The Blue Condominium of Exarcheia

The building actually consists of two independent six-floor buildings that are joined together at the top floor. Particular care was given to the design and construction of the common areas such as the two entry halls, concierge desks, corridors, staircases, laundry, and the meeting room on the top floor. The meeting room was later separated into seven new apartments, thus increasing their number from 32 to 39.[2] The original designs included a pool, but its construction was never completed. On the ground floor used to be the café "Floral".

It was an innovative and distinctive building of that era. When Le Corbusier visited it during the fourth congress of CIAM, he said that "it is very beautiful."

Through time, notable people have lived in the Blue Condominium such as Leonidas Kyrkos (politician), Renos Apostolidis (writer), Sofia Vembo (singer), Lili Zografou (writer and descendant of Dionysios Solomos), Dimitris Horn (actor), Alexis Minotis (actor), Katina Paxinou (actress), the owner Kostis Antanopoulos and his family, Fredy Germanos (journalist and author), Dimitris Myrat (orchestra director), Evaggelos Meimarakis (politician and speaker of the Greek Parliament).

During the Metaxas dictatorship and World War II the building housed the counterintelligence organization "Midas" and its staff officer Ioannis Tsigantes. During the Dekemvriana events, fighters of the Greek People's Liberation Army had attempted three times to blow up the building. The Blue Condominium can be seen in Greek films like The Jealous Cat (1956) and Stamatis and Gregoris (1962).[3]
