Parents whose tots attend a Brighton pre-school are pinning their hopes on finding £90,000 for a new nursery building.
Leaders of the Kipling Lions Pre-School in Woodingdean are having to turn people away because their cramped base is full.
They have managed to get a pre-fabricated building which is double the size.
They have until next July to find the money if they want it to be ready by the start of the next school year.
Two groups of 22 children meet each morning at the pre-school in the grounds of Rudyard Kipling Primary School in Chalkland Rise.
The new building would also be on the school grounds but would cater for at least 60 children and would have an after-school club.
Lynne Ford, of Connell Drive, Woodingdean, said: "Having an after-school club there would make a huge difference.
"I'd know that my children had somewhere safe to go straight from school or during the holidays. Both Krista and Josh have loved their time at Kipling Lions."
Michelle Date, a member of staff at the pre-school, said: "We may be living in dreamland to think of raising £90,000 but we're lining up lots of events to help us get there."
One of the events will be a charity auction at Saltdean Football Club, off Coombe Vale, Saltdean, on October 19.
Anyone wanting to get involved can contact the pre-school on 01273 309352.
