Offers Custom Work
Greater Toronto Area Custom Home Designers
Custom CADD Inc. is an Ontario-based residential design and construction documentation firm specializing in custom homes, renovations, additions, and drawing packages that are clear, detailed, and practical to build from. For over 25 years, we have helped homeowners, builders, and consultants bring projects to life through thoughtful design, strong technical coordination, and a process that feels straightforward and approachable. Our work ranges from renovations and additions to large custom homes, waterfront properties, and estate residences. What sets us apart is the balance between design and constructability. We focus on creating homes that feel right to live in, look resolved from the outside, and are coordinated thoroughly enough to reduce guesswork, site confusion, and unnecessary revisions during construction. Clients also value the way we work. We are known for being responsive, down to earth, and easy to talk to. We believe good design should feel collaborative and well guided, not intimidating. Our goal on every project is simple: deliver a well-designed home and a clear, coordinated set of drawings that helps it get built efficiently.

Frequently Asked Questions

Yes. We assist with zoning reviews, building permit applications and coordination with municipalities and other approval agencies. We identify regulatory requirements early, prepare permit drawings, respond to review comments and coordinate with consultants where required. For more complex properties, this may include conservation authorities, septic, grading, engineering and other site-specific approvals.

We design across a wide range of architectural styles, from traditional and European-inspired homes to contemporary and modern designs. Rather than imposing a signature style, we focus on creating homes that suit the client, the property and the surrounding context. Our strength is translating each client’s vision into a cohesive, well-resolved and buildable design.

Absolutely. We’re happy to work with the builder you select and regularly collaborate with builders throughout the design and construction process. If you haven’t chosen a builder, we can also recommend experienced contractors we’ve worked with successfully. Our priority is assembling the right team for your project, not limiting you to a specific builder.

We specialize in custom homes, cottages, major renovations and additions, from smaller residential projects to large, complex homes. Our work includes new construction, whole-home transformations, second-storey additions, garages, accessory buildings and challenging properties requiring detailed zoning, permitting or consultant coordination.

Yes. Every custom home we design is developed specifically for the client, the property and the way they want to live. We do not rely on stock plans or predetermined layouts. Each project is shaped by the site, zoning, budget, architectural direction and functional requirements to create a home that is both highly personal and practical to build.
