This was one of the best walking tours I ever did! Thanks to Evan it was a fantastic experience because he is highly passionate about the topic, genuinely cares about his guests, always happy to answer questions and really a wonderful tourguide! I would not only recommend his tour for someone, who wants to learn about Brutalism, but also wonders how people in London live (from a different view than many touristy walking tours, which cover the main sights in London) and how the use of buildings can change over time. Evan gives a lot of food for thoughts, so if you have time to walk with him, do so!
