Oľga Ondreičková is one of the exceptional figures of the first generation of Slovak architects. Her work is characterized by pragmatism, simplicity, and monumentality. Her husband is architect Pavel Ondreička, with whom she collaborated on several projects, as well as on the design of furniture, interiors, and artistic decorations. At the height of her career, Oľga Ondreičková led her own project team, which was rare for a woman at that time.
