Wymondham High School hopes to build a new contemporary building in which to teach its sixth form students.
Plans have been submitted by Norfolk County Council on the school's behalf for a single storey, wood clad modular building with a footprint of 358sqm.
The building, which would be constructed on a vacant area of grass on the school's grounds, off Folly Road, will house four seminar rooms and one larger classroom, as well as an informal area for studying, an office and toilets.
Folding partition walls have also been incorporated into the design so the rooms can be opened up further if required.
The planning documents said: 'The proposed facility will be primarily used for the teaching of the school's sixth form students who are currently taught in cramped accommodation located in various dislocated areas of the school.
'The new building provides sixth form students with their own space which offers a new, comfortable and business like environment and a distinct identity.'
The school currently teaches 1,620 students aged 11 to 18.
