"Some of them wanted the playgrounds part underwater," Farrer Residents Association president Rollo Brett said.

While an underwater playground won't be getting off the ground, three new nature play spaces are, with Canberra children helping to design the final product.

The new playgrounds will be built in Glebe Park, Eddison Park and Farrer and will include natural play areas that include logs, boulders and creek beds.

Construction on the new spaces started on Tuesday and is set to be completed by September.

City Services Minister Chris Steel said the final design for the playgrounds were chosen with the help of primary school students.

"Children are the experts in their own play, and we've been consulting with them about designing the new spaces," Mr Steel said.

"We know children use elements in a way that adults don't understand ... and as a result there's some fantastic designs."

Among the elements used to boost interactive play are a sand and water area at Eddison Park, along with climbing mounds.

The new part of Glebe Park will feature rope courses, a tree house and creek beds with water pumps.

Mr Brett said the new space at Farrer, which will included timber climbing structures and climbing nets along with a mountain bike circuit, would be a great addition to the suburb.

"The kids are really looking forward to it, particularly the kids with bikes," Mr Brett said.

"People will be able to come down from school and go down into a community-built park.

"We wanted people to come over and let kids take risks and do the things that kids do.

Work is also set to begin on two more nature play spaces in the near future with funding announced for playgrounds at Kambah District Park and Yerrabi Pond.
