Naya Kostarelou was born in Athens and studied architecture at the university "Ecole Superieure Nationale d'Architecture de Paris Belleville". She graduated in 2008. She has been working for architectural offices since 2005, at first in Paris simultaneously with her studies and later on in Athens where she is still working as a freelance architect.

Her collaborations have given her the opportunity to gain experience in all the phases of architectural projects from preliminary studies to construction drawings. She has also participated in architectural competitions.
Her interest in art and theatre led her to take acting lessons. In her opinion acting as well as Architecture are both a form of expression and the exploration of human existence that helps us understand society and its needs.
