I believe that Lidl are expanding the shop (bakery section), encroaching onto the existing carpark, hence needing more space for carparking.
They actually wanted the whole row of shops, from the hairdressers through to the Led light shop around the corner on Avenue Road. The chemist refused to sell, the dentist considered it but couldn't find alternative premises and our landlord sold us to Lidl (Party shop, Hairdressers)
If Lidl hadn't bought the buildings then I know that both businesses would still be in situ. Both have relocated, one further up Sheffield Road, and one (us) have merged into their larger shop in the town centre.
