The King’s Court and Carriage Hall scheme will transform the area between Floral Street and King Street, creating a new walkway passage between the shopping streets.
Kohn Pederson Fox Architects designed the 90,000 sq ft scheme, which will create a new public courtyard with eight new shops, two restaurants and 45 luxury flats.
New retail frontages on Floral Street including a new anchor store have been designed to draw visitors to the scheme.
The Grade II listed Carriage Hall building on the western end of Floral Street will be converted into a new flagship retail space with a covered courtyard.
The total development cost of the scheme, which has full planning, is expected to be in the order of £85-£90m.
Work will start this autumn and take up to three years to complete.
