Home Addition Cost: Toronto vs. Montreal

A home addition project is not to be taken lightly and may be the best decision you make for your home. There are several factors to consider when contemplating where an addition is the right option for you and there are several different ways in which an expansion can be implemented.

Whether for aesthetic reasons, a lack of space, a need for change or simply because you want your home to grow in value, there is certainly a type of addition that will suit the needs of you and your family. 

So, how much does a home addition cost?

Home Addition average costs (materials and labour):

  Economy Standard
On Piers – Turnkey $140 / sq ft $175 / sq ft
On Piers – Unfinished $110 / sq ft $125 / sq ft
On Foundation/Slab – Turnkey $170 / sq ft $215 / sq ft
On Foundation/Unfinished $125 / sq ft $170 / sq ft
4 Seasons Solarium $145 / sq ft $185 / sq ft

Would you like to know the cost of your home addition?

Consider your investment

Adding a room to your ground floor can significantly change the pace of your home and dramatically increase its value. Although the price of a home addition is steeper in Toronto than in Montreal, the return on investment can also be greater in Toronto. According to a news report in the Financial Post, Toronto home prices are projected to increase by 20-25% in 2017.

This figure also shows how difficult it is to buy a new home in Toronto and other communities of the Greater Toronto Area. You may get a good price for your current home but buying a bigger home that can accommodate your family member’s needs can become an uphill task for you.

So, don’t settle for giving up your current home, especially if you’re fond of the location. Instead, increase its size and customize it to suit your needs. Think of all the possibilities with a home addition project and make space in your home without leaving it. You can consider a bump-out addition to avoid making changes to the roof as well as the foundation or if you don’t want to part ways with the beautiful landscape of your home and need more space, think of a second-floor home addition. It will help you to create several rooms in your home and ensure that your need for space is met adequately.

Save with a home addition built on piers

It’s often advisable to carry out a lateral extension on a solid foundation, but you can be certain that this type of work is much more expensive and complex. There are, however, other options you can consider such as a room addition which is built on piers injected into the earth. Choosing this option will save you money and has many benefits. Indeed,  a house on piers is very resistant to unstable soil and can, therefore, be constructed more easily. In addition, the machinery required and extent of the work is significantly less than what is involved when the construction of a foundation is required.

It should be also be noted, however, that this type of home expansion may cause your interior to be more resilient to heating for the simple reason that the base of your extension will be more exposed to the elements.

In terms of cost, you potentially maximize your return on investment. The cost of a pier house extension averages approximately $110 to $175 per square foot depending on whether you would like a fully finished turnkey solution or unfinished.

Or with an addition built on a concrete slab instead of a foundation

A second option would be to extend your house laterally and lay it on concrete slabs, an excellent solution to avoid digging a new foundation while at the same time staying warm during the winter. Your expansion will be based on a monolithic concrete slab that serves both as a foundation and as a floor. The insulation of this type of flooring is not very complicated and you will have no problem keeping in the heat during the winter. If you choose this expansion option, you must first verify that your land can support this type of structure. Concerning the price of a house expansion on a concrete slab, it is generally estimated to range between $165 to $195 per square foot.

When looking for a detailed cost estimate for a home addition project, you have to take into consideration several factors such as labour, materials and fixtures. You will also need to consider the cost of hiring an architect as well as a structural engineer.

Per-square-foot cost of a home addition project

On average, the total cost of a home addition project can range anywhere between $21,000 to $150,000 but the actual cost of your project will depend entirely on your specific requirements. Are you planning to add a small room to your Toronto home or interested in a complete second-story addition? Usually, home addition costs vary from $80 to $200 per square foot.

A detailed budgetary estimate to help you make a decision

The price varies from one project to another. However, it will include the following things:

  • Architect fees which can make up 10-18% of the total project cost.
  • Excavation and demolition fees are also a factor you should take into account. Usually removing a wall costs at least $300.
  • Basic framing expenses which include the expenditure of building walls can cost something in the range of $6 to $8 per square foot. So, if you are interested in a room addition of 1,000 square feet, the framing cost will be approximately $8,000.
  • Drywall costs for 1,000 square feet can be close to $2,000 and with insulation costs coming in at approximately $1,200.
  • Roofing costs of the new addition will vary according to your choice. Metal roofing is a pricier option, for example. On average, you can purchase roofing material from $5 to $50 per square foot, so there is quite a broad range of options to consider but you may be restricted depending on your type of roof structure.
  • Licensed electricians tend to charge $50-$100 per hour on average for wiring the room addition.
  • If you are looking for a fully-functional bathroom addition or kitchen addition, you will have to consider the additional plumbing costs as well.
  • You’ll also need to keep money aside for electrical fixtures, furniture, accessories and appliances required to complete the new living space.

Choosing a reputable and experienced home addition contractor is key!

Undertaking a home addition project on your property involves spending time and money and you certainly don’t want an inexperienced contractor handling the work. If you choose a home addition contractor on the basis of cost alone, you may be making a big mistake. You may have to spend more money rectifying errors and the heartache that can cause will be phenomenal.

So, make a smart hiring decision and choose a reputable contractor with adequate experience in home additions and extensions. Research their past projects and talk to their past customers to get a clear idea of the quality of their work. It will give you much greater peace of mind and increase the likelihood of a stress-free home addition.

How to add a living space without a home addition

When looking to add a room to their house, most people will first think of building a home addition.This is a great way to expand your home’s living and storage space, however, it can come with some major drawbacks.

Firstly, building a home addition can cost a lot in permit fees and it can cause your property taxes to increase which will eat into your return on investment. Yes, additions are likely to raise your home’s value, but, if they cause a too significant rise in these costs, the increase in value can potentially become meaningless.

Secondly, they are expensive on a square-foot-basis. Adding a room is one of the most expensive home improvements you can make.

Is there a way to increase living and storage space while avoiding unnecessary costs?

The good news is that yes, you can increase your home’s resale value, living and storage space easily and without the problems associated with a typical home addition.

How? With a crawl space to basement conversion or, if you already have a full basement, you can finish it and dramatically increase your living space.

If you have a crawl space, you’ll be happy to learn that it is often possible to convert it into a full-sized basement. It is almost impossible to do on your own. The job is extremely labour intensive and needs special equipment to perform. So, it’s crucial to find a local contractor with the expertise necessary to dig out your crawl space and turn it into a full basement successfully.

If you already have a basement, finishing it is the way to go. A simply drying-out and waterproofing can ensure the room is no longer exposed to the elements and fully finishing it effectively e.g. framing and upgrading the floors and walls, can ensure your basement is successfully transformed into your new dream living area.

If your basement is one large open space, adding rooms can give you a whole new functional, livable floor in your home. This would also be much, much cheaper on a per-square-foot basis than a home addition and will also take less time.

If you have an idea as to what type of addition you would like to undergo or would simply like some more information, give Reno-Assistance a call on 1-888 670 9742 or fill out our contact form and an advisor will be in touch to help you with your project and refer the best local house extension specialists that have met our stringent 360° verification criteria.
