The national average cost of building a three-season sunroom ranges from $35,000 to $45,000. The lowest amount of money people tend to build sunrooms is about $8,000 while the highest cost for building one is around $90,000.

 Regardless if you’re planning on building a sunroom around the minimum national cost or want to build one that’s closer to the maximum cost, one thing is for sure; sunrooms can be expensive. Here’s how to budget for one, no matter your price point. 


The size of your sunroom will be the biggest determinant of how much it will cost to build. The bigger the sunroom, the higher the cost will be. An 8’ x 10’ sunroom will cost you $6,000 and up while a 12’ x 20’ sunroom will cost upwards of $30,000. 


Where will you be building your new sunroom? Does the site of where you want to build your sunroom have and old construction that needs to be torn down first? Does the construction site have any other issues that will impact preparation? Believe it or not, where you’re located and where you want the location of your sunroom to be in relation to your house will be a determinant for your budget. 

You can budget by asking various sunroom builders about your location and an estimate of how much it would cost to build a sunroom in your area. 

Prefab or Traditional Construct

The main difference between a prefab sunroom and a traditional construct one is where it’s built. Prefab sunrooms are built at a factory, deconstructed into easy to move pieces, and assembled at your home. Traditional construct sunrooms are built from scratch at your house. Prefab sunrooms are generally cheaper so they can be a good option if you want to save some money. 


Are looking to build a three-season sunroom, a four-season sunroom, or something else? There are about seven different types of sunrooms you can create. All of them have different price ranges. 

  • Screen room ($5,000 – $25,000)
  • Integrated sunroom ($12,000 – $25,000)
  • Three season sunroom ($12,500 – $50,000)
  • Four season sunroom ($25,000 – $90,000)
  • Conservatory ($18,000 – $95,000)
  • Solarium ($40,000 – $90,000)
  • Curved eave sunroom ($40,000 – $80,000)

Determining what type of sunroom you want will help you better budget for it.
