The Science Museum in London, UK, is to undergo a £100m modernisation.

Designed by Wilkinson Eyre Architects, the designs for the revamp are intended to match with wider plans for the South Kensington area, and will boast a new glass feature called the Beacon on the Exhibition Road façade is intended to "present an exciting new image of the Science Museum as a dynamic and engaging place to visit".

The museum will feature a new rooftop cosmology gallery called SkySpace and there will also be two other new galleries: Making Modern Communication - which will teach visitors about the technological transformations that have reshaped society since the 1830s - and Making Modern Science, which will focus on the "very essence of science" and shed light on theory, practice and ethics.

The existing Making Modern Flight and Making the Modern World galleries will be expanded and a new façade will also be built, with multiple entrances to ease congestion, as well as three new sets of lifts inside.

Professor Chris Rapley, director of the Science Museum, said: "As the Science Museum reaches 100 years we aim to celebrate the achievement of this great institution, while maintaining our focus on the future: the future of the Science Museum, and the future of Great Britain and the world."

The project is expected to be completed by 2014.
