Austin-Smith:Lord Architects has received planning approval for a new extension for the International Slavery Museum in Liverpool, UK.
The £6m ($8.6m) expansion will incorporate an adjacent grade I listed building, which will double its floorspace.
A separate entrance will be created while a new glass walkway will connect the two buildings.
The museum's original lightwell, running from the second floor to the top of the building, will be reinstated as part of the project.
The extension will be used as an exhibition space and will also serve as a media centre with education suites, staff areas and a café.
The development work is subject to funding and is expected to be complete in 2012, according to bdonline.co.uk.
