Designs for the new teaching facility in Ashford town centre include a central four-storey, circular entrance hall, featuring floor-to-ceiling windows, with two large building wings on each side.
To fund the £18m building cost, K College will sell its existing site at Jemmett Road in Ashford for housing.
Education bosses hope the relocation of a major college campus to the town centre, which could be in operation by spring 2013, will boost local businesses and the public transport sector.
