It is part of the next stage in improving the play areas at Ferry Meadows, which has also seen the introduction of Otter Play in 2014 and Badger Play in 2016.
The play area will have water features, zip lines, raised walkways, climbing opportunities and new tree planting, with the aim of being the biggest of all the play areas and aimed at slightly older children, while remaining accessible to a range of ages.
The design, developed by architects Davies White, covers a 7,800 sq m area and will include 13 different pieces of play equipment incorporating water, sand, stone and wood.
22 new trees of five different species will be planted at the area, with 1,574 additional plants of 17 different species benefitting local wildlife.
FCC Communities Foundation and Viridor Credits Environmental Company has supported funding into the project among others for the area.
Cheryl Raynor, grant manager at FCC Communities Foundation, said: "We are delighted to be supporting the trust to enhance the Park.
"It is a fantastic facility for local people and we look forward to work starting shortly."
Gareth Williams, operations manaeger at Viridor Credits, said: "Nene Park Trust's vision for the park will create a wonderful, inclusive space for every member of the community.
"We are proud to be a part of that vision."
Head of development at Nene Park Trust Andrew MacDermott said he was "thrilled to see our plans become a reality".
Visitors are encouraged to use Coney and Oak meadows for picnics while the area for Fox Play is fenced off. The fixed BBQ stands that were positioned in the area have been moved closer to Lynch Lake and the other BBQ stands are located around Ferry Meadows.
Construction of the play area should be complete later in the summer.
