BAM Construct has won the £300m main construction contract after fighting off rivals Skanska and Carillion.
Designs from architect Allford Hall Monaghan Morris for the one million sq ft building have now been submitted to Camden Council.
If approved, work will start on site early in 2014 with completion scheduled for late 2016.
AHMM director Simon Allford said: “The architectural approach, which has taken inspiration from King’s Cross and St Pancras International railway stations, complements the local area’s strong industrial heritage and will be a building London can be proud of.”
Davis Langdon is acting as cost consultant on the project.
