conservation. Since opening in summer 2015, residents of the six islands of Panay, Papua, Bali, Sumatra, Sumba and Sulawesi include orang-utans, macaques, hornbills, Sumatran tigers, crocodile and others animals. All twenty-two species living in the immersive environments, some of which are part of Chester zoo’s actual conservation programs, have been situated based on their actual geographical habitats. Our storyline, which revolves around a team of conservationists and focuses on Southeast Asia, creates a direct link to Chester Zoo’s conservation programs. During their expedition on the Islands, visitors discover the uniqueness of this region’s flora and fauna and learn a lot about their fragility and their treasures. Visitors not only move around on foot, the Islands can also be explored on a 450 m long boat trip. Fourteen boats individually designed in a Southeast Asian style can accommodate 238 people at a time for fifteen minutes of animal watching and enjoying the magic of the Islands from a completely different perspective offering deceleration and a feeling of proximity to the animals. We designed and constructed a total of fourteen Indo-Pacific style structures as well as a variety of building types including stall facilities, visitor buildings, a boat station and several bridges all down to the smallest detail. We were also responsible for the aviaries, the climbing structures and the extensive modelling of the terrain. The Monsoon Forest represents a modern contrast and architectural highlight. The show house, stands out for its highly efficient form and function. Because only the roof is primarily visible from the outside, it blends seamlessly into the landscape. The roof’s airy ETFE-membrane also allows the transmission of UVA and UVB rays important, for both animals and plants. Awaiting visitors inside is a jungle pathway topography flooded in daylight, a biotope with paths leading through various levels of rainforest, where occasionally it actually does rain. This attractive leisure destination was awarded the INCA Award 2016.
