Nottingham City Council is preparing to tender for work to re-create a roof garden and remove Japanese knotweed as part of a £2.4 million shopping centre roof repair.
The council’s executive board agreed to spend the money on Tuesday to replace sections of the Victoria Shopping Centre roof covering, turf or plant the roof and eradicate the weed which is so far confined to planters.
According to the council the amount available for the roof garden work has not been decided but £30,000 is expected to be spent on knotweed removal.
The council is obliged to carry out the work as it holds a long-term lease.
Owner Intu Victoria Centre has asked that the council ensure the roof is watertight before spending £35 million revamping the centre.
The minutes for the meeting read: "The replacement of the roof will give comfort to Intu that their planned investment in the centre will not be undermined by any existing structural problems with the building.
"The work is essential to ensure the structural integrity of the building and to keep the roof in a well maintained state."
A spokesman for Nottingham City Homes which carries out the council’s obligations on the building said that a contractor for the knotweed work had been found but had decided not to carry it out.
He said there was no evidence the knotweed had spread to the roof or the rest of the building.
