Bam Construct has been awarded the contract to redevelop the Western Transit Shed as part of the £2 billion overhaul of Kings Cross being led by developer Argent.
Argent director Tony Giddings told Construction News that Bam had been selected to covert the 9,000 sqm shed into office and retail space, a job worth up to £24 million.
The site sits alongside the recently completed Granary Complex - occupied by University of the Arts London - and is due to be opened in October.
Argent has agreed a 15-year lease for the property with Hoare Lea where it will relocate its 165 strong London office.
The engineering firm will take 22,000 sq ft in the shed in time to celebrate its 150th anniversary in 2012.
It marks the eighth commercial agreement signed at Kings Cross, following deals with BNP Paribas Real Estate and Camden Council.
Structural engineer B&K has already carried out the installation of over 200 tonnes of structural steel within the shed.
Argent has developed lose agreements with Bam Construct and sister company Bam Nuttal to carry out extensive works on the 67 acre site.
