Casson Mann has been selected as exhibition designers for the Natural History Museum's new Treasures gallery, which forms part of a wider redevelopment at the London attraction.

The gallery will be located at the top of the North Staircase and will open in 2012 in the first phase of the Central Hall scheme, displaying some of the museum's "greatest treasures".

Casson Mann will be tasked with creating a space that highlights the connection between the museum and its wide range of specimens, natural history objects and other artefacts.

A spokesperson for Casson Mann said: "Our response is to create a centrally placed, simple, dramatic, display plinth that has a clear relationship with the museum's very distinct architecture.

"The objects, each with its own unique story, stand alone on this plinth, displayed in individual cases, but held together by the strength of the single form: a modern interpretation of the traditional cabinet of curiosities."
