This eight-storey, £78m landmark building project completes the Darwin Centre, the most significant development at the museum since it moved to South Kensington in 1881. The first phase, housing the Natural History Museum’s 22 million zoological specimens stored in alcohol, opened in September 2002.
The new Darwin Centre is a state-of-the-art scientific research and collections facility that will be used by over 200 scientists at a time. It is also an awe-inspiring new public space inviting visitors to explore the natural world in an exciting and innovative way. The architectural highlight is a 65-metre-long, eight-storey-high cocoon – the largest sprayed concrete, curved structure in Europe. It will safeguard the 17 million insect and three million plant specimens held inside the building. Visitors will journey into and around the cocoon to see how Museum scientists work, with a chance to see into the collections and laboratories.
Dr Michael Dixon, director of the Natural History Museum, comments: "As well as being a world-famous visitor attraction, the Natural History Museum has hundreds of our own scientists and thousands others who are visiting, all working with our 70 million specimens – from meteorites and dinosaur fossils to Darwin’s finches and the Thames Whale. Until now most of our science has been going on behind the scenes.
"At the Darwin Centre, we will show the public more of both our vital research and our internationally important collections. There is no other museum in the world that brings the public and scientists together in this way or on this scale. The Darwin Centre will I hope inspire people to think about the natural environment differently and in turn inspire them to take better care of our planet."
Visitors to the second phase of the Darwin Centre will experience:
Inside the cocoon – an interactive journey. Up to 2,500 people a day will go into the cocoon, deep into the heart of the collections and get a glimpse of the working life of world-class researchers.
David Attenborough Studio – celebrates excellence in science communication. Through natural history film footage, new media and face-to-face encounters with Museum scientists, visitors to the studio will be inspired to be naturalists, observing the natural world and debating our relationships with it.
Angela Marmont Centre for UK Biodiversity – an area dedicated to the study of nature in the UK. This will offer new opportunities for the UK’s many wildlife groups and societies, access to our UK collections and a place to get first-hand information about the natural world from Museum experts.
Inspirational architecture – a stunning and unique building with a gigantic cocoon and breathtaking views over west London. 
The new Darwin Centre in numbers
-
The second phase of the Darwin Centre will cost £78m
-
The base construction took around 25 months and 280 people to build
-
At 60m long, 12m wide, 300mm thick and 3,500m2, the eight-storey-high cocoon is the largest sprayed concrete, curved structure in Europe
-
The cocoon will hold 17 million entomology specimens and three million botany specimens in 3.3 kilometres of cabinets
-
These cabinets would stretch from the Natural History Museum in South Kensington to Westminster Cathedral if put end to end
-
The cocoon is approximately 300mm thick and will be kept at a steady 17°C and 45% relative humidity, the optimum conditions to store collections
-
The new Darwin Centre will have 16,000m2 of floor space
-
The building will accommodate 220 staff and science visitors
-
There will be 1,040m2 of laboratory space, doubling the size of the Natural History Museum’s current laboratory areas
-
2,500 people per day will be able to take a self-guided journey through the collections and research areas
The second phase of the Darwin Centre is designed by Scandinavian architects C F Møller, who won an international architectural competition in 2001 and is being built by HBG UK. The project's major supporters include the Heritage Lottery Fund (£20.5m), The Department for Culture, Media & Sport (£10.7m) and The Wellcome Trust (£10m).
