There are different ways to add square footage to your home. Here are the most common ways to do it and a rough idea of the cost of each one. Please note that the prices mentioned below are approximate and vary according to the dimensions of the extension, the constraints encountered in carrying it out, the materials chosen and the location of the house.
Addition of a complete floor
Do you need several additional parts? Adding a full floor may be an interesting solution for you, provided your home meets the following conditions: the municipal by-law allows the addition of a second floor to your residence and a qualified structural engineer has confirmed that the floor and the frame of your house are capable of receiving it. If, in addition, it is not more profitable to shave everything and start from scratch and you want to live in your house for several more years, this type of extension is ideal! Approximate minimum cost: 110 000$
Addition of a garage annexed to the house
A garage attached to the house combines several advantages. If that of being able to transit between the car and the house sheltered from the cold and bad weather is the greatest, its price – more affordable than that of a detached garage – is not to be neglected. However, great attention must be paid to insulation and sealing in order to maintain good air quality inside the house. Approximate minimum cost: 50 000$
Cantilever extension
This type of extension consists of enlarging a room located on the first floor of the house towards the outside. Thus, the added part is left without direct support, hence the term “cantilevered”. This technique is ideal when you only want to enlarge a room by a few square feet. Approximate minimum cost: 25 000$
Addition of a floor on an existing garage annexed to the house
According to Richard Lahaye, president of the Order of Chartered Appraisers of Quebec, this would be the simplest and most economical way to expand a home. You can even reuse the roof truss, and since the garage rests on a concrete slab with good load-bearing capacity, you don't even have to touch the foundation," he says, noting that you have to ensure that the walls can support an additional floor. Approximate minimum cost: 50 000$
Addition of a room on the ground floor
Extending the house to the rear to accommodate a canopy, living room or dining room is very common. “The simplest and most profitable way to enlarge a property at ground level is to opt for construction on piles that descend below the frost level,” advises Mr. Lahaye. Because it does not require excavation, this quick and economical method is also the one that damages the land the least. A detail not to be overlooked! Coût minimum approximatif: 60 000$
