More than 350 people had joined a group called Save Horsham Town Hall on social networking website Facebook late yesterday.

The council's planned $14-million redevelopment of the town hall has drawn criticism for car parking reasons and fears big-name musicians will not perform in Horsham because of a reduced seating capacity.

Group creator Tanya Kennett, of Horsham, said she wasn't surprised by the number of people who had signed up to save the town hall since Monday.

Mrs Kennett said she created the group so she could present an official petition to the council as a plea to stop the town hall redevelopment.

"Some people are not confident enough to write a submission to council. I believe, like many others, that the redevelopment will destroy our town," she said.

Mrs Kennett said she was surprised by some of the comments written on the Facebook page.

"Council aren't asking people what they want," she said.

Mrs Kennett said many people did not agree with the redevelopment because the capacity would be reduced by 50 per cent to 515 seats.

Lynton Brown, organiser of the 50 Years of Wimmera Rock festival, said the town hall redevelopment was dividing the community.

"Seeing 50 Years of Wimmera Rock with 800 people dancing away to their favourite bands of yesteryear was an amazing scene. The town hall is our showpiece. Sawyer Park's Soundshell just doesn't offer the same sort of event," he said.

Mr Brown said the council was not looking at the future needs of Horsham.

He said strict government guidelines on the redevelopment were restrictive and not adaptable to Horsham's community needs.

Mr Brown said his personal view was that a venue holding 1000 people, with ample parking, should be built next to the Wimmera River.

"If you're going to build something then it should go down by the river. There's plenty of car parking. Build some cafes and restaurants and utilise the biggest asset this town has," Mr Brown said.
