Open House London: My top 25

Every year, Open House London offers rare access to a huge number of London buildings that are usually off-limits to the general public. Over the last few years, I have thus visited over 50 fascinating sites.
This is my countdown of the top 25 that I've visited to date. All of those featured are participating again this year (2017), although some require pre-booking (full list shown at end of video).
