Supporters of a hall built to serve a mining community in south Wales are hoping to hear that it has won £2.5 in the final of the BBC Two series Restoration on Sunday night.
The Edwardian memorial hall needs £2.49m to be restored
Newbridge Institute and Memorial Hall - the Memo - in south Wales will compete against seven other buildings to win the prize money for renovation work.
The live Restoration final will feature reviews of the finalists and people are able to vote before the lines close at 2200 BST on Sunday.
Supporters of the Memo have been campaigning for votes and 15 volunteers have spent time in the National Eisteddfod in Newport canvassing visitors to the festival.
"We're hoping to get the largest possible support from Wales for the Memo," said Ron McCormick, one of the supporters.

"We have been giving out leaflets, post cards and stickers - in an attempt to gain support.
"After Cardigan castle failed to get into the final eight many have pledged their support," he said.
The campaigners have also been giving out leaflets in England - in Cheltenham, Birmingham and Manchester.
"We've had a good response there also," said Mr McCormick who was responsible for one of the Memo's websites.
On Sunday, 80 people from Newbridge will travel to Hampton Palace where the final takes place, stopping in service stations along the way to distribute more leaflets.
The votes cast in previous shows have not been carried forward so each building starts with a clean slate.

The Edwardian building defeated Llanfyllin Union workhouse and Cardigan Castle in the Welsh heat of the contest.
The Secretary of State for Wales Peter Hain has shown his backing for the Newbridge bid.
"We in Wales cherish our communities and the Newbridge Memo and 'Stute is a living reminder of a community based around our rich industrial heritage," he said.
"Winning this would be a fantastic boost for the Valleys and for Newbridge."
To be restored back to its former glory, the Memo needs £2.49m - exactly the amount on offer to the ultimate winner of the series.
In all, 21 buildings across the UK were featured in the series, which is presented by Griff Rhys Jones.
The winner last year was Manchester's Victoria Baths, which received £3m from the Heritage Lottery Fund.
