Custom Homes & Renovations in Forest Hill
Custom Home Builder in Forest Hill
Georgian and Tudor estates, mature streets, and heritage-sensitive design. Grand Design Build has worked in Forest Hill and across midtown Toronto since 2010.
Forest Hill is one of Toronto’s most established neighbourhoods, with Georgian and Tudor estates, mature streets, and a housing stock that’s defined the area for nearly a century. Building or renovating here is rarely straightforward, most projects involve heritage considerations, careful design that respects the streetscape, and the kind of craftsmanship that lasts as long as the homes already do.
Grand Design Build has been working in Forest Hill and across midtown Toronto since 2010, and every project we take on comes with a fixed-price contract, full HCRA licensing, and a 7-year structural guarantee written into the agreement.
The Housing Stock
What Building in Forest Hill Looks Like
Forest Hill homes were largely built between the 1910s and 1940s, with a smaller wave of post-war construction filling in remaining lots. The streets are tightly held, mature trees are protected under Toronto’s urban forestry bylaws, and development is subject to planning controls and, in some cases, heritage oversight by the City of Toronto.
Most projects here fall into three categories: heritage-sensitive renovations of existing homes, full rebuilds where the original structure is no longer viable, or carefully designed additions that integrate into the existing roofline. In all cases, the design has to earn its place, Forest Hill is a neighbourhood where new construction is closely scrutinized.
What We Do
Services We Offer in Forest Hill
Custom Homes
Ground-up custom homes designed for the lot and the street, with full architectural design, structural engineering, and construction handled in-house. Most Forest Hill custom builds run between 4,500 and 9,000 square feet.
Home Additions
Second-storey additions, rear extensions, and garage conversions designed to integrate with the existing home rather than fight it. Particularly common on Forest Hill’s earlier two-storey homes where families want more space without leaving the neighbourhood.
Home Renovations
Full-home renovations, kitchen and bathroom remodels, and structural reconfigurations on existing Forest Hill homes. Heritage detailing, millwork, plaster, original windows, gets preserved or recreated where the project calls for it.
Laneway & Garden Suites
Where zoning permits, a laneway or garden suite adds usable square footage without altering the main home. Forest Hill’s deeper lots make some properties strong candidates.
Design & Permits
In-house architectural design, zoning analysis, Heritage Permit applications where required, and full City of Toronto permit coordination.
Project Management
A dedicated project manager, weekly site meetings, and full Buildertrend access from the day the contract is signed through to handover.

Good To Know
What a Forest Hill Project Involves
A significant number of homes in Forest Hill are listed on the City’s Heritage Register, with some located within Heritage Conservation Districts. Projects involving designated properties require Heritage Permit approval, which can extend timelines but is manageable with the right approach.
Forest Hill’s mature canopy is protected under City of Toronto bylaws. Trees measuring 30 cm or more in diameter require permits for injury or removal, with larger trees subject to increased scrutiny through Urban Forestry. We incorporate arborist assessments and recommendations into the design from the outset.
Forest Hill is primarily governed by Residential Detached zoning, which sets clear limits on height, setbacks, and lot coverage. Many custom homes require minor variances, and we handle the full Toronto Committee of Adjustment application and presentation process as part of our scope.
Forest Hill residents pay attention to what gets built. We design for the street, brief neighbours before demolition, and run sites that don’t make us unwelcome.

Lima Rodwesko, RenovationFrequently Asked Questions
Everything you'd ask before committing.
It depends on your specific property. Forest Hill has both individually listed homes on the City’s Heritage Register and pockets that fall within Heritage Conservation Districts, but plenty of properties carry no heritage status at all. If your home is listed or designated, you’ll need a Heritage Permit before any demolition or significant exterior work, and the review adds three to four months on the front end. We check the Heritage Register as part of our pre-design due diligence so you know exactly what you’re working with before any drawings are commissioned.
Sometimes, but not always. Homes inside Heritage Conservation Districts or with individual designations face significant restrictions on demolition, and the City has actively pushed back on teardowns in parts of Forest Hill. Outside heritage-protected areas, teardown and rebuild is feasible if zoning supports the size of home you want, though Committee of Adjustment is often required for larger builds. We assess feasibility honestly during the consultation rather than leaving you to find out late.
Forest Hill’s canopy is one of the densest in the city, and Toronto protects any tree with a trunk diameter of 30 cm or more, along with all City-owned trees on the boulevard. Before any demolition or excavation, we engage an arborist to assess every tree on and adjacent to the lot, mark out tree protection zones, and submit applications to Urban Forestry where removal or injury is unavoidable. Replacement planting is almost always required when a protected tree comes down. We build these requirements into the schedule from the start so trees aren’t an afterthought that delays the project.
Most Forest Hill custom builds take 20 to 30 months from first consultation to handover. That breaks down into roughly 4 to 8 months for design, drawings, and engineering, 3 to 6 months for permits including any Heritage Permit and Committee of Adjustment work, and 12 to 18 months for demolition and construction. Renovations and additions are shorter, typically 8 to 14 months total. We map out the full schedule before you sign so the timeline is clear from day one.
