Grimshaw's much-criticised 'ellipse' extension for the Royal College of Art in London has been called in by the ODPM.
The future of the scheme, which faces opposition from local residents, DOCOMOMO, the Twentieth Century Society and the neighbouring Royal Albert Hall, will now be decided at a public inquiry later this year.
The project - which would see the demolition of H T CadburyBrown's existing building on the site - won planning permission from Westminster City Council last August.
But now the English Heritagebacked scheme also faces an anti-campaign organised by exmembers of the Greater London Council architecture department.
James Dunnett of DOCOMOMO said campaigners were delighted by the decision. 'We are really pleased there will be an opportunity for the special considerations of the site to be thought out, ' he added.
