The first Open House Worldwide (OHWW) takes place as a 48-hour broadcast of live and pre-recorded building tours, talks and discussions from the festival's website.

It features contributions from Open House organisations across six continents and 40 cities including London, Seoul, Mexico City and Melbourne.

The festival is organised into thematic sections which aim to address some of the issues facing urbanism and architecture today, including housing and climate change. The programme is divided into one hour slots and begins at midnight UTC.

Open House Worldwide takes place online from 14 to 15 November 2020.
