The debate over the buildings has raged in the four years since the school's closure.
Hamilton City councillor Dave Macpherson said the swimming pool and gymnasium could be used by the community.
"There is a real shortage of those in Hamilton, especially out the west side."
Consent for demolition was granted in January following a four-day hearing, which looked at 880 submissions, in December.
Cr Macpherson said there is too little protection for heritage facilities in Hamilton.
"We chuck it away faster than anything and while I'm not a Mormon, when I was a kid [the college] was favoured back then, the Temple View village.
"It is part of our Hamilton heritage; it is not the LDS church's to chuck away as they please."
He said the Temple View Heritage Society has several ideas for the existing buildings, including a private high school or primary.
Ms McEwan said it is an uphill battle for heritage groups as most property owners don't stop to consider what they can do with what they already have.
"With any historic building you should do the very best you can to establish re-use. It should be this is what we've got, can we do what we want with what we've got.
"The problem is when you have a property owner who has, from day one, thought we've got a piece of land to develop as opposed to we have buildings, you starting from a position from a diametrically opposed view."
