TP Bennett said a greater quantity of retail space had been envisaged when it was commissioned to draw up expansion proposals for the department store in 2015, but House of Fraser’s plunge into administration last year had changed the plans.
Thank you. I did look on their site & didn't find anything specifically. Not too sure about the blg glass roof, but it's better than knocking down the building & starting again I suppose.
And yes, I don't suppose there will be as much need for retail space there now. Hopefully, any office space will be affordable and attractive to clients as there is already a lot of empty office space around the city centre, with more being built almost continually.
