‘H50′ is an apartment block located in petralona – a low height building in the oldest district of athens. Built within an 118 m2 plot close to ‘Filopappou hill’ – a well-known archaeological park of the city – the two storey house contains a set of apartments, a roof garden and an open space situated at ground level. The concept was based on the idea of an monolithic structure, made from a single piece of stone such as marble. the aim was to expose and contrast the rough and smooth surfaces of the metamorphic rock through the sweeping triangular curves of the exterior.

The patios are mounted at the southeast side of the plot, where all of the apartments face the street. metal folding shades protect the courtyard and the rooms from the sun, as well as emphasizing the monolithic aspect of the block and the required privacy of the residents. Modular elements are embellished upon the design, inside and outside of the building, expressing a unified visual language. the irregular, yet complete form of the structure introduces a pure vision emphasized through the use of raw marble.


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.
