In October 1988, the Summaries moved with the Nine O'Clock News and Weekend News to the new larger newsroom set that was located where Studio N3 had been (whether this was located near the original newsroom set is unclear).

I was under the impression that the same newsroom studio was used in both instances - but that it was enlarged when the Nine and Weekend moved.

If you look at the behind this scenes video, the corridor and entrance from which Terry Wogan walks at the start looks to be the same as the one in the first screen grab from Newsroom Revolution. When Michael Buerk goes on set to prepare for the bulletin, it to be the same area but has been expanded (8:15 in on the video).
