Munárriz' artistic work focuses on understanding and questioning urban space. He is interested in how citizens contront the surrounding environment, always questioning the links between artificial spatial creation and rejection, where "artificial" is synonym for "planned". Therefore, he compares artificiality with the accidental construction and deconstruction of urban space.

His clearly spatial and sculptural works focus on the relationship that visitors establish between art and their own reality as citizens, that is, Munárriz tries to interfere in the relationship between visitors and their environment by interpreting all spatial elements involved.

Munárriz has a BA in Fine Arts from UCM (Madrid). He also studied at the ABK in Stuttgart (Germany), SAIC (USA), USP (Brazil) and FAAP (Brazil), where he received a postgraduate degree.
