C-O lab is an architectural and construction office based in Athens and Serifos. It was founded in 2016 through the collaboration of Christos Siantrivanopoulos, a Surveyor Engineer and contractor, and Olga Ktenà, an Architect and Interior Designer. The projects we undertake vary in scale, from residences and small dining spaces to residential complexes and boutique hotels. Regardless of the scale of the project, our design values are functionality, innovation, simplicity, and attention to detail. In all our projects, our primary goal is to achieve a balance between comfort, intimacy, luxury, and respect for the landscape, tradition, and natural resources.
