It is intended to be a world-leading research facility that will house some of the UK’s greatest collections of historical, botanical and zoological samples. Millions of ancient mosaics and pieces of sculpture, rare plant specimens and fossil remnants will be taken from the British Museum, the Royal Botanical Gardens at Kew and the Natural History Museum (NHM) in London and rehoused at Reading University’s Thames Valley Science Park in Shinfield, Berkshire.

London’s ageing buildings, crumbling storage space, and soaring land prices mean a move beyond the M25 is the only realistic way to protect the capital’s swelling backroom collections of scientific and cultural treasures while improving researchers’ access to them, say senior museum staff. The total price-tag for the venture could top half a billion pounds.

But this vast rehousing project has not been universally welcomed. Indeed, it has proved to be highly controversial among some groups, with researchers denouncing the proposals as acts of “cultural and scientific vandalism”. Others have accused management at Kew and the NHM of bullying staff into accepting the plan to rehouse collections.
