Fund-raising is under way to build a community classroom at Rocks Park Primary School that can be used by children from across Uckfield.
At the moment there is just a small shelter on the land but an outside classroom could be used by children visiting the school to take part in an annual cross-country run or to enjoy a nature trail at the school.
Marie Stepney, from the Friends of the School Association, who is heading the fund-raising campaign, said they would like to have a proper wooden framed building which could be used by children from all primary schools rather than just Rocks Park.
The target is to raise £10,000 for the project and the first activity planned is an Easter Bunny Hunt on Sunday, March 20, from 11am to 2pm.
All are welcome to attend and follow a Bunny Hunt Nature Trail (£2 per trail entry), take part in a giant bunny raffle and buy from a barbecue which will include vegetarian food. There will also be drinks and ice-creams and free colouring.
The venue will be Rocks Park Primary School.
