If you are looking for a custom home builder in North York, the first number to know: a custom home here typically costs $500 – $1,500+ per square foot to build in 2026, before land, depending on size, design and finishes. Most North York custom homes replace a 1950s–60s bungalow or split-level on a wide lot, especially in Willowdale, Hoggs Hollow and Bayview Village, where many original houses have already been replaced by larger new homes. We deliver custom homes with our licensed builder partner, and handle design coordination, project management and the trades.

Custom Home Builder in North York: Key Takeaways
- Cost: $500 – $1,500+ per sq ft of construction, plus design, permits, demolition and site servicing.
- Zoning: new houses on older North York lots often need a Committee of Adjustment variance for height, floor area or setbacks.
- Ravines and trees: lots in Hoggs Hollow, Bayview Village and along the Don valleys can need ravine, TRCA and tree permits, which shape the footprint.
- Timeline: about 20 – 36 months from first design meeting to move-in.

Where North York Custom Homes Are Built
Willowdale
Willowdale has many post-war bungalows on deep lots, and many of them have already been replaced by new custom homes. Here the zoning limits on height, length and floor area drive the design, and most projects go to the Committee of Adjustment.
Hoggs Hollow and York Mills
Hoggs Hollow was built in stages from the 1920s to the 1960s, and many of its original estate and modernist homes have been replaced by large new houses. Lots here are in or near the York Mills valley, so ravine permits, TRCA approval, slope studies and tree protection are part of almost every project, and they set what can be built where.
Bayview Village
Planned in 1954 with curving streets along the East Don valley, Bayview Village has many ravine lots with 1950s–60s bungalows and split-levels. Replacement homes here are designed around the ravine setback and the existing trees, which often favours building up rather than out.
Don Mills
Don Mills' modernist houses from 1953 to the mid-1960s are increasingly valued as they are, so whole-home renovations and sympathetic additions are often a better fit than a rebuild.
The Rules for Building New in North York
- Demolition and building permits: issued by Toronto Building. Under the Ontario Building Code, the City must decide on a complete house application within 10 business days, but most new-home timelines are driven by design and variances, not that clock.
- Zoning and variances: Zoning By-law 569-2013 (or a former by-law on some lots) sets height, floor area, coverage and setbacks; going beyond needs a Committee of Adjustment hearing with notice to neighbours.
- Trees and ravines: private trees 30 cm or wider need a permit to injure or remove, and in ravine-protected areas all trees are protected; ravine permits and TRCA approval come first on valley lots.
How a North York Custom Home Runs
- Feasibility (4 – 8 weeks). Survey, zoning review, tree and ravine check, and a budget range.
- Design (3 – 6 months). Architect, structural and mechanical design, and interior selections.
- Approvals (3 – 9 months). Committee of Adjustment if needed, tree and ravine permits, then demolition and building permits.
- Construction (12 – 18 months). Demolition, foundation, framing, envelope, mechanical, finishes.
- Completion. Final inspections, occupancy and a final walkthrough with you before move-in.
