Residential Design and Construction Documentation Since 1999

Custom CADD provides residential design, permit drawings, construction documentation and technical support for homeowners, builders and design professionals across Ontario.

Built on Clear Drawings and Practical Residential Experience

Since 1999, Custom CADD has focused exclusively on residential design and construction documentation, contributing to more than 1,800 residential projects across Ontario. Over that time, we have worked alongside homeowners, builders, interior designers, engineers and municipalities on projects ranging from renovations and additions to large custom homes.

That experience shapes how we work: understand the project constraints early, develop the design carefully, and produce drawings that clearly communicate what is being proposed to the people responsible for approving, pricing and building it.

Experience That
Carries Through the Project

Residential projects involve more than design. Property conditions, zoning, building requirements, consultants, approvals, budget and construction all influence the final result. Our experience helps connect those considerations from the beginning, allowing design decisions to remain grounded in the realities of approvals and construction.

Residential Design

We develop custom homes, additions and renovations around the needs of the client while considering the property, budget, zoning, building requirements and practical realities of construction.

Technical Documentation

We prepare detailed permit, pricing and construction drawings that clearly communicate the project to municipalities, consultants, builders and trades.

Project Coordination

We work with builders, engineers, interior designers, municipal reviewers and other consultants to coordinate information and address technical requirements as the project develops.

Our Team

Custom CADD is intentionally hands-on. Design, technical development and project coordination remain closely connected, giving homeowners, builders, designers and consultants direct access to the people responsible for their project.

For Fully Integrated Custom Homes

Lamadeleine Design is our principal-led studio for a limited number of substantial custom homes requiring a fully integrated design process from early project strategy through construction.

These projects typically require a higher level of integration between home design, interiors, landscape, consultants and construction, with principal involvement maintained throughout the process.

Custom CADD continues to serve homeowners, builders and design professionals through flexible residential design, permit, construction drawing and technical support services.
