The building is simply referred to as Northumberland Road teaching accommodation and is temporary (for a little over 3 years, and may be longer) teaching space for the University of Sheffield Management School (see https://www.sheffield.ac.uk/efm/estatesdevelopment/projects/management-teaching). Maybe just Sheffield University Management School - the same label as the building on the corner of Crookesmoor Road and Conduit Road 150m to the NW.
