The coronavirus pandemic significantly affected office work. According to the Prague Research Forum, the share of vacant office space in the total supply in Prague increased from 6.98% at the end of 2020 to 7.6% in Q1 2021. The vacancy rate increased by 220 basis points year-on-year and reached the highest value since 2 quarter of 2017. However, not all office centers have struggled with the outflow of demand in recent months. At the time of the coronary crisis, both the landlords' approach to their tenants, who eventually got into trouble, and the famous ratio between quality and price played a key role. And in these respects, Class B offices often came out victorious. For example, Nagano Park, an administrative complex in Prague 3 - Třebešín, under the management of Geosan Development, recorded an increase in occupancy from 89.95% in February 2020 to the current 93.94%. New tenants include, for example, the state-subsidized organization Service Facilities for the Ministry of the Interior or Advande Labs.
