A group including film composer Hans Zimmer has unveiled its initial plans for revamping an iconic recording studio.

Last year, it was revealed that the composer was one of four people to have bought the BBC’s Maida Vale Studios in Delaware Road, which had been listed for sale at £10.5 million.

The partnership, which also includes chairmen of film studio Working Title Tim Bevan and Eric Fellner and Hans Zimmer’s long-time business partner Stefan Kofsky, have unveiled plans for the site ahead of an expected planning application to Westminster City Council.

Planned changes include creating new planting and seating areas outside the studios, and replacing the corrugated-metal roof.

Inside the building, three “state-of-the-art” music studios will be created, alongside composer suites and music rooms.

The plans commit to a “retrofit-first” approach to the development, ensuring that much of its existing fabric is retained to minimise carbon emissions from demolition.

Acoustic protections are proposed for the studios, to minimise noise being projected outside.

The group behind the development has promised that the renovated studios will be fully electric and will use energy-efficient lighting and services.

It is hoped that the proposed upgrades, which are expected to cost millions of pounds, will help create new jobs in an area that was recently designated the North Paddington Creative Enterprise Zone.

Maida Vale Studios is Grade II listed and features a distinctive Edwardian façade.

It was bought by the BBC in 1933 and witnessed major recordings by the likes of The Beatles, David Bowie and Dusty Springfield.

Following the sale of the studios, the BBC is now set to open new music studios in Stratford next year.
