Renovation & Construction in Willowdale
Willowdale is one of the clearest examples in Toronto of a neighbourhood rebuilding itself one lot at a time. The neighbourhood spreads east and west of Yonge Street around North York Centre, and many of its side streets filled with modest houses during the township-wide building surge that the City dates from the 1950s. Today those deep lots hold a mix of original one-storey homes, enlarged houses and new two-storey custom builds, while condominium towers rise along Yonge Street around North York Centre. For owners, the question is rarely whether to invest but how: renovate, add a storey, or knock down and rebuild. Nexon Build answers that question with zoning, the North York Committee of Adjustment and the City's tree rules mapped out before design begins.
Willowdale, in the heart of North York on either side of Yonge Street, is where post-war bungalows on deep lots are being replaced by custom homes, second storeys and full renovations. As a licensed renovation and construction company, Nexon Build manages feasibility, permits, scheduling, and quality control in Willowdale — every project tracked in Buildertrend so you always know where things stand.

Willowdale History: From Yonge Street Farms to Post-War Streets
Before the suburbs, this stretch of Yonge Street was farmland with small settlements; the City's North York history exhibit names Newtonbrook among the township's early communities that grew up along Yonge Street. Gibson House Museum at 5172 Yonge Street, an 1850s farmhouse, belonged to the family of David Gibson, a surveyor whose first farmhouse was burned after he took part in the 1837 Rebellion, and the City notes that the land around it was once working farmland. The Township of North York itself was created in 1922, and its population surge began in the 1950s, when developers built new housing across the township, including on streets east and west of Yonge.
That timing explains the houses a builder meets today. Many single-family homes on these streets are post-war brick bungalows and storey-and-a-half houses, built with modest basements, small rooms and services sized for another era. Over recent decades, owners have been replacing many of them with large two-storey homes, so a single side street can show every stage of that cycle, from the original bungalow to the enlarged house to the new build, side by side. Along Yonge itself, North York Centre has become a high-rise district, so the neighbourhood holds both condominium towers and long stretches of post-war blocks.
Willowdale Lot Patterns and What They Allow
Willowdale's appeal to builders is depth. Many of its lots run well back from the street, and an original bungalow often covers only a small share of the land. That leaves room for a rear addition, a larger replacement house or, in some cases, a second building in the backyard. What a deep lot does not do is exempt a design from the rules. Toronto's city-wide Zoning By-law 569-2013 sets the limits on height, lot coverage and setbacks that shape every rebuild, and some properties remain subject to a former municipal by-law, so the first step is confirming which by-law actually applies to your parcel.
Two newer permissions widen the options. Since Council's May 2023 decision, Toronto has permitted multiplexes of up to four units city-wide, so a Willowdale rebuild can be designed with a rental or family unit from the start. City Council approved garden suites in February 2022 for residential zones under By-law 569-2013, with one suite per lot and a building permit required; the permission does not extend to lots still under the former North York by-law. On these lots, protected trees and separation distances usually decide whether a garden suite fits, which is why we test the house, any suite and the trees together at feasibility. Our multiplex rules guide explains the unit permissions in more detail.
Permits, the North York Committee of Adjustment and Willowdale's Trees
Building permits for Willowdale are handled by Toronto Building's North York district, based on the first floor of the North York Civic Centre at 5100 Yonge Street. Plans are checked against the zoning by-law during permit review. Where a design exceeds a limit, the owner applies for a minor variance to the Committee of Adjustment, which sits in four panels matching the City's Community Council areas; the North York panel draws on ten members appointed from North York. Its decisions can be appealed to the Toronto Local Appeal Body. We typically add three to four months to the schedule when a hearing is needed, and our Committee of Adjustment guide explains the process.
Mature trees are the second early constraint. Under Toronto's Private Tree By-law, trees on private property with a diameter of 30 cm or more cannot be injured or removed without a permit, and a building permit does not authorize that work. Willowdale's older lots often carry large trees close to where an addition or new foundation would go, so an arborist's assessment shapes the footprint. Where a property touches a valley or watercourse within the Toronto and Region Conservation Authority's regulated area, a TRCA permit or clearance is needed before the City issues a building permit, and tree work goes to the City's ravine protection staff as well.
Knockdown Rebuilds and Custom Homes in Willowdale
A Willowdale knockdown rebuild moves through predictable phases. Feasibility covers the survey, zoning analysis and tree review. Design and permits typically take two to six months, longer with a variance, and include a separate demolition permit for the existing house. Construction then runs five to fourteen months depending on size, finishes and site conditions. Every ground-up custom home Nexon builds is enrolled in Ontario's Tarion new home warranty, which matters to buyers if you ever sell. Our Willowdale custom homes page covers the rebuild process here step by step.
On site, the builder's work starts before demolition. Neighbouring houses sit close to the side lot lines, so excavation, shoring and hoarding are planned to protect them, and tree protection fencing goes up before machines arrive. A new two-storey house also needs services sized for it rather than inherited from a bungalow: a larger water service where required, new drains, and heating, cooling and ventilation designed for the full floor area. We schedule City inspections at the footing, framing, mechanical rough-in, insulation and occupancy stages, so problems surface while they are still cheap to fix.
