Design Development

Design Development

You imagine the perfect home — we’ll design the plan to build it. At Big Ass Plans, we combine creativity with technical know-how to craft custom spaces that feel right and function flawlessly. Working alongside skilled surveyors and engineers, we make sure every square foot is not only beautiful, but buildable — with designs that meet local codes and match your lifestyle from day one.

Construction Documentation

Construction Documentation

Once your design is finalized, we turn it into a detailed, permit-ready drawing set. From site plans to floor plans, elevations, and schedules, everything is organized for clarity and compliance with Ontario’s building code. We provide the technical details your builder needs — and if the city requests changes, we’ll revise the drawings so your project stays on track.

Walk Your Plans

Walk Your Plans

Your dream home deserves more than just paper. With our life-size walkthroughs, you can walk your plans in real space — feeling every hallway, doorway, and room exactly as it will be. It's your chance to fine-tune the layout, test how it lives, and make changes before it’s too late.

Solutions For Every Project

You just need to see it.

Whether you're a homeowner building or renovating or an architect seeking stakeholder approvals on a commercial project, understanding the true size, scale, and flow of a space is essential before moving the project forward.

From Toronto to Muskoka and everywhere in between, we’ve worked with forward-thinking architects, designers, and builders to bring their designs to life for their clients.

Our collaborative visualization studio transforms designs into immersive, full-scale environments, helping validate ideas, refine layouts, and letting clients confidently take next steps.
