The Housing Stock
One Borough, Many Neighbourhoods
North York used to be a separate municipality, and the housing pattern still reflects that history. Most of the residential stock was built between the 1940s and the 1970s, dominated by ranch bungalows, split levels, and postwar two storey homes on generous lots. Renovations and additions adapt these homes to the way families live today.
The current wave of North York work runs in two directions. On lots where the existing home has value beyond the land, families are staying and reworking, most often through second storey additions and full renovations. On lots where the land dominates the value, particularly across Willowdale, Bayview Village, and Ledbury Park, teardown and custom rebuild is the answer. Both paths need the same underlying knowledge of what North York zoning, Committee of Adjustment, and construction conditions actually allow.

Our Process
How a North York Project Runs

- Step 01Showroom visit or call
We walk the site, review the zoning, and discuss what’s feasible, including whether your project is a candidate for renovation, addition, or teardown.
- Step 02Design and Permit
Architectural and interior design developed in house, including structural engineering and any specialized reports required for your site.
- Step 03Scope in writing
The scope is written down before construction begins, including demolition, permits, and any Committee of Adjustment work.
- Step 04Permits
We handle the full permitting process, including any minor variance work and tree protection applications.
- Step 05Construction
Dedicated project manager, weekly meetings, portal access throughout.
- Step 06Completion and Handover
Final walkthroughs, handover, and complete warranty documentation.

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
North York questions, answered
If the answer you need is not here, ask us on the call.
How long does it take to build a custom home in North York?
Most projects take several months for design and approvals, followed by construction that can range from 8 to 14 months depending on complexity and finishes.
Do I need permits to build a house in North York?
Yes. Building permits and additional approvals are required before construction begins. Requirements vary depending on lot conditions and zoning.
Is rebuilding better than renovating?
It depends on the condition of your existing home. If structural upgrades would be extensive, rebuilding can sometimes be more efficient long term.
How much does it cost to build a custom home here?
Costs vary based on size, finishes, and site conditions. A detailed estimate is created after reviewing your plans and property.
What's involved in tearing down and rebuilding on a North York lot?
Teardown rebuild involves demolition permits, environmental screening for pre 1980 homes, asbestos abatement where applicable, utility disconnections, site hoarding, and waste management, before any new build can begin. We coordinate all of it as part of the contract, including temporary utility arrangements if needed. Demolition itself typically takes two to three weeks once permits are in hand. The full teardown and rebuild timeline generally runs 18 to 26 months from first consultation to move in.
Are there heritage rules I should know about in North York?
North York doesn’t have a formally designated Heritage Conservation District, but individual homes across neighbourhoods like Lawrence Park, Wanless Park, Bayview Village, and Ledbury Park carry heritage listings on the City’s Heritage Register. Homes on the Register require a Heritage Permit for significant exterior alterations or demolition, which adds time and design constraints to the front end of a project. We check the Register on every consultation.
