How Long Does a Custom Home Take to Build?
It’s one of the most common questions for anyone considering a custom home build—how long does it take to build a custom home?
Building a home from the ground up is a major life investment, and knowing what kind of timeline to expect is key to making informed decisions, managing your schedule, and setting realistic expectations.
As of April 2025, Ontario has seen a strong upswing in new housing starts, rising by 25.8k units to 64.1k, according to TD Economics. This uptick reflects increasing demand and activity, but also means municipalities and builders alike are juggling a heavier load, potentially affecting timelines.
Let’s walk through all of the various factors that affect the design and construction process involved in creating a bespoke home.
The Planning Phase: Where the Timeline Really Starts
The clock doesn’t really start when construction begins. The early stage—designing your home, working through the permitting process, securing financing, and finalizing specifications—can take several weeks to several months, depending on the complexity of the project.
Design complexity, zoning constraints, and neighborhood guidelines all play a role here. A good builder will help guide you through all the details and ensure you have a clear roadmap before breaking ground.
Obtaining Necessary Permits
One of the biggest variables in any house build is the permitting process. Obtaining permits can take weeks or even months, depending on your municipality’s backlog, your lot’s characteristics, and whether variances are needed. This is especially true in teardown or infill situations, where site preparation and foundation work must adhere to tight regulations.
This step is where experienced builders make a difference. At Montbeck, we handle this phase directly, removing guesswork and reducing the risk of construction delays.
The Construction Phase: Average Timeframes
Once permits are secured and site prep is complete, the construction phase begins. While there’s variation, most high-end custom homes in the Greater Toronto Area take anywhere from 10 to 16 months to complete after breaking ground. Here’s a simplified breakdown:
Site Preparation & Foundation Work: 1–2 months
Framing & Exterior Structure: 2–3 months
Mechanical Systems & Interior Walls: 2–3 months
Interior Finishes & Unique Features: 3–5 months
Landscaping & Finishing Touches: 1–2 months
How fast can you build a custom home? Technically, a basic structure could go up in as little as 6–8 months under ideal conditions, but for a fully customized residence with premium features, the construction duration is typically longer.
What Makes the Timeline Stretch?
Several factors can extend your project’s timeline:
Weather conditions: Heavy snow, rain, or heat can halt or slow work
Custom selections: Bespoke materials or rare finishes may have long lead times
Changes mid-build: Deviating from the original plan and adjusting layouts, finishes, or systems can add weeks
Trade coordination: Delays in one trade can ripple through the entire schedule
The hardest stage in building a house? Many homeowners would say it’s decision fatigue—choosing every fixture, finish, and feature without getting overwhelmed. That’s why we structure the process to simplify choices without sacrificing customization.
Budgeting for Time and Cost
Timeline and budget go hand-in-hand. Uncertainty around total costs often stems from fragmented quotes and vague allowances. At Montbeck, we mitigate this by providing detailed estimates early and managing the total project from start to finish. This clarity gives you control—and peace of mind.
We also offer a financing option that’s tailored for new home builds, which can help balance timing and cash flow.
