Steps for a new project

Where to start ?

A few tips and tricks to help you plan your 4-season sunroom or veranda project.

One of the first things to do before adding a solarium or an extension to your home is to check the feasibility of your project with your municipality. Each municipality has its own regulations and setback requirements.

Unlike many companies in the industry, we offer this service. It can often be difficult for homeowners to fully understand municipal regulations, which is why we contact your city directly to learn about the specific requirements for your property and then design your project accordingly.

At your measuring tapes!

For most people, size is hard to figure out.

Here’s a tip: instead of measuring the space available outside your home, measure a few rooms and try to imagine the dimensions that would suit your project.

To give you a ballpark, most solariums we build range from 12 ft × 12 ft to 20 ft × 10 ft.

Take some time to browse our projects and note their sizes. It’ll help you gauge what might fit your space.

Set a budget

Whether it’s for a home extension or a 3-season veranda, it’s a major project — and setting a clear budget is essential. Browse the projects below to get an idea of the average cost of similar builds.

3 or 4 seasons?

Here’s a simple way to understand the difference between a 3-season veranda, a 3-season+ solarium, and a 4-season extension.

3 seasons
  • Extends your summer season (April–October) while keeping you sheltered from the elements.
  • Lets you enjoy your cooler summer evenings even longer.
3 seasons +
  • Built with Energy Star insulated glass windows, this solarium can be heated, allowing you to enjoy it almost all year round.
  • The 3-season+ solarium is built adjoining the exterior wall of your home.
4 seasons
  • The insulated 4-season solarium becomes a true additional room in your home.
  • The 4-season design allows for a full or partial opening to this new space.
  • You can enjoy it all year round.

Take photos

Take photos of the area where you’d like your solarium to be built. Capture it from every angle, including interior views, then come meet us with your photos and quote — or send them to us at: [info@solariumespacedevie.com](mailto:info@solariumespacedevie.com). This will allow us to refine the costs based on the type of windows or roof.

Compare contractors

The quote is an important step — it helps define your project in terms of space, time, and budget.

Don’t rely solely on price. A 3- or 4-season solarium is a significant investment, which is why it’s essential to work with a licensed RBQ (Régie du bâtiment) general contractor.

On average, it takes about three months between the quote and project completion, covering the design phase, permit application, custom construction, and finishing. It’s a medium-term project.
