In 2008, Rintala started a new architect office with Icelandic architect Dagur Eggertsson, called Rintala Eggertsson Architects. The office is based in Oslo, South Norway and Bodo, North Norway.

Important part of Rintala's work is teaching and lecturing in various art and architecture universities. Teaching takes place usually in form of workshops where the students often are challenged to participate the shaping of human environment on a realistic 1:1 situation.

Sami Rintala's work is based on narrative and conceptualism. Resulting work is a layered interpretation of the physical, mental and poetic resources of the site.

Along with Dagur Eggertsson's professional practice, he has taught architecture in Norway, Iceland and Sweden. He is currently a project examinator at the Oslo School of Architecture.
