The addition of a new building to the Athens Naval Hospital, which lies between Deinokratous Street and Lachitos Street, took place on the same plot of land that the existing hospital was on.

The eastern part was expanded and the addition was attached to the existing central building.

The addition connects the converging edges of the old wings along their eastern segments and was developed along the lines of the previous building, over six levels.

Patient wards, administration, first aid and auxiliary services remained in the old building.

The new building houses departments that require special design and infrastructure, such as operating rooms, an intensive care unit, radiotherapy, diagnostic departments, laboratories and regular outpatient units. 

Besides the attempt to ensure that proper operation continued, along with the particular nature of a military hospital, special attention was placed in dealing with building details both in the interior and on the exterior, in order to create a unified aesthetic result.
