The BBC is seeking expressions of interest for a redevelopment of its Maida Vale studios in London worth up to £40m.
The existing studio building requires major investment to bring it up to a modern standard and the BBC is plotting a revamp worth between £15m and £40m.
Its studios are expected to be turned into a mixed-use residential and studio development on the site.
The BBC will fit out the interior of the building including the studios and ancillary office areas including the provision of studio facilities on a new site.
Built in 1909, the building was acquired by the BBC in the early 1930s to meet public demand for broadcasting.
It is now home to the BBC Symphony Orchestra, the BBC Singers, the Radio 1 Live Lounge and In Session recordings.
The BBC is looking to achieve a rating of BREEAM Very Good with an aspiration for BREEAM Excellent.
It is working with commercial property consultants Lambert Smith Hampton to seek innovative outline proposals for the 0.54 ha (1.33 acre) freehold site.
Further queries for the project should be directed to Lambert Smith Hampton: David Bianco and Peter Day on 020 7198 2290 or visit www.bbc.bravosolution.co.uk.
