Big-name contractors have been put on notice that a scheme to redevelop the IBM building on London鈥檚 South Bank is up for grabs after plans were submitted for a makeover of the brutalist icon.

AHMM鈥橲 proposals will see two new storeys added to the building which was designed by the firm of National Theatre architect Denys Lasdun and completed in the mid-1980s.

Stanhope is developing the building on behalf of client, Wolfe Commercial Properties Southbank 鈥� owned by Dubai-based Easa Saleh Al Gurg Group.

好色先生TV understands the work has a price tag of between 拢150m and 拢200m with Stanhope expected to run a competition for the job rather than award a negotiated contract.

Firms expected to run the rule over the scheme include Multiplex, Balfour Beatty and Mace. Others also set to throw their hats into the ring include Skanska, Lendlease and Sir Robert McAlpine.

Work on the building, which sits between ITV鈥檚 London home and the National Theatre, will go out to tender once IBM has moved its staff out. It is not clear whether the firm will move back or look for new, permanent space elsewhere in the capital.

The client said AHMM鈥檚 proposals would deliver new public space to ease crowding on the embankment walk, while the building鈥檚 currently unused terrace areas will be opened up to provide amenity space for occupants.

Planning documents submitted to Lambeth council said more than 20,000sq m of new business-use space would be created as part of the proposals, which would see the building鈥檚 gross internal floorspace increase from just under 28,000sq m to more than 50,000sq m.

AHMM鈥檚 scheme includes enhancements to the ground floor of the existing building, which sits beside Lasdun鈥檚 National Theatre, along with new restaurants and cafes fronting Queens Walk and the river Thames.

Wolfe said workspace for 2,000 additional employees would be created, while the additional storeys would 鈥渞espect the brutalist architectural style of 鈥榮tratification鈥� and setting with the adjacent National Theatre鈥�. While the NT is listed at grade II*, the IBM building has only local recognition.

Others working on the job include consultant Exigere, Heyne Tillett Steel as structural engineer and Watkins Payne as M&E engineer. CBRE is planning consultant while Butler and Young is approved inspector.

Lambeth has listed a statutory expiry date for determining the application in early May but a longer timescale may have been agreed with the project team.

The proposals are open to public consultation until 5 March.

The IBM building, which is the firm鈥檚 European headquarters, was once owned by Alan Sugar, whose real estate arm Amsprop sold it to Saudi investors seven years ago in a deal understood to be worth around 拢120m.
