The £50m “Music Box” project for the BBC, designed by Foreign Office Architects, may be about to move forward after a six-month delay.

Farshid Moussavi, the head of Foreign Office, met senior BBC property staff last week to discuss the scheme, which was put on hold after a round of cost-cutting and redundancies at the corporation.

The BBC picked Foreign Office for the scheme, which will provide a home for the BBC’s orchestras and choirs.

However, the project has stood still for six months and observers feared that plans to move staff from White City, in west London, where the building is planned, could have jeopardised it further.

A source at Foreign Office said the scheme had been difficult for the BBC to support while it was shedding jobs and relocating so many staff.

The BBC has recently restructured its property partnership with Land Securities Trillium and is seeking a partner for facilities management and other specialist property services.

Foreign Office is working on the Ravensbourne College of Design and Communication in Greenwich, south-east London, near the Millennium Dome, and the Shires mixed-use scheme in Leicester.
