Heritage
Working Inside Rosedale’s Heritage Conservation Districts
Both North and South Rosedale are designated Heritage Conservation Districts. Check the property's district plan and any individual designation before developing alterations. Heritage requirements depend on the work and the protected attributes, not simply whether a change is visible from the street.
Good To Know
What a Rosedale Project Involves
For a Rosedale home, check the applicable designation and district plan before proposing alterations. Confirm the required heritage approval and supporting information with the City, then include that work in the project scope.
Most Rosedale homes are solid brick or brick and stone construction over 100 years old. Renovation work requires masons who understand lime mortar, original brick matching, structural lintels, and the specific failure modes of buildings this age.
Homes adjacent to the Rosedale Valley Ravine or Vale of Avoca often require Toronto and Region Conservation Authority (TRCA) review on top of City permits. We handle the submission and the back and forth.
Heritage rules typically require new windows to match the size, profile, and divided light pattern of the originals. Confirm heritage window specifications and supplier lead times before ordering.

Homeowner reviews
What homeowners say
Grand Design Build did a rear addition, second storey, and all our bathrooms on a house in the Beaches. March to September 2025. We were told end of September and moved back in the second week, so a bit ahead of schedule. Fixed price contract, and the final cost was exactly the contract number. That mattered a lot to us. We decided to change few items for bathrooms and kitchen halfway and there were no issues with the change orders, and the pricing was really fair even though a fixed contract was signed. There were no pushback. The office project coordinators and the site supervisor were really helpful the entire way through. They also kept the site tidy for six months straight and our neighbours never once complained. Respectful crew. Recommend them.
Allen and his team were a dream to work with. Truly an amazing experience and an incredible condo full renovation. The work was top notch and Allen was excellent to work with, respecting our ideas and desires and making our renovation dream a reality.
I had a really good experience working with Grand Design Build on my home renovation and rear addition project. Their team was professional, knowledgeable, and easy to work with throughout the process. They took the time to understand our needs, offered helpful suggestions along the way, and also provided complimentary interior design support, which was a great added value. They were responsive and attentive to questions as they came up, and the project stayed on track from start to finish. I would recommend Grand Design Build to anyone looking for a reliable custom build and design company in Toronto.

Frequently asked questions
Rosedale questions, answered
If the answer you need is not here, ask us on the call.
Is my Rosedale home protected under a Heritage Conservation District?
Both North and South Rosedale have designated Heritage Conservation Districts. Check the current district boundary, plan and any individual designation for your address. Confirm the proposed work with the City's heritage team rather than assuming the same requirements apply to every home.
Can I do a major renovation on a Rosedale heritage home?
Interior changes and rear additions may be possible, but they are not automatically unrestricted. Review the property's protected attributes, district plan, zoning and existing structure before developing a layout. Confirm which heritage and building approvals the actual proposal requires.
How does the ravine affect what I can build?
Check the exact property against TRCA's regulated-area mapping and the City's ravine information. If the proposed work requires review, establish the investigations and submissions before the design advances. Include the agreed coordination and any specialist work in the project scope.
What's involved in getting a Heritage Permit?
A Heritage Permit application requires detailed documentation of the existing home, the proposed work, the materials being used, and how the design relates to the surrounding streetscape. It’s reviewed by City staff at Heritage Preservation Services, and significant alterations may go to the Toronto Preservation Board for further input. We prepare the full application package, including the architectural drawings, material specifications, heritage impact assessment where required, and any precedent documentation that supports the proposed design. Confirm the review requirements and current timing with the authority handling the application.
How much does a full Rosedale renovation cost?
Costs in Rosedale vary considerably and depend on the specifics of your home and project. Square footage, the extent of structural work, heritage material requirements, and the level of finish all move the number meaningfully, and a renovation paired with a substantial rear addition typically lands higher than a standalone renovation. Heritage work in Rosedale also tends to run higher than comparable work in non heritage neighbourhoods, because of custom millwork, masonry restoration, original window replication, and the longer permitting timeline. Rather than quoting a range that may not apply to your project, the work is planned around the house after the property assessment, before construction begins.
