Transport for London has pre-let a building in Stratford’s new £2.1billion International Quarter.

Construction will begin in the summer on the 265,000 sq ft building in London’s news commercial district, a joint venture by Lend Lease and London and Continental Railways (LCR).

An estimated 3,000 TfL workers will relocate to the International Quarter, part of the 25,000 people who will work and visit the site each day.

Work is already underway on the first phase of The International Quarter, at the gateway to the Queen Elizabeth Olympic Park. A 333-unit residential development named Glasshouse Gardens overlooks the Aquatics Centre, the former Olympic Stadium and ArcelorMittal Orbit.

Lend Lease COO Dan Labbad said: “Securing TfL as a major pre-let marks the emergence of a new generation of offices in east London that will make a lasting contribution to the local economy.”

Managing director of finance at TfL Steve Allen said: “We are consolidating our office accommodation into a smaller number of larger buildings. The International Quarter in Stratford provides the ideal opportunity for us to make further progress with its excellent transport links while enabling us to achieve significant savings.”
