The blunder that has delayed construction of affordable homes in Scone should set the project back by just two weeks, according to the council.
Contractors built the flats 15cm too close to the road and 50cm too high, which means the project’s planning permission must be changed.
It was originally thought that the construction work could be set back several months while the paperwork was altered.
However, work is continuing and the amended planning permission is expected to be in place before the end of the month.
A spokesman for Perth and Kinross Council said: “A minor adjustment is required to the planning consent and this will delay the completion by no more than two weeks. Work will continue during that time.”
He added: “The council’s planning service has confirmed they are content to treat the proposed revisions as non-material changes from the approved plans.”
Perth and Kinross Council has set aside £4.7m to build affordable homes across the region, which now has the fastest growing population in Scotland.
It is hoped the development of 10 flats in Scone will help alleviate the housing shortage.
However, the delay prompted a political spat between the council’s former housing convener Peter Barrett and current incumbent Dave Doogan, who described the error as “in no way unprecedented in the construction industry”.
Councillor Barrett said: “Mr Doogan might be happy to suggest that these sort of blunders are par for the course, but I am absolutely astonished.
“I’ll bet anything that the people on the council’s housing waiting list don’t think much of his complacent response, either.”
Councillor Doogan responded: “I would like to point out that at no stage has Councillor Barrett ever sought to discuss this with me. However, in the very near future, tenants will have access to further first class affordable housing in Scone and, in my book, that is positive.”
