Architect Zaha Hadid is buying the current Shad Thames home of the Design Museum, it has emerged.
The museum has been at Butlers Wharf since 1989, but is due to move to larger premises at the former Commonwealth Institute in Kensington in 2015.
The site is expected to be used as an archive for the Zaha Hadid Architects practice.
The Design Museum said that the building’s lease belonged to the Conran Foundation, who would gift the proceeds of the sale - thought to be in the region of £10 million - towards the construction costs of the new museum.
Director Deyan Sudjic said that while the organisation was sad to be leaving Shad Thames, the sale would leave it in the “best possible hands” and make a substantial contribution to the remodelling of the Commonwealth Centre.
Zaha Hadid said the acquisition would preserve the “significance” of the building.
“We look forward to the future use and occupation of the building,” she said.
An art gallery dedicated to science has launched its first exhibition after opening in September.
