Transport for London today announced TateHindle as the winners of the competition to transform their London Underground Headquarters into a residential building. The building, designed by Charles Holden and completed in 1929, was once the tallest office block in London and has been home to Transport for London ever since. However, TfL say the building at 55 Broadway is "no longer fit for purpose", and will move out in 2015 when TateHindle will begin the renovation.
