Traders in Mayo's county town, Castlebar, are unhappy with a market square development in the centre.
The £1 million project, which is almost completed, includes new paving stones, a new monument, raised flower boxes and new kerbing in the town centre.
A number of loading areas and about a dozen car-parking spaces have also been included in the design.
However, the chairman of the Town Traders' Association, pharmacist Mr John Durkin, says the new square is not what traders have spent 15 years designing in consultation with Castlebar Urban Council.
"In 1986 we began talking to the council about a proposed enhancement of the market square. Eventually, four years ago, ourselves, local residents, elected councillors and council officials agreed on a design. Work began on the market square about four months ago. It is now almost complete and it certainly is nothing like what we all agreed on," Mr Durkin said.
"We met the council at a special meeting this week in the council offices. We're not prepared to accept what has happened.
"The new square is at different levels, steps have been incorporated into the design, the new loading areas are too small and businesses are losing out because of the design," he said.
The assistant county manager for Mayo, Mr Alex Fleming, insists that there is no material difference in the now almost completed square from the maps originally agreed on by all sides.
"We would have no reason to make any substantial changes other than the alterations that we had to incorporate to meet health and safety rules", Mr Fleming said.
An Independent councillor on the authority, Mr Frank Durkin, said the present work should be bulldozed over and the wishes of the people living and using the market square implemented instead.
"I'd describe the new town square as an obstacle course, unsuitable for the elderly and people with disabilities. It's all at different levels," he said.
