Home Addition Process in Toronto & the GTA

Our Toronto home addition process follows a clear design-build structure. Each phase emphasizes coordination, code compliance, quality control, and efficient execution. Review each step here:

The first step is a simple phone consultation, followed up with an onsite meeting. We’ll discuss goals, requirements, budget expectations, and timelines. Our design team can also provide onsite hand sketches.

During the onsite assessments we’ll evaluate your home’s structure, utilities, site access, and property conditions. We’ll look at the property’s trees, gas lines, and electrical capacity to confirm the project’s feasibility.

Licensed and experienced architects and engineers will develop design-forward layouts and drawings. 3D renderings are also available when required. We assist with material choices, accompanying you to make selections and providing quality, cost-effective options.

We determine estimated costs based on drawings, materials, and project scope. We’ll review the final project package, including a detailed outline of inclusions, exclusions, timelines, and the project scope, before ordering materials.

We handle permits, zoning, and local authority approvals. You can feel confident knowing we make sure your project complies with codes, meets structural requirements, and adheres to municipal regulations before construction begins.

Construction involves controlled demolition, structural work, framing, and system installations. We’ll have a project manager onsite to coordinate schedules, monitor work, and act as your primary point of contact.

We’ll conduct a final walkthrough with you to check our workmanship and make sure you’re completely satisfied. We provide warranty coverage and schedule follow-up inspections after completion to support long-term durability.
