What Akb Architects does
Akb Architects (legal name Atelier Kastelic Buffey Inc.) is a Toronto-based residential architecture studio founded in 2004 by Robert Kastelic and Kelly Buffey. The firm specializes in custom high-end residential projects — cottages, primary residences, and renovations — primarily across Ontario's cottage country including Muskoka, Georgian Bay, and ski-resort areas, with select international commissions. Its service offering spans conceptual design, interior design, project management, and sustainable design innovation, with documented expertise in Passive House methodology, continuous cedar cladding detailing, and Shou Sugi Ban charred-timber applications.
The practice is structured around its two founding partners, who serve respectively as Creative Director and Technical Director and who are both OAA-registered architects and Fellows of the Royal Architectural Institute of Canada (FRAIC). The team of 1-10 includes a dedicated BIM Lead and, as of 2024, a formalized management layer comprising a CFO, Managing Director, and Communications Director. Revenue is generated through project-based professional service fees — typically a percentage of construction cost — paid by high-net-worth individual clients on a per-engagement basis; there is no recurring or subscription revenue stream. The studio's brand is reinforced by 30+ industry awards and 50+ editorial features in international design publications including Dezeen, Wallpaper*, Architectural Record, Dwell, and Azure.