Second Storeys and Full Renovations of Willowdale Bungalows
Not every owner wants to rebuild. A second-storey addition keeps the existing footprint, the backyard and often the mature trees, while roughly doubling the living space above grade. The structural question comes first: whether the original footings and walls can carry another floor, or whether they need reinforcing or underpinning. A structural engineer answers that before design is fixed. A second-storey addition in Toronto usually lands around $300K to $550K all-in, and a rear extension can be combined with it. Details are on our Willowdale home additions page.
When the house is sound and the size is right, a full renovation can be the better value. Gutting a post-war bungalow usually means new wiring and a new panel, new supply and drain plumbing, insulation and air sealing, and a reworked layout, often with an engineered beam replacing a central bearing wall. Low basements are common too, and underpinning to gain usable height is often a $35K to $85K line item on its own. Our Willowdale full renovations page explains how we scope and phase that work.
What Willowdale Projects Cost in 2026
Construction cost for a ground-up custom home in Toronto typically runs $350 to $650 per square foot in 2026. For a 4,000 sq ft Willowdale house, that means roughly $1.4M to $2.6M to build, before land, design, engineering, permit fees and other soft costs. Where a project lands in that range depends on finish level, structural complexity and site conditions. Demolition, tree protection and any shoring for close neighbours are site costs that belong in the budget from the first estimate, not discoveries made after the old house is gone.
Additions cost more per square foot than new construction, typically $400 to $700, because the work ties into an existing structure, roof and mechanical system. Full home renovations range from about $150K for a mid-level refresh to $450K or more for a full gut with standard finishes, and $800K or more at a premium level, or roughly $200 to $450 per square foot for a full gut. When renovation and addition costs approach the price of a new house, rebuilding often makes more sense; our guide to renovating versus rebuilding sets out how to compare them.
How Nexon Runs a Willowdale Project, and Nearby Areas
Nexon Build is led by three founding partners with more than 70 years of combined experience. Kash Varjavandi, our master builder, manages timelines, coordinates trades and keeps clients informed. David Bocharov brings civil construction experience that includes high-rise and multi-unit residential work, and Fred Shik makes sure heating, plumbing and mechanical systems are designed and installed correctly. Projects run under fixed-price contracts with one accountable team, and every schedule, photo, selection and change order sits in the Buildertrend client portal. You can review our completed work in Toronto and York Region on the projects page.
Willowdale sits at the centre of North York, and our North York area page covers neighbouring districts such as Bayview Village and Hoggs Hollow. Further north, beyond Steeles Avenue, Thornhill raises many of the same rebuild and addition questions under different municipalities. Wherever the lot is, we start with a site visit, a zoning and tree review, and a budget conversation grounded in real 2026 costs. Call (647) 829-0272 or request a free online estimate to begin.
Common questions — Willowdale
Can I tear down a Willowdale bungalow and build a two-storey house without a minor variance?+
Yes, if the new house fits Zoning By-law 569-2013, or any former by-law that still applies to the lot. Many owners choose a larger design that needs relief on height, coverage or setbacks, which means a hearing before the North York panel of the Committee of Adjustment. We test both options at feasibility so you can weigh size against time.
Does the Yonge Street condo corridor change what I can build on a Willowdale side street?+
Not directly. The towers are concentrated on and near Yonge Street around North York Centre, while the residential side streets generally carry low-rise zoning for houses. Since 2023, Toronto's low-rise residential zones have permitted up to four units, so a side-street rebuild can include a rental suite, but tower-scale density does not extend onto the bungalow blocks.
Do I need a City permit to remove trees for a Willowdale rebuild?+
For any private tree with a diameter of 30 cm or more, yes. Toronto's Private Tree By-law requires a permit to injure or remove those trees, and a building permit does not cover that work. Trees in ravine-protected areas are reviewed by the City's ravine protection staff, so an arborist report is usually part of our first design package.
Can a new Willowdale home include a basement apartment or garden suite?+
Often, yes. Toronto permits up to four units in detached houses city-wide, and garden suites have been allowed since 2022 on lots zoned under By-law 569-2013, though not on lots still under the former North York by-law. Each unit adds fire separation, exit and servicing requirements, and a garden suite has its own height, setback and separation rules, so we design the main house and any suites together rather than adding them later.
How long does a Willowdale knockdown rebuild take from first meeting to move-in?+
Plan on roughly 12 to 18 months for a typical project. Design and permits take two to six months, a Committee of Adjustment hearing can add three to four, and construction runs five to fourteen months depending on size and finishes. Locking decisions early and ordering long-lead materials as soon as permits are issued keeps the schedule tight.
Does Nexon Build serve Willowdale?+

Do you handle building permits in Willowdale?+
Yes. We manage the full permit process with City of Toronto (Toronto Building North York district & North York panel of the Committee of Adjustment), including any Committee of Adjustment or minor-variance review your Willowdale project requires.
How much does a renovation cost in Willowdale?+
Renovation costs in Willowdale track the wider GTA market: kitchens from about $30K, bathrooms from about $15K, full home renovations $150K–$800K+, and ground-up custom homes at $350–$650 per square foot. Your number depends on scope, finish level, and the condition of the existing home.
What kinds of homes do you renovate in Willowdale?+
