The John Hope Gateway is a threshold into the world of the Botanic Garden, as well as to the visitor facilities and event spaces. It houses exhibitions, indoor and outdoor education spaces, a media studio, shops, a restaurant and a new biodiversity garden.A porous ground floor allows visitors to enter and leave the building from different points and flow freely into different areas of the building. A curved glass wall looks out onto the biodiversity garden, taking the interpretation story of the Garden into the landscape. The upper floor contains flexible event facilities and catering - a space that can accommodate large assemblies of visitors.The building includes various demonstrable low energy environmental solutions, including a biomass boiler, a green roof for rainwater harvesting, a wind turbine, natural ventilation and passive night-time cooling. The material palette and the floating matrix structure of timber glulam beams and slabs, supported on pencil thin columns, uses many locally sourced materials.Flexible spaces that can change and respond to topical events are allied to a permanent exhibition. The public are able to interact closely with the scientists and researchers in a 'Real Life Sciences' studio and botanists at work around the world are able to interact via a media centre.
