What is a home expansion?

Residential house expansion to increase space.

A home expansion essentially consists of increasing the living area of ​​a house either by:

The main reason for selling a house in Quebec is the lack of space when people start a family.

However, the option of expanding one’s property is very real. It is possible to speak with a specialist, free of charge and without obligation, to assess whether this is ideal for your needs and your property.

Home Addition VS Floor Addition – What’s the Difference?

What is the difference between expanding a house and a floor addition project?

In both cases, you increase the livable space. However, it is not done the same way.

A floor addition project is often more complex than an expansion project but provides a bigger space, in most cases. 

Below you will see how these two projects differ.

Home Expansion

A home expansion is done by adding a structure at ground level. We add a room that is annexed to the existing building, either on piles or on a concrete slab or foundation. The size of the expansion depends on the zoning and other regulations of your municipality.

Floor Addition

A floor addition is made by constructing a floor above the existing building. This involves architectural changes to the existing building, circulation in the house, and more. You can make a full floor addition, or just part of the property.

What are the reasons for extending your house?

An expansion project can seem impressive at first sight, and we don’t always understand its relevance.

However, there are many reasons to expand your home in Quebec.

Here are some good reasons why homeowners choose a home expansion:

6 Ways to expand your home

Regardless of the home’s square footage, homeowners usually long for additional space for a special purpose such as a home office, a home gym, or a patio. 

Before embarking on this type of project, you have to consider municipal ordinances, the neighborhood, and building codes. 

Here are some ideas to consider for your home expansion.

Main floor expansion

Room addition for bigger square footage.

Expanding the ground floor is the most common home expansion project.  This will allow you to expand the home’s footprint in a way that blends with the existing design. You can expand the bathroom, kitchen, bedroom, patio, etc. Typically, an exterior wall is removed and new frame is installed for the additional space and a roof is added.

Other updates that will be needed are electrical and plumbing.

Contractors may also refer to a bump out which involves a minimal expansion of the interior floor space such as adding a breakfast nook or a home office.

Second floor addition

Construction of a second floor in Quebec.

If you need a substantial increase in livable space, the best option is a vertical expansion. You can almost double the interior space by adding a second floor.  Of course, it is also possible to add a second floor directly onto a specific part of the ground floor. The bigger the expansion, the higher the cost.

A second-floor addition is generally more expensive than a ground floor expansion. It is, however, the most ideal option if your property does not have land available for a horizontal expansion.

Covered Patio addition

Covered patios for year-round use.

With more homeowners interested in increased outdoor livable space, enclosing a patio has become a popular way for increasing space that can be used throughout the year.

Covered patios are cost-effective and can be built with minor disruptions to your daily routine. You will be surprised to know that covered patios can be used for many activities such as outdoor dining, entertaining, relaxation, and even as a work area.

Finishing the Attic

Minimalist elegance in the attic.

Add livable space by finishing the attic. You can turn it into a home office, a bedroom suite, a playroom, or a family room.

There could be some challenges such as safety codes, access, insulation, or soundproofing but qualified contractors can offer solutions.

A contractor can also help with the design plan to suit your needs and your budget.

With an attic renovation, you can increase not only your livable space but the value of your home, too!

Finishing the basement

Finished basement turned to master suite.

Finishing the basement increases livable space and resale value. It is a definite advantage if you should ever decide to sell in the future.

The basement can be turned into a family room, a home office, an entertainment room, or even a master suite.

It is a cheaper alternative to buying a new house to gain more livable space.

Adding a floor above a Garage

Bedroom above a garage.

Building a floor above the garage is a cost-effective way of increasing livable space. If you need more space, you can add a bedroom, office, or whatever you need above your garage.

An experienced contractor can help you with the design and construction to ensure your addition fits the architecture of the home.

You will gain more space and increase property value at the same time with this project.
