Andrea, Smusesuse, Jacov, David, John, Lars, thank you very much for your comments.
Andrea, the photos from both sets were all handheld, around 1/56 at f3.2, ISO 3,200. Fuji X-T2, 16mm 1.4. Some were processed in Photo Ninja, some are SOOC jpegs.
David, I know what you mean about London!
John, I actually spent nearly 20 years working in Phase 11, or Exchange House to give it its post construction name. I was there for a retiree Christmas lunch. I was quite relaxed when I left, which maybe helped with the inspiration. It is very interesting that you were involved in the construction of some of the Broadgate buildings. It is a fine office complex. Here is a picture of Exhange House.
