Hellenic Healthcare Group (HHG) is moving forward with the complete redevelopment of the historic hospital complex on Kifisias Avenue, which comprises the “Hygeia” and “Mitera” hospitals, aiming to establish a new and unified architectural identity.

In collaboration with the architectural firm Tsoukalas Architects, the buildings of Hygeia and Mitera hospitals are undergoing a comprehensive redesign. The surrounding 25,000-square-meter site will be transformed into a themed medical history park, accessible even to external visitors, with a therapeutic and educational character. On the side of the property adjacent to Kifisias Avenue, plans include the construction of a large underground parking facility.

According to the project timeline, all necessary studies will be completed and the required permits obtained within the year. Construction is scheduled to begin in early 2026, with completion expected around mid-2027. The total investment is projected to exceed €30 million.

Design Based on Principles of Sustainability

The project places strong emphasis on sustainability, incorporating energy-efficient systems such as a double-skin façade, the use of natural materials, and extensive photovoltaic installations. These elements will establish the complex as a model of sustainable hospital design.

At the heart of this vision—and of the unification of the two hospital facilities—is the “Hippocrates Walk”, a continuous 12,500-square-meter garden that features more than 200 species of aromatic and medicinal plants.

This space will function as both a therapeutic and educational park, offering walking paths, quiet viewing points, as well as stations for rest and learning. Its design aims to promote the physical and mental well-being of patients, visitors, and staff. By integrating the hospital complex with the natural landscape and the urban fabric, the site acquires a renewed identity, reinforcing its role as a landmark in the wider northern suburbs of Athens.

It is worth noting that Hygeia Hospital began operations in May 1975 (celebrating 50 years of service this year), while Mitera Hospital was established in April 1979. Both facilities were built on a 25,000-square-meter plot, making the area one of the most significant healthcare hubs in Athens.
