Renovations, additions and custom homes
For a home in Bridle Path-Sunnybrook-York Mills, the design conversation should include more than floor area. The position of the entrance, the outlook from principal rooms and the relationship between the house and landscape all influence how the property feels and functions.
Grand Design Build can help compare a major renovation or addition with a custom home. Use one clear brief for the rooms, privacy, outdoor living and features you want to retain, then assess the work each option would involve.

Local housing context / 2021
The City’s 2021 profile records 68.6% of dwellings as single-detached homes. The largest single original-construction period is 1960 or earlier, at 22.4%; it is not a majority of the housing stock. Later alterations and replacement homes still need their own property review.

The City’s replacement housing guidance for former North York considers the building and site together. Its discussion of landscaping, driveways, roof form and building mass is useful when preparing the design brief; applicable zoning still needs a separate address-level check.

Before the scope is fixed
Compare the entrance, driveway and garage with the front rooms and landscape. The North York replacement housing guidelines consider the visual prominence of garages and paved areas. Use that relationship to test the design rather than choosing the facade in isolation.
Mark the views you value and where neighbouring windows or outdoor areas face the property. Plan side and rear elevations with the same care as the front. Window locations, screening and room uses should be considered together as the house takes shape.
Record visible changes in level and existing trees before settling the footprint. Where a ravine or natural feature may be involved, check the City’s address map and proposed activities. Do not assume every property in the wider neighbourhood has the same constraints.
Use the same room schedule and finish priorities to compare an extensive renovation, an addition and a new build. Record what remains, what is removed and what must be investigated. Include external works and connections to the garden in the scope comparison.
For the property and proposal, the City’s preliminary zoning review information explains the available review routes.

Explore additions
Develop a custom home around the site, room schedule and landscape priorities. Coordinate the design and construction scope before work starts.
Explore custom homes
Assess a separate dwelling as a distinct site proposal. Review access, placement and the main house relationship before assuming a suite is feasible.
Explore laneway / garden suites
Coordinate the agreed work, project decisions and construction sequence. Record inclusions, responsibilities and changes as the design develops.
Explore project managementHow the work moves forward
Work through the property, scope and decisions before construction. Keep responsibilities and changes recorded as the project progresses.
Discuss your project

Start with what works, what does not and the changes that matter most to your household.
Assess the layout, structure and relevant site conditions before developing the renovation approach.
Coordinate the rooms, structural approach, services and finishes. Review inclusions, exclusions and responsibilities before construction.
Coordinate the drawings and applications required within the agreed scope, including a Committee of Adjustment application where needed. Allow for review comments and further information. The proposal identifies how City fees, Committee fees and survey costs are handled.
Sequence the work and trades around the project plan. Keep decisions and changes documented, with updates through the project coordinator.
Walk through the finished work, record outstanding items and agree the follow-up. Confirm the applicable closeout and warranty documents.
Planning questions
It depends on the existing building, the rooms you need and how the proposed home would use the site. Compare the structure and features worth retaining with the work required to change them. A large lot or a preferred exterior style does not by itself settle the renovation-versus-rebuild decision.
The City publishes replacement housing guidelines for the former City of North York covering building form, site layout and landscape. Confirm their relevance to the address alongside current zoning and any other property requirements. They are design guidance, not an approval for a particular building.
Include those changes in the initial brief. They affect how the home is approached and how outdoor space is used. Describe what you want to retain and review the proposed landscape and driveway work with the building, rather than leaving them as assumptions outside the scope.
The applicable boundary and proposed activity need to be checked by address. Use the City’s protection map and identify the work being considered, including grading or retaining structures. The review should establish the relevant requirements before the design is fixed.
Send the address, survey and existing plans if available, along with photographs and a short room brief. Note whether you are considering renovation, an addition or a custom build, and which parts of the house and landscape you particularly want to retain.
