Olga Mantzou
Architect Illustrator
I am a licensed architect based in Thessaloniki, Greece.
For more than 15 years, I’ve worked across multiple scales, from private residential projects to public sector projects (urban parks, schools, nurseries, and public spaces), always guided by a deep curiosity about how architecture shapes everyday life.
Over the years, I have built strong skills in project management, sustainable design, and team coordination.
My academic background includes an MArch in Architectural Engineering and an MS in Spatial Planning from Aristotle University of Thessaloniki, with a focus on sustainable and resilient development. This allows me to combine technical precision with creative, people-centered design solutions.
My practice moves between structure and expression. I’m drawn to clean lines, thoughtful proportions, and spatial narratives that feel intentional and emotionally resonant. Illustration is a key part of my process — a way to transform ideas into atmospheres and reveal the character and poetry within each project.
I am open to collaborations in architectural design, 3D visualization, and artistic illustration, both in Greece and across Europe. I also collaborate with architectural and civil engineering offices, as well as contractors, supporting them with design development, technical drawings, and 3D visualizations.
If you’re looking for work that blends conceptual clarity, technical understanding, and artistic sensibility, I’d be happy to connect.
