Founded in 2004, Akb Architects is the Toronto-based residential architecture studio of Robert Kastelic and Kelly Buffey, architects dedicated to the practice and art of building. The quest to capture the poetic and ineffable qualities of space manifests in Akb’s design process, which prioritizes a clarity of vision, attention to detail, and a rigorous commitment to conceptual intent. The work of the studio benefits from Robert and Kelly’s extensive training in both architecture and interior design; a comprehensive strategy results in buildings of exceptional resolution and an uncommon level of refinement. A unified and holistic approach to interior and exterior space merges building and landscape into a seamless experience, transforming the ephemeral into the tactile.

Elements of volume, light, proportion and materiality are orchestrated to resonate and respond to each project’s unique site, context and program. Compelling in their tranquility and quiet simplicity, the resulting buildings are warmly engaging, elegant and functional. Akb recognizes the importance of a collaborative process in maintaining an open dialogue with their clients, ensuring all needs and desires are met. Meticulous research, precedent studies and the deployment of current sustainability strategies enable the studio to fuse the practical and the abstract in an architecture that is creative, inspired and enduring.
