One of the investment categories with the strongest prospects in the real estate market is the development of environmentally friendly office buildings, whether they are new constructions or conversions of existing, older buildings.

According to research data, “green” offices currently constitute only 12% of the total office stock in Greater Athens, or 600,000 square meters out of a total of 5.1 million sq.m.

They therefore show zero availability, as new developments and reconstructions cannot meet the increased demand. This is also reflected in rents, which, according to Trastor, rose 6.5% on an annual basis in 2025.
