Planning Your Project

Custom Build Budget

Custom builds involve many variables — lot conditions, design complexity, material selections, and mechanical systems all influence the final cost. We provide a detailed, phased estimate and work with you to make informed trade-offs that keep your project aligned with your budget.

Construction Timeline

A typical custom home build takes several months from groundbreaking to move-in, depending on size and complexity. We create a detailed construction schedule at the outset and provide regular milestone updates so you always know where things stand.

Getting Started

The journey begins with a free consultation where we discuss your vision, review your lot or existing property, and outline the steps ahead. We will prepare a comprehensive proposal that covers design, permitting, construction, and timeline.

Frequently Asked Questions

How long does it take to build a custom home?+
Build timelines vary based on the size and complexity of the project, as well as permitting and weather factors. Most custom homes take several months from foundation to completion. We provide a detailed schedule during the planning phase so you know what to expect.
Do I need to already own a lot to get started?+
Not necessarily. We can begin the design and planning process while you are still searching for the right property. Having a lot selected allows us to factor in site-specific conditions, but early planning conversations are always valuable.
How much input do I have in the design?+
As much as you want. This is your home, and we build it to your specifications. Whether you arrive with a complete set of architectural drawings or just a collection of ideas, we work with you at every stage to ensure the final design reflects your vision.
What warranty coverage applies to a new custom build?+
Your build is covered by our workmanship warranty, and we are fully WSIB insured. Where applicable, Tarion Warranty coverage provides additional protection on new home construction in Ontario, covering major structural elements and more.
How do you handle cost changes during construction?+
We provide a detailed estimate upfront and work hard to stay within budget. If changes arise — whether from your design preferences or unforeseen site conditions — we discuss them with you immediately, provide updated pricing, and only proceed with your written approval.
