Wandsworth Council will go to court to evict a group of protesters from Battersea Park adventure playground.
Campaigners from Occupy London and Wandsworth Against Cuts (WAC) have been occupying the playground for more than a week in a bid to save it from demolition.
The council will be seeking an order of possession at the county court on Thursday, after the demolition was delayed for a second time today.
A spokesman for the council accused them of putting the upgrade plans at risk as well as creating a fire hazard.
He said: "The revamped playground is scheduled to reopen at the start of the Easter holidays so that children and young people in the area can enjoy the new facilities during the school break. The continuing presence of the squatters is jeopardising this timetable.
"They do not have any sanitary arrangements in place at the playground and have also lit fires near to the existing wooden structures. They do not have any fire fighting equipment if these get out of control nor do they have any fuel sources on site apart from trees and wooden play equipment."
The protesters have said they will continue their fight for the playground and have planned a rally to take place outside Wandsworth County Court on Thursday.
On Saturday about 70 people turned up to an event to celebrate a week of the occupation at the playground.
Labour councillor Sheila Boswell, play staff and parents gave talks to the public while banners were put up around the playground.
Wandsworth Labour Opposition Leader Rex Osborn said: "We are sympathetic to the aims of those occupying Battersea Park Adventure Playground - however we cannot and do not support any illegal activity in pursuing these goals.
"Just over the border in Lambeth, the council has shown there are different ways to achieve the savings that Wandsworth is chasing."
This morning campaigners continued their occupation despite the onset of snow and cold weather.
Johnny Remlap, 25, of Occupy London, said: "It is fine. It is cold but the warm wishes and generosity of the people in the community keeps us warm."
The case will be heard at Wandsworth County Court, Upper Richmond Road, on Thursday.
