Plans for new homes on marshland in east London have been opposed by thousands of people living nearby.
A petition against the development in the Lea Valley has now got more than 4000 signatures.
Campaigners argue the new flats would damage an area which is home to grass snakes and hedgehogs.
Lee Valley Park who own the site told London Live that "no decisions have been made about selling any land". They went on to say:
"Waltham Forest's draft vision includes a location for a new venue to replace Lee Valley Ice Centre, which is reaching the end of its operational life, and designating a five acre site at the WaterWorks Centre for housing. There are around 500 acres of green corridor running north and south through the area. Money raised from any potential sale would go towards the Authority's plans for a new Ice Centre and for improvements to the green space in the area, which are also part of the vision. No decision has been made on whether to dispose of any Authority land."
