Pavlos Chatziangelidis founded 314 architecture studio in 2004. He studied civil engineering in National Technical University of Athens 1996-2002 and architecture engineering in The University of Thessaly 2006-2012. In 2004 he acquired a Master of Arts degree in design. The name 314 of the studio, is inspired from the mathematic symbol π = 3,14 that is used to count the area of the circle. This reference is related to the philosophical dimension of the concept of the circle. The basic characteristic of his design beside the ecological, social and programmatic dimensions of the project, is the creation of a shell that urges the user to experience an abstraction.
