IT may not be the most picturesque building in the country but the Bawdsey Transmitter Block has captured the imagination of the nation and reached the final of television series Restoration.

The structure, which was integral to the production of radar and consequently played a pivotal role in the Second World War, was named the best runner-up in the BBC Two series after reaping in the public's votes.

It has joined the winners of the seven regional areas as the eighth finalist in the programme, which is dedicated to the rescue of the country's heritage, and the lines are now open for the ultimate national vote.

People have until Sunday night to register their support for the Bawdsey Transmitter Block and push it to the winning spot, securing its future with the funds raised during the series – including £2.5million set aside by the Heritage Lottery Fund.

All the finalists have started with no votes in the concluding national vote, and the number to vote for the Bawdsey Transmitter Block is 09011 322208. A minimum of 35p of every 50p call goes directly to the Restoration fund with lines closing at 10pm tomorrow.

n Today the Transmitter Block will be open from 11am to 4pm in an event run in conjunction with the BBC.

There will be exhibitions in the transmitter hall and Roger Thomas, military support officer for English Heritage, will be giving talks about the history of radar and Bawdsey at 12pm and 2pm. There will also be a barbecue run by the Woodbridge Air Cadets.
