It could be a tough ask renting the office space out. Probably will depend on the cost per sq ft. Most office occupiers want to be in the city centre, not a few miles from it next to a football stadium. Metrolink, and parking, which will have to be provided, will help.
I went on a tour of Eden just over the city centre border in Salford. The agent told me they still had 7 floors to let, and were struggling to let the floor space as Eden wasn’t on the Manchester side of the city centre.
I’m sure overtime the office space will be let. The 3 floors aren’t big floor plates.
