The Birchwood Shopping Centre on Jasmin Road, Lincoln has officially reopened after a revamp worth £7 million.
Work to double the centre in size began in 2008, increasing the retail space from 37,000 sq ft to 73,000 sq ft.
New units were added, as well as 18 new one and two-bedroom flats, which were already snapped up.
As part of the official reopening, Lincolnshire Co-op President Julia Romney gave £250 donations to St Barnabas Hospice and other charities.
The centre had originally 27 units, of which 10 were demolished to make way for two larger units and the flats.
Most of the commercial space available has been taken up, with several units still available to let by businesses.
Improvements to the car park area were also made, and CCTV and better lighting were added.
The Birchwood Centre is owned by Lincolnshire Co-operative, who have funded the whole revamp project.
The shopping centre serves around 17,000 people in the area.
