The Spectrum Building opened in 1984. Its unconventional design using 'futuristic' steel frames and mirrored blue glass caused controversy, yet it was designed to blend in with the local skyline and literally reflect the Georgian landscape around it.

Problems soon occurred when the mirrored glass windows began to be stained from the heat of the sun. Steven Lubetkin, a chemistry lecturer from the University of Bristol, was called in to find a way of removing them.

Spectrum sits just south of Brunswick and Portland Squares, an area of St Paul's planned in the 1700s as a residential quarter for Bristol's prosperous classes. Over time, the wealthy professionals moved out to fashionable suburbs like Clifton and what had once been places to live gradually became places to work.
