There is an application for the empty plot in Caroline Street. This has been empty for at least 30 years since a mysterious explosion and all previous applications have come to nothing.
This one is slightly different in that the owners of Wyndham Arcade appear to have bought the plot and are proposing to turn it into a courtyard whilst reconfiguring a couple of the units so that access can be gained from the arcade to the courtyard and vice versa.
If done well this could be really good with planting, decent lighting and seating, some street art on the walls of the adjacent buildings etc. It will also compliment the Brewery Quarter which has its Caroline Street access almost directly opposite. Application is at the link
