Though the above information should only serve as a very rough guide, you can see that the majority of the costs to build a house in Ontario are allocated to components that are unavoidable when building any type of house. However, there are some variables that affect costs more than others. For example, installing a metal roof can cost almost 3 times the cost that traditional asphalt shingles would. Additionally, implementing smart technologies in HVAC and electrical systems and opting for insulation upgrades to increase R-factors and energy efficiency can be costly, and fixture upgrades can double or triple the average cost of interior doors or lighting depending on the materials used.

Soft Costs For A New Custom Home Build

A home is more than just bricks and mortar. There are many steps before the shovel goes into the ground. Before construction begins, you will be expected to conduct a survey, do a zoning review, and provide an environmental report to ensure that the location of your home is up to local building standards.
All these steps are called soft costs and should be included in your budget when you are planning your new home.
The next step in pre-construction is putting together design plans and renderings that will help you visualize the completed home. This will require the consultation of architectural designers who will develop a rendering of the exterior of your home. Next, interior designers will bring together the details and finishes you want with an interior design rendering.
This is a fun and exciting part of bringing your vision to life allowing you to make changes and adjustments to improve the functionality of your home with the click of a mouse.


Once you have decided on a plan, structural and mechanical engineers work out the construction elements to ensure your home meets all guidelines and building codes. They also ensure that all the technical specifications are in line.
Finally, it’s time to decide on landscaping, which will require an arborist report. This will outline the right trees and landscape based on your climate and will ensure no invasive species are being used in your design.
The total of your soft costs should run between $30,000 and $50,000.
Custom Home Construction Hard Costs
Costs associated with the physical construction of your home are the hard costs. These include any demolition and excavation at the start of your project.
Now it’s time to get building. The cost of custom home construction varies based on the size and style of the home you choose to build. Based on the average home size of 3,000 square feet, you can expect to pay:


- $220 per square feet for a low end or modest home.
- $250 per square for a classic two-story home.
- $275 per square foot for a modern/more upscale home.
- $300 for a luxury custom home build outside the City of Toronto (Vaughan, Markham, Richmond Hill area).
If you are looking to build a log or timber frame home such as a cottage or guest house, you can expect to pay $270 per square foot.
Other Custom Home Expenses
When budgeting for your new home, it’s important to remember all the interior design elements like appliances and bathroom fixtures. Most homeowners can expect to pay $18,000 to $50,000 depending on the level of luxury they want to add to their project.
Nick’s Developments can help you find the right appliances and fixtures for your home that fit into the design and style you want to achieve without going over your budget.


Always remember to factor in any building and permit fees that may be required by your municipality. Homeowners may also be expected to pay:
- Land Transfer Tax
- Disconnection and reconnection fees for hydro, water, and sewer
- Landscaping fees to remove any trees that may interfere with construction or safety
- Final inspection fees
- Real Estate and Legal Fees
How to Save on Building a Custom Home
Building a custom home in Toronto can be quite the expensive undertaking. There are ways however to save on the investment. For starters, consider your location. Choosing to build in the busy city as opposed to a much quieter, rural area will cost more. Secondly, consider your materials.
A prefabricated, also known as “prefab” or “modular” home are often less costly by a significant margin than a “stock-build” home because they are easier and faster for contractors to build.


Next, consider the size of the home you are looking to build. Ask yourself: Do I really need a 3,000 sq. ft. home, or can I live more minimally? Do I want a finished basement? How many bedrooms and bathrooms do I need? Another way to save money is to not do everything at once.
Even if you do want a basement, you can always save the renovation for later in the future when you’ve had a chance to rebuild your finances. Lastly, always remember to not skimp out on labour. Find the best professionals you can, they are building your home after all!
Remember, cost of goods are always changing and as such, you should allow for an increase or decrease in the cost of your project of approximately 10 percent.
Nick’s Developments are committed to keeping our clients informed about any changes or adjustments to their custom home build project so there are never any surprises.
