Deloitte, Taylor Wessing and Mishcon de Reya are among top City firms joining forces with Chabad-Lubavitch UK to bring a large succah to the New Street Square development in Chancery Lane.
Part of Deloitte's Diversity Week, the succah will be available for use throughout the festival.
"Succot is about celebration of unity - how as a human race we all depend on the same divine protection," explained Chabad's Rabbi Bentzi Sudak.
