What we build in Forest Hill

Services We Offer in Forest Hill

Custom home construction, renovations and additions in Forest Hill, thoughtfully planned before construction begins.

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 postwar 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 considers the established character of Forest Hill and its streetscape.

Good To Know

What a Forest Hill Project Involves

Check the property's current heritage status and the proposed work before design advances. Listed and designated properties have different requirements. Confirm any heritage submission with the City.
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 manage sites with consideration for the neighbourhood.

  • 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.

  • 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

Forest Hill questions, answered

If the answer you need is not here, ask us on the call.

Are heritage rules going to limit what I can build in Forest Hill?

Start with the current Heritage Register and district boundaries. Listed and designated status are different, and the required review depends on the property and proposed work. Confirm demolition or alteration requirements with the City's heritage team before proceeding.

Can I tear down and rebuild in Forest Hill?

A Forest Hill teardown and rebuild requires a property review. Check heritage status, zoning, trees, existing structures and the proposed replacement home before deciding. Any demolition permission, building permit or minor variance must be resolved through the relevant authority.

How does the City’s tree bylaw affect Forest Hill projects?

Protected trees can affect demolition, excavation and the proposed footprint. Identify relevant trees and confirm the arborist's recommendations and City permit requirements before construction. Tree protection and any approved replacement planting belong in the project scope.

How long will a Forest Hill project take from start to finish?

A Forest Hill custom home, renovation or addition needs a schedule based on the property and scope. Design, engineering, heritage review, any variance application and construction each affect timing. Confirm the proposed sequence and its assumptions before making moving arrangements.
