London’s Science museum has set a November deadline for architects to submit plans for its latest development as part of its ongoing five-year £60m (US$93m, €83m) transformation.

In 2015, Zaha Hadid and Muf were awarded separate contracts to redevelop the museum’s Maths Gallery and Interactive Gallery respectively. Now the museum is seeking a world-class architect to work on it Exhibition Road entrance, which will welcome more than 3.3 million people come through its doors every year.

The 1,200 sq m (12,900sq ft) area of public space, which the Science Museum has taken over from the Royal Mail, was earmarked for development following the museum’s purchase of the Post Office building on the north east corner of the site in South Kensington.

The entire Exhibition Road site runs from Hyde Park to South Kensington and has undergone significant development in recent times, most notably the new entrance being built for the nearby V&A Museum. The outdoor site was developed in 2011 at a cost of £28m and doesn’t have kerbs or pavements, with signs, traffic signals and barriers removed to form a “clutter-free” street.

The Science Museum’s masterplan will transform around a third of the world-renowned institution over the next five years. Currently in the first stage, the £60m figure has been raised through a combination of generous donations and grants from the Heritage Lottery Fund (HLF).

The museum has set a deadline of 2 November for the redevelopment of the Exhibition Road entrance, accepting submission from the website www.mytenders.org.
