Whether you're planning a new custom-built home or new cottage, a spacious new addition, or a complete renovation, we are here to help transform your ideas into a well-designed, buildable reality.

At LJH Architectural Design, we specialize in custom residential design throughout Ontario—from fully custom homes and cottages to renovations and additions, garages, ADUs, and more. With nearly three decades of experience, we bring attention to detail, a deep understanding and responsibility to building requirements and architectural styles, and a strong respect for the story behind every home.

We work closely with you—starting with a conversation about your lifestyle, what matters most in and around your space, and what the final design should feel like. From there, we create a unique design that reflects your goals; and we will guide both you and the project through every phase:

Site analysis and zoning/by-law review
Concept design plans and 3D visualization
Revisions until you are completely satisfied
Permit-ready and construction-ready working drawings
Ongoing support during construction

We believe in intelligent and responsible design - homes that are thoughtfully planned, deeply personal, specified and built to support how you and your family live, every day.

Let’s start the conversation—there’s no pressure, just the beginning of something great.
