The Hellenic Motor Museum is a unique cultural landmark in the heart of Athens, the vision and life's work of the late Theodoros N. Charagkionis (1948–2023), entrepreneur and lifelong passionate of the automobile. Housed in a architecturally distinctive building with a total built area of 30,000 sq.m., the museum is home to more than 110 exhibits spanning a century of automotive history, located just steps away from the National Archaeological Museum. We undertook the building envelope using a standing seam system, contributing to the aesthetic and functional completion of a project that stands as a lasting tribute to its founder's vision and dedication.
