The technical and visual renovation of River Estates office building located on Váci út was completed by the end of 2015. In terms of sustainability, the installation of the new HVAC system (heating, ventilation, air conditioning) is the most important part of the project, significantly improving the building’s energy features. By the end of 2015 the building had an occupancy rate of over 96% with new lease agreements for approximately 4,500 sqm of office space.
