From Initial Assessment To Final Walkthrough

Custom Home Construction in Mississauga and The GTA

Since 1995, GrandBuild Homes brings design, engineering, construction, and finishing together under one contract, giving you one clear path from property to finished home.

We Assess Your Property Before Construction

The first step is to understand the property to assess whether it's right for custom home construction. Our company goes through these steps before the construction begins:

Property Assessment: We review the lot, what can be built, and the requirements that will shape the project.
Finding the Right Lot: If you do not own land, we can help you find a suitable property and assess its potential.
Infill & Tear-Down Rebuilds: We work on infill properties and replace existing bungalows or older homes with new residences.
Typical Home Size: Most of our projects range from 3,000 to 5,500 square feet.

Our Design-Build Process Under One Team and One Contract

Building a custom home involves many decisions, from initial design and engineering to permits, construction, and final finishes. We bring these stages together through one home design and build service under a single contract.

This keeps communication clear and limits unnecessary handoffs between different companies. Each stage stays connected, with our team coordinating the work from the first plans through the finished home.

Your Home's Blueprint: Planning Before Construction Begins

Before construction starts, our company works through the details that determine what can be built and how the project will proceed.

We develop the working drawings around your property, zoning requirements, project scope, and the way you want the finished home to function. Our team also coordinates the engineering and approvals needed for construction.

This can include zoning, committee of adjustment requirements where needed, and building permits. Once the plans, approvals, and scope are in place, we establish the construction schedule and move the project forward.

Our 6 Steps Custom Home Construction From Design To Completion

From the initial drawings and approvals to the final walkthrough, we manage the whole construction process under one contract.

Architecture and Design

We develop the working drawings around your lot, zoning requirements, project scope, and the way you want the finished home to function.

Permits and Approvals

We coordinate zoning, engineering, committee of adjustment requirements where needed, and building permits. Our team handles the municipal process before construction begins.

Demolition and Site Preparation

For a tear-down rebuild, we coordinate demolition and prepare the property for construction. This includes excavation, foundations, and required utility connections.

Structure and Building Envelope

We manage framing, roofing, windows, exterior cladding, insulation, and waterproofing. These components form the structure and exterior envelope of the home.

Mechanical and Interior Construction

We coordinate HVAC, plumbing, electrical, insulation, drywall, millwork, tile, and flooring as the home progresses through construction.

Finishes and Final Handover

The final stage includes kitchens, bathrooms, stairs, lighting, and other finish details. We complete the final walkthrough, close outstanding deficiencies, and prepare the home for handover.

What Does a Custom Home Cost?

Every custom home is different, so we start with ranges to give you a realistic idea of cost before your project is fully planned out:

These figures cover construction only. Land is separate.

Your final custom home construction cost depends on the property, size, design, materials, finishes, and construction requirements. After we walk the property and establish the scope, we provide an itemized price before breaking ground.

That price is fixed unless you decide to change the project.

How Long Does It Take to Build a Custom Home?

Most GrandBuild projects take 12 to 18 months from the first drawing to move-in.

The size of the home and project scope affect the schedule. Municipal approvals can also affect when construction begins. Zoning requirements, committee of adjustment hearings, and permit processing are common factors.

We establish a realistic schedule at the start instead of promising a timeline that the project may not be able to meet.

A Company With 30 Years of Custom Home Building Experience

We bring over three decades of custom home building experience, backed by credentials that set the standard for accountability.
