Virtual plans for a new post-16 campus at Les Ozouets have been published by Education, Sport and Culture.
The 'fly-through' video shows what the future £100m campus will look like.
Work on its construction is subject to the States agreeing to release the money at a debate in October to agree which capital projects will go ahead and how they will be paid for in the face of a growing deficit in the island's public finances.
ESC says the bulk of the cost will go on specialist facilities needed for the professional, vocational and technical courses run by the Guernsey Institiute.
Around 20% of the total cost is for building the new Sixth Form Centre.
ESC President Deputy Andrea Dudley-Owen says the video shows the committee's 'ambitious vision for post-16 education'.
"The campus will herald a change in the way the community views and values both academic and technical, vocational and professional pathways. Dispensing with some elitism thathas surrounded post-16 education pathways, allows all learners to integrate via shared spaces such as a library and learning centre, refectory and outdoor seating spaces, regardless of their chosen area of study or training on one shared campus, in either The Guernsey Institute or Sixth Form Centre.
Learners from different study pathways will also benefit from sharing specialist areas like sports facilities, workshops, science labs and performing arts studios, encouraging collaboration."
Defending plans for the sports facilities - which include a four-court full-sized sports hall and spectator area - Deputy Dudley-Owen says they are justified because of the 900 students who will be using them.
"The new facilities will enable Guernsey to offer on-island sports degrees and a wider variety of professional sports fixtures."
She says the island needs ' support the ambitions of our young people and the economy' and to get on with the 'long overdue' investment in post-16 education.
