Home extension
You need more space. Perhaps you’re dreaming of a larger common area to gather family and friends, or a more spacious basement to maximize storage, create a games room, or even a multifunctional area. For others, the desire is to expand private spaces, such as adding a spacious master suite offering a haven of peace and privacy. Whether for a single level or all three floors, an addition is the solution for adapting your home to your changing needs and lifestyle, without having to move. It’s an investment in your daily comfort and well-being.

Do you have questions? That’s normal. We answer them here.
How do I know what type and size of extension is allowed on my property?
To determine the expansion options available on your property, you should consult your municipality’s planning regulations. These regulations set out rules regarding zoning, maximum height, distances to be respected from the property boundaries (setbacks), as well as the percentage of the property area that the building can occupy (land use coefficient). ESPÉ can help you interpret these regulations and design a project that complies with all applicable standards.
How do I make sure the new space matches the style of my current home?
You can choose to harmonize the extension with the existing architectural style by using similar cladding materials, windows, and roof elements. Alternatively, a bold, modern design can be chosen to create an intentional aesthetic contrast, but it must always blend harmoniously with the surroundings.
When expanding, how can you ensure a proper connection between the old and new structures?
Special attention must be paid to the junction to avoid thermal bridges. A thermal bridge is an area of the envelope where the insulation is discontinuous, which can cause cold spots, increased energy bills, or even condensation and, therefore, the risk of mold. To prevent this problem, it is often necessary to remove part of the existing exterior cladding. This allows the new structure to be properly anchored and ensures continuity of insulation and airtightness. At ESPÉ, we place the utmost importance on these details to guarantee the quality and energy efficiency of each project.
