The 1,800m 2, three-storey block will house the college's refectory, reception, multi-function hall and specialist teaching areas for hair and beauty salons.
The £3 million project, which is set to go on site next summer, is a key phase in the proposed 'centralisation' of the college's accommodation into one main campus on the edge of the Lake District.
Explaining the project, practice director Faheem Aftab said: 'The building will be of a steel frame construction, the sloped glazing will be a standard curtain walling system tipped to the maximum [angle] allowed without having to alter the standard specification.'
He added: 'The roof and curved walls and floors are proposed to be made from a standard composite board curtain walling system.'
The scheme is expected to be submitted for planning in January.
