A popular pre-school could need about £100,000 to replace its crumbling 25-year-old mobile building - or risk having to close for good.
The nursery in Kenninghall, between Thetford and Diss, provides a vital service to working parents in the village, who might not otherwise have time to take their children elsewhere.
But it has spent its whole quarter of a century lifespan in the same mobile classroom in School Close, Kenninghall, which is less durable than a brick building and has long been showing signs of wear and tear.
'We are at a point where a survey has been done and it has not got a long shelf life left,' said pre-school chairman Heidi Glendenning.
'The scenario at the moment is that if the building were to fall down tomorrow, we'd be stuck. We have no other facilities to move the pre-school to.
'We have to stay open.'
South West Norfolk MP Elizabeth Truss visited the pre-school on Friday, January 12 to support the fundraising campaign.
Organisers say that replacing the current premises with another mobile classroom would cost £60,000 - but Mrs Glendenning said: 'We'd really like it not to be a mobile classroom.'
Mrs Glendenning said the pre-school desperately needs more space including a quiet zone and music area, adding: 'It's better for their learning. It's just a better environment for them.
'We'd like to offer more facilities but in a mobile classroom we just can't do that.'
Organisers estimate that they will need somewhere in the region of £100,000, although the final total will depend on where they can build as well as the size and type of building they go for.
'We're talking about various options,' said Mrs Glendenning.
'We're in the village and we're heavily relied on by parents round here. Some families share a car and can walk to the pre-school.
'It's really important for the village to keep the pre-school.'
Fundraisers will pursue grant money but said it is likely donations will also be needed from the public.
It also plans to hold fundraising events.
