She is the founder of AKK Architects, a multidisciplinary firm with projects spanning Europe, the Middle East, and North Africa. Kassar’s work is characterized by a deep sensitivity to historical and cultural contexts, often blending traditional craftsmanship with contemporary design elements.

Her projects range from large-scale urban developments to intimate residential and commercial spaces, always prioritizing materiality, texture, and sensory experience. In Beirut, she has played a significant role in preserving and reinterpreting architectural heritage, integrating historical elements with modern interventions to create dynamic, evolving spaces.

Beyond architecture, Kassar has also gained recognition for her large-scale installations, such as Salon Beyrouth at the Venice Architecture Biennale, which explore themes of memory, identity, and urban transformation. Through her work, she continuously challenges conventional design boundaries, creating environments that are both visually compelling and deeply rooted in cultural narratives.
