Direct Answer
This page answers the most common questions about building and renovating custom homes in Toronto — including costs ($400–$700+/sq ft for construction), timelines (18–30 months for a custom home), permits, warranties, and what to expect from the Wexler design-build process.
Budget & Costs
Custom home construction in Toronto typically ranges from $500–$700/sq ft at the mid-level, $700–$1,000/sq ft for high-end builds, and $1,000–$1,500+/sq ft for ultra-luxury estates. A 4,000 sq ft custom home in Forest Hill or Rosedale realistically costs $2.8M–$4.5M+ including soft costs, permits, and landscaping. Land is separate. The single biggest cost driver is finish level — the structure is often only 30–35% of total project cost.
Soft costs are everything outside of physical construction: architectural fees (5–10% of construction cost), structural and mechanical engineering, land surveys, permit fees, development charges (which can be $40,000–$100,000+ in Toronto), HST on new builds, lawyer fees, and temporary housing during construction. Budget 15–22% of your construction cost for soft costs.
At the discovery phase, we provide a realistic budget range based on scope and similar projects. At the permit-ready stage, we provide a detailed line-item budget. Our contract price is fixed within the agreed scope — any changes outside that scope are priced as change orders with your written approval. We don't lowball estimates to win work and then recover margin through change orders.
We build a 5–10% contingency into every project budget. On renovations of older homes with unknown conditions behind walls, we recommend 10–15%. Contingency is there for unforeseen site conditions — not for scope changes. If contingency isn't needed, it stays with you.
It depends entirely on the scope. A deep renovation of a 100-year-old home in Forest Hill can cost as much as a new build when you factor in structural upgrades, asbestos/lead remediation, knob-and-tube rewiring, and bringing everything to current code. For many clients, building new on the same lot is more cost-effective and delivers a better result. We'll tell you honestly which makes sense for your situation.
Timelines
Plan on 18–30 months total: 1–2 months for discovery and design development, 4–12 months for full architectural design, 4–16 months for permitting (Toronto's permitting process is notoriously slow), and 8–18 months for construction. Projects with complex heritage overlays, conservation authority approvals, or Committees of Adjustment hearings can take longer. We give you a realistic schedule before you sign anything.
Standard residential building permits in Toronto currently take 4–8 months for straightforward new builds. Complex applications, heritage properties, properties near ravines (TRCA), or projects requiring a Committee of Adjustment hearing can take 12–20 months. We have extensive experience managing Toronto's permitting process — we know what to submit, how to structure applications, and how to minimize unnecessary back-and-forth.
A full gut renovation of a 2,500–4,000 sq ft home typically takes 6–12 months of construction, plus 2–4 months of design and permitting beforehand. Kitchen-only renovations take 8–14 weeks. Heritage restorations vary widely based on scope. We provide a detailed construction schedule before work begins and update it weekly.
The five biggest delay drivers we see: (1) undecided or late finish selections — we need material decisions before we need to install them; (2) slow permit amendments caused by design changes after submission; (3) discovery of hidden conditions in renovation work (knob-and-tube, asbestos, wet basements); (4) long-lead material availability for custom millwork and imported products; (5) scope changes during construction. Front-loading decisions in the design phase is the single most effective thing clients can do to avoid delays.
The Build Process
In a design-build project, the builder is involved from the earliest design stages — rather than receiving architect-drawn plans and bidding on them after the fact. This matters because it eliminates constructability surprises (designs that are beautiful but difficult or expensive to build), front-loads decisions that typically cause construction delays, reduces coordination friction between architect and builder, and usually results in a more accurate budget earlier in the process. We've seen design-bid-build projects arrive on site with budgets 30–40% below what the plans actually cost to build.
Yes. Robby manages client relationships, project oversight, and ensures the vision stays aligned throughout. Mark is personally on-site during every critical phase of construction and reviews every stage. You have their direct contact information from day one. We deliberately limit the number of projects we take on so that every client gets real access to the principals.
A change order is any modification to the agreed scope of work. When something changes — whether client-initiated or discovered on-site — we document it, price it transparently, and require your written approval before proceeding. You will never discover a scope change on your final invoice. Every change is tracked in writing.
Yes. We manage all permit applications, coordinate with inspectors, and handle any required amendments. For projects requiring Committee of Adjustment approval, TRCA permits, or heritage approvals, we work with specialists we've used successfully on past projects.
Working With Wexler
For custom home builds, we work on projects starting at approximately $1.5M in construction value. For renovations, we typically work on projects of $300K and above. We don't have a hard minimum — what matters more is whether the project is a good fit on both sides.
No. You can come to us at any stage — with nothing, with rough ideas, with a site, or with complete architectural drawings. If you don't have an architect, we can recommend Toronto residential architects we've worked with successfully. Starting the conversation early lets us give you better guidance on what's realistic for your site and budget.
Yes. Our primary market is Toronto and the inner GTA — Forest Hill, Rosedale, Lawrence Park, the Bridle Path, Leaside, North York, Etobicoke. We also work in Mississauga, Oakville, Vaughan, Richmond Hill, and other GTA municipalities. Contact us to discuss your specific location.
All new homes are enrolled in Tarion (Ontario's new home warranty program), which provides a 1-year workmanship warranty, 2-year systems warranty, and 7-year major structural warranty. Beyond the legislated minimums, we provide our own fit-and-finish warranty and stand behind our work. If something needs attention after handover, you contact Robby or Mark directly.
Intentionally. We don't advertise aggressively. Most of our projects come through referrals from past clients, architects, and interior designers. We limit our project load so that every client gets real access to the principals. If you found us, someone you trust likely sent you here.
