What you are starting from.
A 1930s Leaside bungalow, an Edwardian semi in Bloor West and a 1960s Willowdale side split each have distinct construction details. Experience with these homes helps us plan the structural and renovation work.

The Neighbourhood Decides What You Can Build
Toronto is not one place to build in. The housing stock, the lot, and the approval route change street by street, and all three are settled before a price means anything. These are the neighbourhoods we know best.

The neighbourhoods
Where we work, and what changes between them.
Bayview Village
Midcentury homes on mature lots, replaced by architecturally serious new builds.
The Beaches
Victorian semis, Arts and Crafts detached homes, and frame cottages built for summer.
Bloor West Village
Edwardian homes on narrow, deep lots, with opportunities to create more living space.
Cliffcrest
Ravine lots on the Bluffs, where TRCA setbacks and slope stability decide the design.
Danforth
Century brick semis taking rear and third storey additions, and laneway suites behind them.
Forest Hill
Georgian and Tudor estates, mature streets, and heritage sensitive design.
Leaside
1930s brick bungalows turned into homes that hold a family for thirty years.
Ledbury Park
Wide lots and mature trees between Avenue and Bathurst, being rebuilt with care.
North York
Teardowns, rebuilds and renovations across an area with a different rule in every pocket.
Rosedale
Heritage Conservation Districts, century masonry, and ravine approvals.
Willowdale
The busiest teardown and rebuild streets in the city, on wide lots near the Yonge line.
Why The Address Matters
Three things change between one street and the next.
Before we price a project, we review three local factors: the existing home, the lot, and the approval route. This gives us a clear basis for the scope and price.
What the lot will carry.
Frontage, depth, coverage, the height envelope, and whether a rear addition eats the setback. Two houses that look alike from the street can have entirely different room to grow.
Which approval route you end up on.
As of right, Committee of Adjustment, or a heritage permit on top. That choice is worth months, and it is decided by the lot and the district, not by how the drawing looks.
The Approval Route
Three ways a Toronto project gets permission.
The approval route affects when construction can begin. Review the zoning, heritage status and application requirements for the address before setting a start date.
The design stays inside the zoning bylaw, so no hearing is needed and the application goes straight to a building permit. The fastest route, and the one we design toward wherever the lot allows it.
Where the design needs more than the bylaw allows, a minor variance application may be needed. Confirm the submission requirements and hearing process for the property. Approval and timing remain subject to the reviewing authority.
In a Heritage Conservation District, and on individually listed properties, the elevation, materials and window pattern are reviewed as well as the size. It is workable and we work in it regularly. We review these requirements before preparing the drawings.
What We Build Here

The neighbourhood decides the constraints. It does not change the contract, the team, or the way the price is set.

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.
Grand Design Build did a great job on our renovation. Their team was organized, kept us informed through each step, and also delivered quality work. They were reliable with timelines and very clear about costs and materials. Overall, we had a very smooth experience with them. Highly recommended!

Frequently asked questions
Questions homeowners ask before they call
If the answer you need is not here, ask us on the call.
My neighbourhood is not on the list. Do you build there?
Probably. A neighbourhood gets its own page here once we work in it often enough to have something specific to say about it. The list of areas we serve is longer than the list of pages. Send us the address and we will confirm whether we can staff and supervise your project.
Does the address change the price?
Not as a travel surcharge. It changes the price through the work itself: a ravine lot with TRCA setbacks, a heritage district that decides your window pattern, or a narrow street with no room for a bin all cost real money. Those costs are shown in the scope before work begins.
Do you know my street's Committee of Adjustment history?
For the neighbourhoods on this page, usually yes, and it matters more than people expect. What has been approved and refused nearby is the best available evidence for what your application will meet. Where we do not know a street, we look it up before we advise you, not after.
My house is in a Heritage Conservation District. Is that a no?
No, and it is more common than people think in Rosedale, Forest Hill and parts of the Beaches. It adds a review of how the house looks from the street, and it constrains materials and window patterns. It can limit the proposed work. Feasibility and approval need to be assessed for the specific property.
Do you take on more than one project in the same neighbourhood at a time?
Sometimes, and it is usually an advantage for both: the same trades, the same inspector, and a crew that already knows the local conditions. Each project keeps its dedicated coordinator when we take on nearby work.
We are outside Toronto proper. Same process?
The process is the same and the rulebook is not. Every municipality has its own zoning bylaw, its own committee, and its own permit timelines. We will tell you what is different about yours before you commit to anything.
