McLaren Construction is understood to be in pole position to overhaul and extend one of the first generation offices built at Canary Wharf in London Docklands.
The 25 Cabot Square building revamp is thought to be worth up to £45m and will see extensive changes to the office built in 1991.
Under the plan, the 390,000 sq ft building will be refurbished, with around 100,000 sq ft added through new steelwork extensions to the structure at 9th and 14th floor levels to create additional office space and new terraces. These will take the form of double height covered colonnades on the building envelope.
The proposals for the 16-storey building include significant works at plaza level to improve the entrance foyer and gym in the building basement.
Ramboll has been appointed by the client Hines providing structural engineering services for the refurbishment.
25 Cabot Square was built by Morgan Stanley who then billed developer, Olympia and York for the building. Unable to pay the cash they owed, it marked the beginning of the end for Olympia and York, the original Canary Wharf developer.
