HISTORICAL OFFICES BUILDING

The Longos mansion, also known as the Red House, is a three-storey
house in Agias Sofias Square in the center of Thessaloniki. An elevator
was designed and constructed in order to harmonize aesthetically with the
existing building, while at the same time the frescoes in the inner masonry
of the shaft and its roof had to be preserved, due to the historicity of the
building.
