About Cadaxx Design

Toronto Architectural Design & Planning Services 
​
Founded in 2009, Cadaxx Design has grown into one of the most recognized and trusted names in architectural design and planning services in Toronto and the Greater Toronto Area (GTA). What began as a small studio focused on residential projects has evolved into a multidisciplinary design firm known for its innovation, precision, and practical solutions. Over the past decade, we've helped hundreds of homeowners, builders, and developers transform their vision into reality—through thoughtful design and thorough permit-ready documentation.
At Cadaxx Design, we specialize in custom home design, multi-unit residential developments, major home renovations, and additions. Our team brings together creative vision, architectural expertise, and a deep understanding of municipal zoning bylaws, Ontario Building Code compliance, and permit processes. This combination allows us to deliver fully compliant drawing packages that simplify city approvals and set the stage for smooth construction.
Our design approach is rooted in functionality, aesthetics, and code compliance, ensuring every space we create serves the lifestyle and goals of its users. From early feasibility studies to final construction drawings, we work closely with our clients to create designs that are both inspirational and buildable. Whether you're building a new custom home, adding a second story, converting a duplex, or planning a full interior renovation, Cadaxx Design offers the insight and support needed to get your project approved and moving forward.
As a proudly Toronto-based firm, we’re deeply familiar with local architectural trends, building regulations, and permit requirements. Our collaborative process ensures that clients receive not only expert drawings, but also clear communication and step-by-step guidance throughout the design and permit journey.
