A planning application for the redevelopment of the Tate Britain gallery in London, UK, has been submitted by Caruso St John.
The scheme has received half of the £45m funding allocated to the remodelling and renovation of the visitor areas within the existing Grade II-listed building.
It will involve revamping the main entrance by creating a rotunda domed atrium at the centre along with a spiral staircase.
The practice will also build learning studios and public spaces beneath the entrance steps and around the gallery.
Nine galleries in the southern part of scheme will be reconstructed with new walls, roofs and reinforced floors, while new galleries will be built in the south-west quadrant.
Construction work will begin in 2011 and will be complete in 2013, according to architectsjournal.co.uk.
