In conversation with Rory Olcayto

Since its inception in 1992, Open House has grown to become London’s largest festival of architecture and design, with this year's instalment set to see 800 of the capital’s best buildings open their doors to the public. In this episode of the TANK podcast, Rory Olcayto, chief executive of Open City and Open House, speaks to Matthew Janney about the history of the event, the overlooked architecture of London’s outer-boroughs and some of the highlights of this year’s program.

This year’s Open House will run from 21–22 September.
