Our Proven 6-Phase Process
We believe building a home should be an exciting journey, not a source of stress. Our integrated design-build team has spent over 15 years perfecting a simple, 6-step process that keeps your project on track and on budget.
Phase 1 : Consultation
We begin with a strategic meeting to align your vision and goals with site feasibility. This includes a detailed feasibility study where we review Toronto zoning bylaws, lot coverage, and setback requirements for your specific property.
Phase 2 : Design and Permit
Our in-house architects and designers create your custom blueprints. We manage the entire City of Toronto application process, including architectural drawings, structural engineering, and navigating any required zoning variances.
Phase 3 : Cost Estimation
Transparency is core to our business. We produce a detailed, line-by-line budget and lock it into a Fixed-Price Contract before we break ground, shifting the budget risk from your shoulders to ours.
Phase 4 : Construction
With permits in hand, construction begins. Managed by a dedicated project coordinator, this phase covers everything from structural framing and mechanical systems to premium interior and exterior finishes.
Phase 5 : Inspection
Our team and municipal authorities conduct thorough inspections at every milestone. We ensure full compliance with the Ontario Building Code and project specifications, addressing every item on our “Grand” punch list.
Phase 6 : Completion and Handover
The moment your vision becomes a reality. We conduct a final walkthrough to ensure your total satisfaction and seamlessly transition the new home into your possession, all backed by our 7-Year Structural Guarantee.
