Plans to demolish the former Grantham College building department have been submitted to district planners.
In its place, the College wants to erect 13 houses.
The site is to the north of The Barracks, Sandon Road, and opposite KGGS School. The building is now redundant.
The plans are for a pair of two bedroom homes, four three-bedroom houses and seven four bed dwellings, with parking.
The existing access will continue.
