In the heart of Greece’s largest office building 

Over 1,000 employees bring life to the renowned “Kerani building,” which had been “soulless” for more than 15 years. It is a minimal building, with a surface area of 40,000sqm, constructed according to European standards. The impressive main entrance with its vaulted atrium and lawn is particularly striking. 

With an on-site technical maintenance team consisting of electricians, plumbers, and general maintenance technicians, headed by an engineer, UNISON covers the needs of the building on a daily basis, while also providing preventive maintenance of electrical and mechanical equipment.
