The category B listed building which dates back to 1795 will be treated with a new lime-based render, replacing the cement which is in poor condition.

The repair works which start on Monday 12 August, will see the defective cement-based render removed and the sandstone prepared with a new lime-based render before being finished in breathable masonry paint.

Scaffolding will be erected around the tower as part of the works which means surrounding roads will be affected.

Councillor Martin Kilbride, Buildings, Housing and Environment Portfolio Holder for South Ayrshire Council said: “I am delighted these works are taking place. The use of the new lime-based render is much more in keeping with the original construction methods and is better for the stonework.

“The tower is an important part of Ayr’s history and is all that remains of the original tolbooth, so it should be preserved for future generations.

“Disruption will be kept to a minimum however it will be necessary to close a lane on surrounding roads to protect the public and ensure the contractor has a safe working area.”

An area of vegetation on the traffic island will also be removed to allow the installation of a site compound.

The works are set to finish this December.
