Behind the Build: Leanne Tammaro & Adolphina Czyrsky - Design Theory

Design Theory is a Toronto-based interior design studio led by Leanne Tammaro and Adolphina Czyrsky, renowned for their exceptional work in transforming private residences and shared condo spaces. With a seamless blend of modern elegance and functional design, the duo creates spaces that balance beauty, practicality, and the unique needs of their clients.
Leanne and Adolphina first worked together at an interior design office before joining forces to establish Design Theory. Their combined expertise spans construction management, space planning, and creative vision, ensuring thoughtful and detail-oriented results. I first connected with them on an inspiring trip curated by Lutron Canada to Lutron's NYC studios.
Design Theory’s work has been featured in House & Home and Our Homes Magazine and has earned recognition from the Decorators & Designers Association of Canada. Whether revitalizing shared condo spaces or designing bespoke interiors, they deliver inspiring and enduring designs that elevate everyday living.
