SIX flats are being demolished on Market Street, Hoyland, to make way for five terrace houses.
Plans to scrap the flats were approved back in 2010 but work has just got underway.
A Barnsley Council spokeswoman said planning permission had now expired. She said: "The applicant will have to resubmit a planning application. The demolition works are still acceptable."
The applicant is working through Barnsley-based Hylo Design but the firm could not be contacted this week.
We have been at the heart of our community, every week, since 1858. The town and its people have changed dramatically since then but the Chronicle has been a constant.
It’s our belief that news should be available to everyone regardless of their circumstance. But we need a little helping hand to do so.
Production Editor, Ashley Ball, said: "In an ever changing media world, it’s important that news is reported correctly and without any hidden agenda.
Your support allows us to keep holding decision-makers to account and report on everything that happens in the town, good or bad, fairly."
