Home Renovations, Additions & Custom Builds in Casa Loma

In Toronto's Heritage Conservation Districts (Part V of the Ontario Heritage Act), any exterior work visible from the street — windows, doors, roofing, siding, or additions — requires a separate Heritage Alteration Permit in addition to a standard building permit. We prepare and submit these applications directly to the City's Heritage Preservation Services team, using the specific guidelines for each district (North and South Rosedale, Forest Hill, West Annex, and others). Minor changes are often approved in as little as one week at no extra application fee. Our team has deep experience with the exact district plans for these neighbourhoods, so we design additions and renovations that respect heritage character while delivering modern functionality. This means faster approvals and fewer revisions compared to contractors who treat heritage work as an afterthought. Your dedicated project manager coordinates both the heritage and building-permit streams so construction starts on schedule.

We provide fixed-price quotes, not estimates. Before any work begins, you receive a detailed quote covering the full agreed scope — materials, labour, permits, and project management. You only pay beyond that amount if you choose to add scope. This approach eliminates the surprise cost increases that are common with estimate-based contractors. Our fixed-price contract locks in the agreed scope, so there are no "surprise invoices" — a problem that over 50 completed projects have taught us to prevent through thorough pre-construction planning and transparent communication.

Timelines depend on project type: most bathroom renovations take 3–6 weeks, kitchen renovations 6–8 weeks, and basement finishes 4–8 weeks. Home additions and custom builds are scoped individually based on complexity. We provide a clear, detailed timeline before work starts and hold ourselves to it with our on-time completion guarantee.

The City of Toronto processes most renovation permits in 5–10 business days under the FASTRACK program for projects under 100 m². Larger additions, second-floor expansions, or custom builds typically take 4–8 weeks once drawings are complete. Projects needing minor variances through the Committee of Adjustment can extend to 3–6 months total due to public notice and appeal periods. Laneway and garden suites benefit from the City's new pre-approved plans, which can cut approval time significantly. We manage the entire process — application, drawings coordination, inspections, and follow-up — so you never have to visit City Hall. Your dedicated project manager provides a clear permit timeline at the consultation so you know exactly when construction can start.
