I managed to get to 4 locations this year. Here are some of the images I managed to grab.
The head quarters for the London Mayor by the Thames and Tower Bridge.
Two Temple Place
Just by Temple Tube on the Thames Embankment – Two Temple Place was a mansion built as an office for William Waldorf Astor.
The Foreign & Commonwealth Office
In the heart of Whitehall – the home of the Foreign secretary.
Next to the Foreign Office – the office for the Chancellor of the Exchequer.
