In March last year planning permission was granted for a new rear entrance, customer car park and apartment block at Smyth Patterson’s.
Since then a number of buildings have been demolished and foundations laid at the Wardsborough Road site.
Commenting on progress to date, Colin Patterson said: “We have really appreciated the co-operation and patience of staff and customers over the last few months.
“We are delighted our rear entrance is now open again and there is an area for customers to stop when leaving or collecting items. We hope to open a section of the car park early in 2019.”
With the next phase of the scheme due to start soon, the company are currently holding a renovation sale to clear excess stock.
