Interiors of the European Medical Center were developed by the ABD architects Department of Interior where the chief architect was Maria Korneeva, who already had experience in designing interiors for medical centers, such as «Clinic 31». The authors sought to enrich the traditional for hospitals white palette using color and light accents. The bright green reception desk became the predominant detail of the entrance area and the ceiling of long corridors were painted with a cheerful yellow. In the corridors the single line of ceiling lights is hidden deep in the niche, making them unobtrusive, and the space is illuminated as a result of white walls reflecting their light.
The hallmark of the project became the innovative lighting solution for the «psychological relief room». It is located on the -1 floor and is devoid of any windows, so to compensate for the absence of natural light the architects came up with lighting on the walls behind the special-order panels. For a psychological emphasis the ceiling has integrated lighting inserts in the form of uneven spreading spots. Wittily hinting at the Rorschach’s famous psychological test (involving interpretation of various types of ink blots) the «spots» don’t only fill the room with light, but also visually make it more spacious and comfortable.
