This year's Thomas Sutton Lecture is an online presentation by architect Eric Parry.

The lecture which is titled Boundaries in Time, Place and Material is a sequel to the lecture he gave last year for the London Festival of Architecture that explored the theme of boundaries. This year, Parry focuses on the social and architectural intentions behind the Revealing the Charterhouse project, which was a conservation and restoration project to remodel the Charterhouse in central London to house a new museum.

The Thomas Sutton Lecture takes place online on 26 November 2020.
