The Ultimate Guide to Sunroom Additions

Posted July 16, 2021

If you’re thinking of adding a sunroom to your house, you may have a lot of questions on your mind. How much will a sunroom addition cost? What are the benefits? What type of addition should I choose?

We’ll cover all of the above in this quick guide!

First, What is a Sunroom?

A sunroom is an addition to a home that has abundant natural light and often has easy access to the outdoors. You may have also heard sunrooms referred to as solariums or patio rooms. 

Regardless of what you call them, sunrooms are a great space to relax, entertain, or enjoy a family meal on a starry summer night.

Benefits of a Sunroom Addition 

If you’re considering a sunroom addition, you’ve probably already envisioned yourself basking in the warm glow of its bountiful sunlight while sipping your morning tea.

 A sunroom allows you to enjoy the beauty of nature, while avoiding its inconveniences, like mosquitos, rain, and wind.

One of the greatest benefits of a sunroom addition is that it’s more affordable than a full-room addition. Even though it’s less costly, a sunroom still adds square footage and value to your home.

If you choose a four-season sunroom, it will allow you to soak up the sun, while avoiding the cold. Many Ottawa-natives struggle with the winter blues. A sunroom is a great way to boost your morale during the colder months.

A sunroom is also a versatile space where you can set up an office, art studio, or home gym. You’ll feel inspired and motivated by the sunshine and garden view.

Types of Sunrooms 

There are a few different types of sunrooms to consider.  How you want to use your sunroom will influence what type you choose.

Do you want a sunroom you can use year-round? Or are you just looking for a summer oasis that keeps the bugs at bay?

Here’s what you’ll need to know about the different types of sunrooms available.

Three-Season Sunroom

A three-season sunroom can be used spring through fall. Since it’s not insulated, you won’t be able to use it during a harsh Canadian winter. That said, a three-season sunroom is more affordable than some of the other options available.

Four-Season Sunroom

A four-season sunroom can be used year-round, regardless of the weather. It can be heated and cooled like the rest of your house. The insulation will add to the cost, but also provides versatility. 


A solarium is a four-season sunroom made entirely out of glass, including the walls and roof.  It’s the ideal option if you want maximum sunlight to grow plants or get your daily dose of vitamin D. Solariums are often more expensive than regular four-season rooms, because they require more thermally engineered materials.

Screened Porch Enclosure

A screened porch is just what it sounds like: a roofed porch with mesh screens as windows. It’s a great choice if you want to take in all of nature’s sounds and scents, while avoiding pesky bugs and unexpected rain. It’s the least expensive of all the sunroom options.

How Much Does a Sunroom Addition Cost? 

The cost of a sunroom addition depends on many factors, including what type of sunroom you choose. 

If you’re going with a three or four-season sunroom, you’ll have to consider whether you want to go with a prefabricated kit or design-build. Prefabricated kits are known for being less expensive, but the costs can add up, especially if you want customizations.

No matter what type of sunroom addition you choose, the quality of materials and the level of craftsmanship will impact the cost. Quality construction will ensure that you and your family can enjoy your sunroom for years to come.

Other sunroom cost variables include:

  • Building permits
  • HVAC connection
  • Insulation
  • Energy efficiency
  • Location in the home
