Exploring if employees are returning back to the office and how the business clusters recover after the quarantine. Observations of people’s mobility before and after the quarantine highlight the crisis of the business centre’s traditional model – often being tied to transport corridors and not integrated into the surrounding context, they become highly inefficient during the economic crises, which opens the ground for the future discussion on the reconception, redevelopment and reinventing these areas. PwC and Habidatum conducted a joint study on changing key aspects of corporate work in the main business clusters of Moscow: City, Belorussky, Leningradsky and Paveletsky. These areas were analyzed in terms of: (1) Tennants' distribution by profiles; (2) Changes in the daily “life” of business areas: footfall, transactions dynamics, people’s activity in the cluster; (3) Assessment of potential vacancy rate volumes, resulting from the transition to new workweek schemes – a combination of office and remote (“home”) working days.
