Officers had to make good loose lead flashing on the turret of 18 Grand Parade during a survey to assess the condition of the building, which has been the subject of legal action over a number of years.
The Council has become increasingly concerned about the safety of the building at the junction of Grand Parade and Radford Road, and given its height, hired a cherry picker to carry out the inspection.
As well as the lead flashing, pieces of wood had to be nailed down and a number of the windows assessed as requiring urgent work.
The Council will now assess its findings, and will shortly contact the owners with some more essential repair requirements.
Councillor Brian Vincent, Cabinet Member for Planning and the Environment said: “For a long time we’ve been extremely concerned and frustrated about the very poor condition of this prominent sea front building and the negative impact this is having on the appearance of the area.
“Despite a number of legal actions, the property owner has failed to comply with improvement notices. Given the weather over the last few winters, we were concerned about its worsening state and so needed to see how safe it was.
“Quite a few of the neighbours who are extremely fed up with the appearance of this building told staff on site they appreciated the action being taken.”
The cherry-picker cost £450 for the hire period and the owner of the property will be invoiced for its use as well as Council officer time. A charge will be imposed on the property for these amounts if the owners don’t pay up.
The Council has the power to carry out works in default, and place charges on the property for the cost of the work involved, where prosecutions and fines prove to be ineffective.
