A practice shaped
by place.

Founded by architect Markos Portalios, PRTA is an architectural and development studio rooted in the Mediterranean landscape.
After more than a decade working between architecture, permitting, and property development, PRTA was created as a new collaborative platform: a place where design, legislation, and construction meet.

The studio works with a close network of structural and MEP engineers, surveyors, contractors, and specialist consultants across Greece. Together, we design buildings that feel inevitable rather than imposed — quiet continuations of the places they inhabit, tailored to the people who live and invest in them.
