Oikonomakis Siampakoulis architects was founded in Athens in 2021 by Ilias Oikonomakis and Angelos Siampakoulis. The office works internationally in both private and public projects, ranging from residences and urban dwellings to cultural and civic buildings that are developed with a meticulous design process and a strong curatorial perspective. The built work of Oikonomakis Siampakoulis architect
s includes the remodeling of a multi-level parking garage in Athens city centre, and the renovation of an art curators' apartment in Lycabettus hill. Current projects include the restoration and extension of a stone family house in Athens, a new seaside home in Porto Cheli, the renovation of apartments in Athens, Ekali and Thessaloniki, the restoration of a 19th-century stone house in Crete, and a new private residential compound in Crete. The office is also engaged in public architecture through European competitions, with proposals for civic, educational, and cultural buildings. Each commission is approached as an opportunity to craft something unique with enduring character and artistic depth in direct dialogue with its context and its clients. The office’s approach draws on expressive sculptural forms, sharp geometrical clarity, and a refined orchestration of materials, resulting in works that are unconventional and meaningfully narrative. Its architecture language is both intellectually rigorous and sensorially immersive, drawing from varied cultural references filtered through a deeply conceptual process. The office operates with the care of an atelier and undertakes a small number of projects each year to ensure the highest level of attention and care. The founding architects lead each project and are directly involved in every phase, from conception to completion. Assigners are invited into a tailored and engaging creative process that is bound to the specific needs of each project. The practice has received international and domestic recognition in the architectural press, including features in Domus, Yatzer, Archdaily, Architizer, Designboom, Design Milk, Yellowtrace, ELLE DECOR Italia, and ΔΟΜΕΣ. In 2023, UK publication BUILD named the firm Greece’s ‘Best Emerging Architecture Office’, while in 2024 Architizer placed the practice among the top-10 architecture firms in Greece. The office's first built project “Parking garage with marble reception” has been awarded by GRAIL awards and BUILD magazine, and has received the 1st Prize for Best First Completed Work by a Young Architect by the Greek Architecture Awards.
