The Tate Modern made a show on Tuesday of its new pyramid-like extension, which significantly adds to the London gallery's space and allows it to exhibit more contemporary art from around the world.

Works on display in the revamped art museum, which includes the new 10-storey Switch House, include a room full of human hair and car bumpers by Indian artist Sheela Gowda and Yayoi Kusama's The Passing Winter 2005 (left).

The New Tate Modern extension increases the size of the gallery, which was built in a former power station on the River Thames, by 60 per cent and will open to the public tomorrow following a £260 million (S$500 million) revamp.

Tate Modern said that its completely re-hung free collection features some 800 works by more than 300 artists, with half of the solo displays dedicated to women artists. New acquisitions such as a 1960s sculpture by Lebanon's Saloua Raouda Choucair add to works by artists such as Picasso and Henri Mattisse.

Like the main gallery, which opened in 2000 and attracts five million visitors a year, the 65m-high extension was designed by Swiss architecture firm Herzog & de Meuron.

Clad in a lattice of 336,000 bricks in a nod to the original power station's brickwork, the extension has a public viewing level offering 360-degree panoramic views of the British capital.
